Scout Association Pipe Line Pro- The seventh county, Christian, had impor- tant development in 1954, resulting in the 1955 production increase. The number of well completions in Illi- nois in 1955 was about 80 percent higher than in 1953 and was the second highest in Illi- nois history, being exceeded only in 1907 when 4,988 wells were completed. Many of the wells had exceptionally high initial pro- ductions. Several areas of Aux Vases sand- stone production were opened up where many wells had initial productions of more than 500 barrels per day. In the Eldorado Con- solidated pool, where a prolific Waltersburg sandstone lens was discovered near the end of 1954, wells drilled in 1955 had initial pro- ductions up to 4,500 barrels per day. Hydraulic fracture treatment was still commonly used in well completion and in 1955 was important in maintaining the rate of production. In 1954 production from new wells was believed to have nearly balanced the decline in production of older wells still on primary production, and waterflooding and hydraulic fracturing were credited with the increased production. In 1955, in counties with sec- ondary recovery and a normal rate of drill- ing, the production rate remained about the same as in 1954, except in Fayette and Ma- 10 ILLINOIS STATE GEOLOGICAL SURVEY ^HOOtooo^^tvOO^O'tl^OcCrHixooo^O^O^- i^OOM^O^i^'Or- i co CO O co^ooo^ot^cNTrr^ONONcoTfcNCNr^^oo^r^oor^oo^or^^r^^^r^cNoo nh-r)ooh- i o^^ooa\oO'Hoo^^ , t N too(^^DnoN i ^a\r) | ^i^(N^T*<(^t^ c sir ) n» rt -— i O rH^rocNoatN^Mr-vo^o^^ o^rH^rnxMh-n^rih- '-Tr-^r^v^ T3 r o co h- vo r- t^ r- co ^ rH ^- i vo t^ co vo co cn OO cn co cn 4-1 f>l ,_ UT, —1 CO CS^H^HtO^O W->fN TJH "C H T3 hoon^ , ono"io^oo\Hviciona\ooooh^ooo , ooo«ioo O o ioon r-i rn (^ (ni •* io ^cNooONt^n r-- r-~- co on ^o r~- o 'o J2 ■^ o\ (Niflr-i^rxN con-^r^^M o^o cn u-> r- os co 3 "T* Jh T3 £ r- o © *— i r-* \D oo >Hr^o\or) rHi^ r- cn r^ cn o £ cn r^n ^o^ ^o co ^ co o w-> in o as Ih r-H co »— i i— i ro co co i— i cn Oh .• — v O locnooooooooooo^oooooooooooooooooooooo S s 1^ CN OOOOO t-i oo os oaO O <— i CN ^D CN O 5 a v — ' CO !t .2 ei 'c u 3 T3 o "rt O O O" Otj-'OO'-*'— i>-nO l ^cNOooO'* | oocN'*iOO l ^OOOOLocoOOO'* l OOr^OsO Cl- r^- ^TfOrTvOO ^O-— iCNcOCN invi OS CO O 3 ■^ CO CN CO CN GO - ,— i © 'sOco Os , , I— 1 '"'CO rH O o Ih rt >-lVDrHrHO\tNN^r)>OCI'*C>0>^'* , 0'Hr^VlCNrHCN|tN'*^OTtl(SrO'HFHrH^Mr^ 4-1 1— I T— 1 1—1 rt o 2 og 1 .fl o cS oooocoor~-r^coo«^ i ^vocNr--* i r-ooooooo^H'+ | ONOOO , ooO'-HTiHu-> u-» COCN ^0 OO c o -HCNOOOOOCNr^^OO^OOOOOOOOOOOOOOOOOOOOOO CO 3 bD rt C O £ 3 O 0, 4-1 OOOOcococO'— ICNCOO-— KSnrf'taOooOOOOOhtOOOO^OON'- 1© OS -^ cO ^h CO CN CO rf CN CN i-h --h ^h -rf r- o H O 00 C .2 Nn-HpHirir^(>nc>norin^c»oofO'HO'HcO'-itN>oio>^'tcNrov)'H-HcNh.c> \D O-OChO'trO'H^CNcew^rti^ 0\ O CO ^O r- 1 r- 1 .— i u r-H ^H CN » G 3 ■ • • -o -a * " O U C e r- bD s si § !j J . lis! a -§!ls-§ s-t,!!!

Counties and pools with big increases in drilling had increases in produc- tion amounting to about three-fourths of the total increase for the state. Illinois continued to rank eighth in oil production in the United States in 1955, al- though it moved into seventh place several times for short intervals. Daily average pro- duction increased throughout the first six months, and then leveled off as shown in the following summary by months: Month Barrels January 202,000 February 211,000 March 218,000 April 221,000 May 225,000 June 233,000 July 223,000 August 225,000 September 231,000 October 225,000 November 225,000 December 228,000 At the beginning of 1955, most crude oil in Illinois was selling at $2.95 a barrel. In March there was a price reduction of 5 cents per barrel. In October the price was in- creased to $3.00, remaining at that figure throughout the remainder of the year. Value (at the wells) of crude oil produced in 1955 was about $238,000,000. To this should be added the value of natural gasoline and lique- fied petroleum gas extracted from Illinois natural gas, estimated at $4,500,000, making a total of $242,500,000. DRILLING AND DEVELOPMENT A total of 3,885* wells were drilled for oil and gas in Illinois in 1955 (tables 1 and 2), an increase of about 20 percent over the 3,254 wells drilled during 1954. Of the 3,885 wells completed, 2,084 were oil wells and 18 were shut-in gas wells. This is about the same percentage (55 percent) of success- ful completions as in 1954. In 1952 only 38 percent were successful. There were 1,047 dry holes in pools, and 736 unsuccessful wildcats in 1955. The per- * Well-completion figures are based on reports received through the Illinois Basin Scout Association. An undeter- mined number of additional wells were completed in the old fields of Clark, Crawford, Lawrence, and adjoining counties, for the most part in waterflood areas. centage of wildcat wells drilled showed a slight increase to 22 compared with 21 in 1954, but still was considerably below the 1952 figure of 32 percent. Pool Development Wells were drilled for oil or gas in 60 counties in 1955; 59 counties reported wild- cat wells, but only 42 had pool wells. Over a third of all drilling was concentrated in four counties. White County, with 478 wells drilled, remained in first place. Saline County, ranking second with 355 comple- tions, showed the biggest increase in drilling of any county. It had never previously placed among the half dozen most active counties. Lawrence County also recorded a big in- crease in drilling to place third. One of the biggest decreases in drilling was in Wayne County, which dropped to fourth place after several years of being either first or second. Clay and Wabash counties also recorded major decreases in drilling in contrast to the increase for the entire state. The first successful wells ever drilled in Douglas and Adams counties were completed during the year. A small oil well completed in Douglas County was the discovery well of the Murdock pool, and a shut-in gas well was drilled in Adams County in the Fishhook gas pool ; the rest of the pool is in Pike County. During 1953 and 1954, drilling in the state moved northward. One of the outstand- ing developments of this period was in the Decatur-Mt. Auburn-Springfield area. Ex- ploration in the Macon-Christian-Sangamon County area continued into 1955, and five new pools were discovered, four in Christian County and one in Sangamon County. Only one of these, Kincaid South, appeared prom- ising. Results of drilling were disappointing, and the rate of drilling decreased within a few months so that Macon and Christian counties had only about half as many com- pletions in 1955 as in 1954. Sangamon, Moultrie, and Douglas counties showed big increases in drilling but with unsatisfactory results. At the end of 1955, development had be- gun in three northern areas that showed promise. In Christian County the Kincaid South pool, discovered in November 1955, DRILLING AND DEVELOPMENT 13 had 10 producing wells completed and others drilling. The producing wells were scattered over an area of almost a square mile, and there were no dry holes. In Coles County the Cooks Mills pool was discovered in 1941 and Cooks Mills North in 1946, but both were abandoned. In 1954, however, Cooks Mills East was dis- covered, and in 1955 Cooks Mills Gas. By the end of 1955 oil and gas wells were scattered throughout an area about 3% miles long by 1 mile wide, and development was progress- ing rapidly. Most of the gas was in the Cy- press sandstone and the oil in the Rosiclare. The third northern area was around Oak Point in Clark County. The Oak Point pool was discovered in 1952 and almost im- mediately abandoned as a one-well Pennsyl- vanian sandstone pool. In 1955 Aux Vases sandstone production was discovered in the Oak Point pool, followed by discovery of the Oak Point West pool, and by the end of the year a big development program was in prog- ress. On the western side of the Illinois basin, attempts to extend Devonian-Silurian pro- duction southward from Christian County resulted in four new Devonian or Silurian pools in Bond and Washington counties and opened up good Devonian sandstone exten- sions to the Sorento and Woburn Consoli- dated pools. Both pools previously had had smaller Devonian wells. Results of the search for deep production in Bond, Clinton, and Washington counties were promising enough to warrant continuing exploratory drilling in 1956. Most important event of the year was the development in the Eldorado area on the southern edge of the basin. This is discussed in detail below. Within the deeper part of the basin the most important development was the discov- ery and drilling of a Salem limestone pay in thejasper County portion of the Clay City Consolidated pool. About 50 good Salem wells were completed, most of them on leases al- ready producing from the Rosiclare or Mc- Closky. Pools having the greatest number of pro- ducing wells completed during the year were Clay City Consolidated with 336, Lawrence with 157, Eldorado with 151, and Main Consolidated with 119. Depth of producing wells drilled during 1955 varied from about 400 feet to about 4,000 feet, with an average depth of 2,320 feet. Average depth of all wells drilled in 1955 was 2,385 feet. In fields discovered since January 1, 1937, 21,290 wells were producing oil or gas at the end of 1955; in older fields the number was approximately 9,175. Illinois thus had about 30,460 wells producing at the end of 1955. Eldorado Area The Eldorado pool was discovered in 1941 north of the town of Eldorado in northern- most Saline County. Two producing wells were completed in 1941, one in the Aux Vases sandstone and one in the McClosky limestone. The McClosky well was later opened up in the Tar Springs sandstone. A third well was drilled in 1950, adding a fourth pay, the Palestine, to the pool. An- nual production from 1941 through 1952 was between 1,000 and 3,000 barrels. In 1953 a period of exploration and drill- ing began that culminated late in 1955. Fifteen wells were drilled in 1953, all of them north of the town of Eldorado. Pro- duction, all of which was from the Hardins- burg and Aux Vases sandstones, increased to 92,000 barrels for the year. East of the town, the Eldorado East pool was discovered, and at the end of 1953 it had three Aux Vases wells and had produced 14,000 barrels of oil. In 1954 the Eldorado Central pool was discovered in the Beulah Heights area on the west side of the town of Eldorado. The El- dorado and Eldorado Central pools grew together rapidly and were consolidated before the end of the year. The Eldorado North pool also was dis- covered in 1954 about three miles northeast of town, and four small wells were com- pleted in the Waltersburg sandstone. Sev- eral small Waltersburg wells also were drilled on the southeast edge of the north- ward-trending Eldorado Consolidated pool. 14 ILLINOIS STATE GEOLOGICAL SURVEY In December 1954 two 1,100-barrel Wal- tersburg wells were completed, one in the eastern part of town and the other about halfway between town and the Eldorado North pool. The combined 1954 production of Eldo- rado Consolidated and Eldorado North was 463,000 barrels. By the end of the year 55 producing wells had been completed in the two pools. During the early part of 1955, drilling was concentrated in the area between the town of Eldorado and the Eldorado North pool, which was soon joined to Eldorado Consolidated. Most of the wells produced from a Waltersburg sandstone lens that trends west-southwest and is about four miles long, three-fourths of a mile in maximum width, and in places more than 50 feet thick. Oil or gas wells drilled in the Waltersburg totaled 122. Twenty-seven wells were completed in other pays, most of them in the northward- trending older part of Eldorado Consoli- dated, and a few along the edges of the Wal- tersburg lens. Eight other pays produce in the pool. Next to the Waltersburg, the Aux Vases pay produces in the most wells of the Eldorado Consolidated pool. The other pro- ducing pays in the pool include the Palestine, Tar Springs, Cypress, Paint Creek, Ohara, Rosiclare, and McClosky. The Waltersburg lens in the Eldorado Consolidated pool is a gas-cap pool. The first wells drilled had very high gas-oil ratios. Early in March 1955 about 55,000,000 cubic feet of gas was being produced daily, almost all of which was flared. Gas produc- tion declined rapidly, and by the end of 1955 it was down to about 10,000,000 cubic feet per day. Variations in initial production of oil wells in the Eldorado Consolidated pool were great ; although some of the wells were small, many produced more than 500 barrels daily, and the best one was reported as having made 4,500 barrels initially. The Eldorado Con- solidated pool reached its peak production of about 20,000 barrels per day in May. Production for 1955 was 3,523,000 barrels, compared with a total of 551,000 barrels for the previous 14 years. In the Eldorado area the first half of 1955 was primarily a period of pool development drilling, the second half one of exploratory drilling. The Waltersburg lens is a south- west extension of the previously discovered Waltersburg production area in the Roland Consolidated pool, about a mile west of Omaha in the Gallatin County part of the pool. Much of the exploratory drilling in 1955 was "trend" drilling, attempting to discover a possible westward continuation of the Waltersburg sandstone from Roland Con- solidated through Eldorado Consolidated into untested areas. In July two new pools were discovered, in August one pool, in September three, and in December two. In addition to these eight new pools, oil was discovered in the one-well Harrisburg gas pool, and eight Waltersburg and one Tar Springs oil wells were drilled before the end of 1955. All pro- duction, old and new, in the Eldorado area is from Mississippian formations. By the end of 1955, the Waltersburg sand- stone lens of the Eldorado Consolidated pool was drilled up. Only two of the new pools, Harco East and Raleigh South, promised to be better than two- or three-well pools. Drill- ing in the area dropped off and production declined as the high initial production of wells drilled in the spring leveled off into settled production. Production and drilling rates in 1956, although continuing higher than normal in the Eldorado area, should be much lower than in 1955. Exploratory Drilling and Discoveries Wildcat wells were drilled in 59 counties in 1955; new pools were discovered in 19. Eight of the new pools are in Saline County, four in Christian, and four in Washington. Of the 3,885 wells drilled in 1955, 846, or about 21.8 percent, were wildcats. The 324 wildcat wells drilled more than 2 miles from production (table 3) discovered 17 new pools, or 1 in 19 successful (5.2 percent). All of these 17 new pools, however, appear to DRILLING AND DEVELOPMENT 15 be very small. The 522 wildcats drilled less than 2 miles from production discovered 15 new pools and 78 extensions to pools, or were about one in 5^ (17.8 percent) successful. Three new pools and seven extensions were discovered by reworking wildcat wells that previously had been completed as dry holes. None of the 10 workover wells was deepened.

Thirty-two new oil and three new gas pools (table 4 and fig. 2), 85 extensions to pools (table 5), and 36 new pays in pools in 34 wells (table 6) were discovered during 1955. One new pool, Cooks Mills Gas, was lost during the year by consolidation with Cooks Mills Consolidated. In the remaining 34 new pools, seven nonoperated gas wells and 65 oil wells had been completed by the end of the year. Twelve of the oil wells were in Exchange East, largest of the new pools. Kincaid South, which was not dis- covered until November, had 10 wells by the end of December and seemed to be best of the 1955 pools. The Fishhook Gas pool had six shut-in gas wells and Raleigh South had six oil wells. The other new pools had from one to three wells each. It was noted in 1954 that most of the new pools were around the margins of the pro- ducing area. Most of the 1955 new pool dis- coveries also are marginal, showing the in- fluence of 1954 discoveries and development. Nine, or one-fourth, of the new pools are in Saline and Gallatin counties around the Eldorado Consolidated pool. To the north- west, five new pools in Christian and Sanga- mon counties are the result of exploration around the Mt. Auburn-Edinburg West area, development of w T hich was the out- standing feature of 1954 drilling. Four of the new pools lie along the north- east margin, including Murdock, the first Douglas County pool. On the east edge of the producing area, Lawrence County had two new pools, and on the west, Washing- ton, Bond, Madison, and St. Clair counties had seven. Pike County, even more remote, had one gas discovery. Only a half dozen new pools were within the highly productive area of the state. Two new pools, Murdock in Douglas County and Redmon North Gas in Edgar County, produce from the Pennsylvanian. Each is a one-well pool. Ten new oil pools and one gas pool, all lying in a western belt extending from Chris- tian through Washington County, produce from the Silurian or Devonian. Twelve pools produce from upper Mississippian sandstone, and 10 from the lower Mississippian. One well in the Louden pool was deep- ened to the Trenton limestone and is pro- ducing a little oil. No other new Trenton production was discovered during the year. One 1955 well in the Gays pool (Moultrie County) was completed in the Aux Vases and Devonian, the Devonian being a new pay in the pool. The remaining 34 new pays are Mississippian in age. Unsuccessful Trenton tests were made in the Sorento, Carlinville, and Okawville pools. A selected list of important unsuccessful deep tests and wildcats is given in table 7. One shallow wildcat in Union County is listed because it was reported as having the first good oil show in the county. No gravity meter or magnetometer work was done in Illinois in 1955.

The 84 wells completed in 1955 include 35 oil wells and 29 dry holes in pools, and eight successful and 12 unsuccessful wild- cats. Two new pools were discovered, Albion Central and Samsville Northwest. Both are in areas which have been extensively devel- oped, so neither can become very large with- out being consolidated with an older pool. The other six successful wildcats were ex- tensions to pools. Changes in rate of production for most of the pools were small. The one big change was in the Albion Consolidated pool, which produced 881,000 barrels in 1955 in Ed- wards County (pool extends into White County), an increase of 182,000 barrels for the year. Albion Consolidated is now re- sponsible for more than half the oil produced in Edwards County. During the past 10 years production has fluctuated between 6,000,000 and 9,000,000 barrels annually, secondary recovery and new well drilling hav- ing prevented normal decline. Four other Edwards County pools made between 90,000 and 120,000 barrels each during 1955: Parkersburg Consolidated, Maple Grove Consolidated, Ellery Consoli- dated, and Ellery East. Most of the 17 other producing oil fields are small in size with little production. Albion East, Bone Gap Consolidated, Browns, Phillipstown Consolidated, and New Harmony Consoli- dated have all produced large quantities of oil, but are old, and production has dropped off considerably. Many of the pools in Ed- wards County extend into other counties. All data as given apply only to those por- tions of such pools as lie within Edwards County. All production in Edwards County has been from Mississippian or Pennsylvanian pays, the latter being important only in Albion Consolidated. There has been very little testing of the pre-Mississippian forma- tions. The Pennsylvanian and Mississip- pian probably have been more intensively tested in Edwards than in any other county except Wabash, so the future of Edwards County depends to a great extent upon ex- pansion of secondary recovery operations and possible development of deeper pays. Effingham County (FIG. 16, AREA 11) Drilling and production both increased in Effingham County in 1955. One pool, Hill East, a 1954 discovery, must be given credit for both increases. The number of wells drilled increased from 39 in 1954 to 58 in 1955; 24 of the latter were producers. Twenty-three of these were in Hill East. The 34 dry holes included 22 in pools and 12 wildcats. No new pool was discovered, but three of the new producing wells in Hill East were drilled as wildcats and completed as pool extensions. Prior to 1955, production in Hill East was from the Ste. Genevieve; 21 of the 1955 wells were completed in the Cy- press sandstone. Effingham County production for 1955 was 553,000 barrels, 80 percent of which came from its three largest pools. One of these was Hill East. The other two, Sailor Springs Consolidated and Iola Consolidated, have their major area and production in Clay County. The Louden pool, which has a small extension from Fayette into Effingham County, produced about 54,000 barrels of oil in 1955, or another 10 percent of the county's production. The remaining 10 percent came from eight small pools (Mason North, Evers, Lillyville, Eberle, Bible Grove North, Ma- son, Elliottstown East and Elliottstown North). Effingham County has produced a total of about 7,218,000 barrels of oil. Oil production in Effingham County is limited to a small part of the stratigraphic section. There are no wells in strata younger than the Cypress sandstone or older than the Ste. Genevieve limestones. Fayette County (FIG. 16, AREA 11) Although only 18 wells, 14 of which were dry, were drilled in Fayette County in 1955, production for the year increased and the county remained among the leading oil pro- ducers in Illinois. COUNTY REPORTS 53 Fayette County is unique in that although only five pools have been discovered and most of its production comes from one pool, yet it is habitually one of the four leading produc- ing counties. Most of the drilling in the county was done between 1937 and 1942. Dis- covery of an extension to the Louden pool brought a period of increased activity during 1949 and 1950. Except for these two periods, the normal rate of drilling has averaged about 20 to 30 wells per year. In 1955, with only four new producing wells for the year, Fayette County's production was the highest for any year since 1946. Fayette County in 1955 produced 8,075,- 000 barrels of oil, making a total production of 202,140,000 barrels. The Louden pool produced 7,654,000 barrels in 1955 for an all-time total of 188,041,000 barrels. St. James, the second largest pool, made 380,000 barrels in 1955 for a total of 13,336,000 bar- rels. St. Paul, Patoka West, and Laclede had a combined production of less than 40,- 000 barrels. In 1955 a well in the Louden pool was suc- cessfully deepened to the Trenton, becoming the first Trenton well in the county. "I he initial production was 21 barrels of oil and 400 of water, so the Trenton cannot yet be considered a commercial pay zone. Most of the oil in the county is being produced from the Cypress, Paint Creek, and Bethel sand- stones and from the Devonian limestone (in Louden only), but there is minor production from the Pennsylvanian and from other Mis- sissippian pays. Franklin County (FIG. 15, AREA 10) The amount of drilling in Franklin County has fluctuated more than that in most coun- ties. The 1955 total of 53 wells drilled is an increase of 17 wells over 1954 and is about the median rate since 1937. The 1955 wells included 27 oil wells, 12 dry holes in pools, and one successful and 13 unsuccessful wild- cats. The one successful wildcat discovered a pool extension rather than a new pool. Benton is the only big pool in the county. It is now producing about two-thirds of the Franklin County oil, and has produced about three-quarters of the total production. The Benton pool was the first big waterflood project in the state; it is now producing a little less than half as much oil as at the peak of secondary recovery production. This, how- ever, is almost three times higher than 1949 production, before the waterflood program was in effect. Production for 1955 was 1,- 441,000 barrels bringing total production for the pool up to 31,659,000 barrels. Four other pools, Benton North, Christo- pher Consolidated, West Frankfort, and Whittington, each produced between 100,- 000 and 200,000 barrels for the year. Dale Consolidated and Sesser each made between 85,000 and 90,000 barrels. The nine other active pools had a combined 1955 produc- tion of 160,000 barrels. One of these, Thompsonville North, has produced more than lVo million barrels of oil in the past 10 years, but production has now dropped to a low rate. Total production in the county for the year was 2,285,000 barrels of oil, bringing the cumulative total up to 41,887,- 000 barrels. The Tar Springs sandstone is the best oil pay in the county and the only pay in the Benton pool. Most of the wells drilled in 1955 produce from the Aux Vases sand- stone, which currently is the second most productive sandstone in Franklin County. Hancock and McDonough Counties Hancock and McDonough counties share a single oil pool and are treated as a unit because production cannot be separated. In 1955 there was a little more drilling than usual in the two counties. McDonough had 12 wells completed — two oil wells, three dry holes in pools, and seven wildcats. Han- cock had only three wells — one dry pool test and two wildcats. Oil production from the Colmar-Ply- mouth pool was 71,000 barrels in 1955, a slight increase over 1954. Total production fcr the two counties is 4,013,000 barrels. There is no reason for anticipating any considerable variation in amount of drilling or production in the next few years. 54 ILLINOIS STATE GEOLOGICAL SURVEY Gallatin County (FIG. 7, AREA 2) In 1955 drilling more than doubled and production almost doubled the 1954 figures in Gallatin County. More wells were drilled than in any other year except 1948, and production was higher than in any other year except 1949. The county ranked sixth in the state in drilling for 1955. Two hundred wells were completed, in- cluding 118 oil wells, 55 dry holes in pools, and 27 unsuccessful wildcats. The 118 new oil wells include 14 successful wildcats that discovered one new pool (Elba) and 13 ex- tensions to pools. The ratio of one out of every three wildcats successful is extremely high, but most of the wildcats were drilled within a mile of production. There was no concentration of drilling in any one pool as in some other counties. Pro- ducing wells were drilled in 14 pools. Herald Consolidated had 35 new wells, Inman West Consolidated 30, and Inman East Consoli- dated 21. Most of the other pools had only two or three new wells. The biggest production gain was in the In- man East Consolidated pool, which produced 1,034,000 barrels of oil for the year. Herald Consolidated and Roland Consolidated, both of which have most of their productive acre- age in White County, produced about half a million barrels each. The three pools more than doubled their 1954 production. Inman West Consolidated, the only other big pool in the county, produced 379,000 barrels, very slightly increasing its 1954 mark. The above four pools produced 2,418,000 barrels of the county's 1955 oil production of 2,675,000 barrels. About half of the re- mainder came from the Omaha pool and the rest from 10 small pools. Gallatin County has produced about 22,936,000 barrels of oil. Three of the oil wells drilled in Gallatin County in 1955 produce from the Pennsyl- vanian. The others produce from all of the upper Mississippian pays and from the Ste. Genevieve. There is no older production in the county. Hamilton County (FIG. 6, AREA 1) Hamilton County made impressive gains in 1955. It jumped from fifteenth place with only 77 completions in 1954 to eighth place with 191 completions in 1955. In 1954 only 42 percent of Hamilton County wells were completed as producers; in 1955, 58 percent were successful. Production for 1955 was 3,846,000 barrels, an increase of about half a million barrels over 1954. Total produc- tion for the county rose to 75,588,000 bar- rels. Of the 191 wells drilled in 1955, 110 were producing wells, 58 were dry holes in pools, and 23 were wildcats. Most of the new production for 1955 was at the southwest end of the Dale Consoli- dated pool in the southwestern corner of the county. Almost all the new wells, includ- ing those in other pools, produce from the Aux Vases sandstone. Initial daily produc- tions were high, averaging nearly 300 barrels per well compared with an average of less than 100 barrels for all new wells in the state. Many of the wells had daily initial productions of 500 barrels or more. Most of the wells were fractured during the com- pletion process. The Dale Consolidated pool had 94 new producers within the limits of Hamilton County, all but one of which were com- pleted in the Aux Vases sandstone. Produc- tion of Dale Consolidated in 1955 increased almost half a million barrels, reaching 2,804,- 000 barrels and raising its total to 54,430,000 barrels. During the year Rural Hill West, Cantrell Consolidated, West End, and Flan- nigan were consolidated with Dale Consoli- dated. One other pool, Bungay Consolidated, also showed noteworthy increases in 1955. Four- teen Aux Vases sandstone wells were com- pleted. Production increased 300,000 bar- rels, the total for 1955 being 802,000 bar- rels, and the cumulative total 8,687,000 barrels. Three other pools, Mill Shoals, Thackeray, and Walpole, produced over 100,000 barrels each in 1955, but in general there was little COUNTY REPORTS 55 drilling and production declined outside of the Dale Consolidated and Bungay Consoli- dated pools. Although the southwestern end of the Dale Consolidated pool was still being developed at the end of the year, it seemed probable that much of this development in 1956 would be in Saline and Franklin Counties. Jackson County (Fig. 23, area 18) No oil production was reported for 1955 for Jackson County. There are two pools, one of which, Ava-Campbell Hill, was aban- doned in 1943. Elkville, a one-well pool, has had no pipe line runs in the past four years. Five wells, two of them dry holes in pools and the other three unsuccessful wildcats, were drilled in 1955. This is about the usual amount of drilling. There is no reason for anticipating any change in 1956. Jasper County (FIG. 13, AREA 8) Jasper County showed outstanding gains in both drilling and production in 1955. In 1954 it had ranked twenty-third in drilling in Illinois, with only 27 wells completed; in 1955 it ranked ninth, with 165 wells com- pleted. Wells drilled in 1955 included 117 oil wells, 30 dry holes in pools, and 18 unsuc- cessful wildcats. Two wildcat wells were successfully completed as extensions to the Clay City Consolidated pool. All the new oil wells were in the Clay City Consolidated pool. Part of the new drilling was development of a deeper pay zone under land already pro- ducing. A new Salem limestone producing area had been discovered at the end of 1954 underlying Rosiclare and McClosky produc- tion. In 1955, 53 Salem wells were drilled in the Clay City Consolidated pool, most of them in areas already producing. Most of the other wells were edge wells completed in the Ste. Genevieve. The Clay City Con- solidated pool lies in four counties and the production noted for the Jasper County por- tion is an estimate. New drilling in 1955 is estimated to have increased production to about 2,000,000 barrels, an increase of about half a million barrels. Total production for the Jasper County portion of Clay City Con- solidated is estimated at 27,000,000 barrels. There are nine other active oil pools in Jasper County. Combined production for the nine for 1955 was 104,000 barrels, a de- crease of about 5,000 barrels from the 1954 total. Eight other pools are abandoned or shut down. Total production for all Jas- per County pools, excluding Clay City Con- solidated, amounts to 3,007,000 barrels. By the end of 1955 the drilling peak ap- peared to have passed, indicating a decrease in drilling for 1956, but drilling should con- tinue at a higher rate than in 1954. Jefferson County (FIG. 15, AREA 10) Drilling dropped off a little in 1955 in Jefferson County after reaching a higher than normal rate in 1954. There were 85 wells drilled, 43 of which were completed as pro- ducers, 27 as dry holes in pools, and 15 as unsuccessful wildcats. No new pool was dis- covered, but two of the 43 successful wells were drilled as wildcats and completed as extensions to pools. Production for Jefferson County in 1955 was 2,506,000 barrels, an increase of 235,000 barrels for the year. Total production to the end of 1955 was 47,515,000 barrels. Most of the 1955 drilling was confined to two pools: King with 17 new oil wells and Irvington East with 16. The new wells in the King pool produce from the Aux Vases sandstone. In the Irvington East pool, four Penn- sylvanian sandstone wells had produced 7,000 barrels of oil in the four years from 1951 to 1954. In 1955 two new pays, the Cypress and Bethel sandstones, were discovered in Irvington East, and the sixteen 1955 wells produce from these two pays. Production for the year was 65,000 barrels. About 2,000,000 barrels of the 1955 pro- duction came from the five largest pools, two of which had substantial increases. Boyd, which has the largest annual production, shows the results of waterflooding in its in- crease in production from 557,000 barrels in 56 ILLINOIS STATE GEOLOGICAL SURVEY 1954 to 689,000 barrels in 1955. The Jeffer- son County portion of Salem Consolidated produced 403,000 barrels in 1955, an in- crease of 87,000 barrels. Except for Irvington East, as noted above, all other pools showed declines or only minor increases in production. As most pools in Jefferson County are from eight to fifteen years old, declines in production are to be expected except where secondary recovery operations are effective. Lawrence County (FIG. 9, AREA 4) Lawrence County pools and production are considered in two groups — pools discov- ered in 1906 (Lawrence and St. Francis- ville), and pools discovered since 1937. Development of the Lawrence pool oc- curred for the most part within 10 or 15 years from the date of its discovery. For the following 30 years, and especially after 1937, there was only a small amount of drilling. Annual completions for Lawrence County averaged about 20 wells and rarely ex- ceeded 50. In the last three or four years, however, interest in testing for new pays in the old Lawrence pool has grown. As a re- sult, 157 new oil wells were added to the Lawrence pool in 1955. Clay City Consoli- dated is the only Illinois pool to exceed this number. Two new oil wells were drilled in the St. Francisville pool also. Production from the two pools in 1955 was 3,479,000 barrels, an increase of about 600,000 barrels over 1954. Total production for the two pools to the end of 1955 was 257,811,000 barrels. Twelve pools have been discovered since 1937, including two discovered in 1955. The 1955 discoveries, Pinkstaff East and Russell- ville West, each consisted of a single well at the end of the year with no more drilling in prospect. Three of the 12 pools have been aban- doned, and most of the others are small. In Russellville Gas, once the biggest gas pool in Illinois, the Pennsylvanian gas has been depleted and one well, deepened to the Mc- Closky, is producing about 1,000 barrels of oil per year. Production from the post-1937 pools was about 355,000 barrels in 1955, making their cumulative production about 3,562,000 bar- rels, little more than the Lawrence pool pro- duced in 1955. Most of the 355,000 barrels came from 4 pools: Ruark (117,000 bar- rels), Ruark West Consolidated (131,000 barrels), Lawrence West (71,000 barrels), and St. Francisville East (22,000 barrels). Lawrence is one of the counties that showed large increases in drilling in 1955. The number of wells completed jumped from 141 in 1954 to 255 in 1955, putting Lawrence in third place in the state behind White and Saline counties. Of the 255 wells reported completed in Lawrence County, 175 were oil wells, 63 were dry holes in pools, and 17 were unsuccessful wildcats. Secondary re- covery operations are extensive in the Law- rence pool, and the Basin Scout Association seldom reports wells drilled on such proj- ects, so the number of wells actually drilled in Lawrence County may be much greater than the above figures indicate. Macon County (FIG. 1-8, AREA 13) Macon County's "oil boom," which began in December 1953 and extended through 1954, almost ended in 1955. Well comple- tions dropped from a high of 49 in 1954 to 17 in 1955. Only one of the 17 wells was successful. There were four unsuccessful pool tests and 12 unsuccessful wildcats. The producing well was in the Oakley pool. Four pools in Macon County had produc- tion in 1955. The 10 wells in the Macon County part of the Blackland pool produced 93,000 barrels of oil for the year. The other three pools, Decatur, Oakley, and Harris- town, produced 11,000 barrels from a com- bined total of 13 wells. Total production for 1955 was 104,000 barrels, which brought the total production for the county to 191,000 barrels, 171,000 of which has come from the Blackland pool. All the Macon County wells produce from the Silurian or Devonian. It seems doubtful that many of the wells producing in 1955 will pay for themselves. Unless a new and better pool is discovered, drilling in Macon COUXTY REPORTS 57 County probably will revert to its pre-1954 rate with only five or six wells drilled per year. Macoupin County (FIG. 20, AREA 15) Although oil was discovered in Macoupin County almost 50 years ago (in 1909), pro- ducing wells have been few in number and production insignificant. Nineteen wells were drilled in 1955, 5 dry holes in pools and 14 wildcats. One of the pool dry holes was a Trenton test in the Car- linville pool. Carlinville, the oldest pool in the county, has some unplugged wells that occasionally are pumped. The other old oil pool, Gillespie-Wyen, also produces a little oil occasionally. Three gas pools, Spanish Needle Creek, Staunton, and Gillespie-Benld, have been abandoned. Four oil pools have been discovered in the past 15 years. Three of these, Plainview, Staunton, and Staunton West, consist of a single well each. Most of the wells in Car- linville North, the fourth pool, have been abandoned. Production from wells that have not been plugged in the four pools is inter- mittent and totals at most a few hundred barrels a year. Total production for the county is unknown, but it probably is only a few thousand barrels. All production in Macoupin County is Pennsylvanian in age. Most of the county is outside the area believed to have the best prospects for future development, so it is doubtful that Macoupin will ever be an im- portant oil-producing county. Madison County (FIG. 22, AREA 17) The year 1955 was one of the least success- ful for the oil industry in Madison County since 1943. Of 34 wells drilled, four were completed as shallow Pennsylvanian sand- stone oil wells in the Livingston South pool, 15 were dry holes in pools, and 15 were un- successful wildcats. One new pool was named in 1955. The discovery well originally was completed as a temporarily abandoned well, then put on the pump in 1954. By the end of 1955 it had produced 1,000 barrels of oil and was named the discovery well of the St. Jacob East pool. Production is from the Sylamore sandstone in the Devonian system. About three-fourths of the Madison County production comes from the Silurian reef and the overlying Devonian limestones of the Marine pool. The pool produced 349,- 000 barrels in 1955, bringing its total pro- duction up to 9,271,000 barrels. The St. Jacob pool is second in impor- tance, with a production record of 70,000 bar- rels for 1955 and a total of 2,741,000 barrels, all from the Trenton limestone. The Livingston and Livingston South pools produce from a shallow Pennsylvanian sandstone. Their combined production was 68,000 barrels for 1955; cumulative produc- tion for the two pools is 454,000 barrels. Livingston East consists of a single gas well that has been shut in since completion. Madison County has produced 12,469,000 barrels of oil, including 1,000 barrels from the old abandoned Collinsville pool. Pro- duction in 1955 was 488,000 barrels. There is no Mississippian oil production in Madison County. Three pools produce from the Pennsylvanian, two from the De- vonian and or Silurian, and one from the Trenton. Marion County (FIG. 17, AREA 12) In 1955 Marion County recorded a de- cided increase in production, but one of the biggest decreases in drilling for any county in the state. The Salem Consolidated pool was almost entirely responsible for both changes. During 1953 and 1954 a Rosiclare sand- stone extension to the Salem Consolidated pool was being developed. By the end of 1954 it was almost drilled up, and only a few holes were completed in 1955. The 1954 drilling may be responsible for some of the increased production. Most of it, however, is due to expanded, highly successful water- flooding in the Salem Unit of the Salem Con- solidated pool. Production, which had been about 5,000,000 barrels annually in the 58 ILLINOIS STATE GEOLOGICAL SURVEY Marion County portion of the Salem Con- solidated pool, increased to 7,210,000 bar- rels in 1955. Production during 1955 was about 8,725,- 000 barrels from pools discovered since 1937 and about 50,000 barrels from old pools. Production in 1954 was about 6,500,000 bar- rels. Total production is about 284,725,000 barrels. Drilling dropped from 182 comple- tions in 1954 to 92 completions in 1955, in- cluding 52 oil wells, 21 dry holes in pools, and 19 unsuccessful wildcats. A total of 24 wildcat wells were drilled, five of which were successful and discovered two new pools (Ex- change East and Iuka West) and three ex- tensions to pools. Most of the new oil wells were in the Iuka, Exchange East, and Salem Consolidated pools, and produce from the Ste. Genevieve or St. Louis formations. The Exchange East pool is one of the best pools discovered in 1955 in Illinois. By the end of the year it had 12 oil wells and had produced 78,000 barrels of oil. The Iuka pool, discovered in 1947, had little drilling or production before 1954. In 1954, 16 oil wells were completed and in 1955, 18 were completed. Production for 1955 was 306,000 barrels out of a total of 462,000 barrels cumulative production. An unsuccessful Devonian test was drilled in the Iuka pool, but no new pre-Mississip- pian production was discovered in Marion County in 1955. Marion County ranks first in the state in total production. Although many counties have more drilling and White County now leads in annual production, the size and suc- cess of the Salem secondary recovery project should keep Marion County in first place for cumulative production for several years more. Monroe County (FIG. 24, AREA 19) Monroe County has been an oil producing county, but can scarcely be considered as such at present. Its only pool, Waterloo, was discovered in 1920 and most of it converted into under- ground gas storage in 1951. Three produc- ing wells were left at the south end of the pool. Total production for the pool is about 37,000 barrels, and the amount produced since 1951 is insignificant. One well, a dry hole, was drilled in the Waterloo pool in 1955. Montgomery County (FIG. 20, AREA 15) Montgomery County is the oldest oil pro- ducing county in Illinois, but its pools are small and the wells low in production. In about 75 years of production, Montgomery probably has produced less than 75,000 bar- rels of oil. The two newest pools, Raymond East and Panama, produced about 5,000 barrels of oil in 1955. The other four pools, Litchfield, Mt. Olive, Raymond, and Waggoner, are abandoned or shut down for the most part, but occasionally produce a little oil. Of the 15 wells drilled in Montgomery County in 1955, four were completed as dry holes in pools, and 11 as unsuccessful wild- cats. Morgan County Seven wells were drilled in Morgan County in 1955 — one gas well in the Pren- tice pool, three pool dry holes, and three dry wildcat wells. The Prentice pool, discovered in 1953, consists of six gas and two oil wells. No oil or gas has been marketed. The pay zone is a shallow Pennsylvanian sandstone. The Waverly pool, discovered in 1946, has had one Devonian oil well and one Pennsyl- vanian and seven Devonian gas wells com- pleted. No oil has been marketed. In 1954 an attempt was begun to use the Waverly pool for underground storage of gas. Earli- est results were unsatisfactory, but experi- mental work continued in 1955. Morgan County has had one other gas pool, Jacksonville, which was discovered in 1910 and abandoned in 1939. Amount of gas produced is not known. There is no good oil or gas production within 20 miles of Morgan County at pres- ent. Although more wells similar to those at Waverly and Prentice may be drilled, it COUNTY REPORTS 59 is doubtful that Morgan County will ever be really productive. Moultrie County (FIG. 19, AREA 14) Oil development in Moultrie County in 1955 was the most promising in its history. Previously the county had one pool, Gays, consisting of a single Aux Vases well. Dis- covered in 1946, Gays was abandoned in 1950 after producing less than 500 barrels of oil. In 1955, nine wells were completed in the county, of which four were producing wells in the revived Gays pool. Three of these wells were reported as producing from the Aux Vases sandstone and one as a dual com- pletion in the Aux Vases and the Devonian. For the first few months of 1955 consid- erable interest was shown in Moultrie Coun- ty. However, the four producing wells were small, their production for the year being only 11,000 barrels. Two dry holes were drilled in the pool, and three unsuccessful wildcats. Perry County (FIG. 14, AREA 9) Thirteen wells were drilled in Perry County in 1955, all of which were unsuc- cessful wildcats. This is slightly above the average amount of drilling for Perry County. In 1952, when the Tamaroa pool was being developed, 33 wells were drilled. However, the normal annual rate is between five and ten wells. The Tamaroa pool, producing from the Cypress sandstone, made 20,000 barrels of oil in 1955 for a total of 167,000 barrels. There are two Cypress gas wells in the pool, but no gas has been marketed. The only other pool in Perry County is the Craig pool, consisting of one abandoned Trenton well that made about 2,000 barrels of oil. Although results of testing in Perry County have been disappointing, it lies within the area having the best possibilities for oil ac- cumulation. Further exploratory drilling in Perry County is needed to determine its oil potential. Pike County (FIG. 21, AREA 16) The Pittsfield, or Pike County, gas pool was discovered in 1886 and is the second oldest pool in Illinois. Only Litchfield, in Montgomery County, is older. However the gas was not marketed until 1905, b) which time several other pools had been dis covered in the western part of the state. The Pittsfield Gas pool consisted of 68 gas wells covering almost 9,000 acres, nearly half the total acreage of the state's gas pools. The pool was abandoned in 1930 and no production data are available. The pay was in the Silurian. During the 25 years following the aban- donment of the Pike County gas pool, an average of one or two dry holes was drilled annually in the county. In 1955 a second gas pool, Fishhook, was discovered. By the end of the year six gas wells had been completed in the pool, five in Pike County and one in Adams. All were shut in. More wells were being drilled as 1955 ended, but no commercial outlet for the gas had been found. Production is from the Silurian at a depth of about 500 feet. In addition to the gas wells, five dry wild- cats also were completed in 1955. A suffi- cient number of wells were being drilled at the end of the year to indicate that 1956 would be one of Pike County's biggest drill- ing years. Randolph County (FIG. 24, AREA 19) As a result of the discovery of the Tilden pool in 1952, drilling in Randolph County had averaged between 20 and 25 wells an- nually for three years. Only 10 wells were drilled in Randolph in 1955, three of them producers — two in the Tilden pool and one in Baldwin. Seven were unsuccessful wild- cats. Randolph County production is almost en- tirely from the Tilden pool. Since its discov- ery in 1952, Tilden has produced 1,591,000 barrels of oil, including 300,000 barrels dur- ing 1955. The only other oil pool in Randolph County is Baldwin, which has two wells and 60 ILLINOIS STATE GEOLOGICAL SURVEY has produced less than 4,000 barrels of oil, all of it during 1955. The Sparta area produced a little Cypress gas and oil between 1888 and 1900 and again in 1949. Production data are lacking, but quantities of both oil and gas were negligible. The Silurian, which produces in both Tilden and Baldwin pools, is the only commercial pay in Randolph County. Richland County (FIG. 13, AREA 8) Richland County was one of the few im- portant oil producing counties to show a de- crease in drilling in 1955 in contrast to the increase for Illinois as a whole. The number of completions dropped from 122 in 1954 to 113 in 1955. The percentage of successful completions was high, 78 of the 113 wells being com- pleted as producers. Dry holes included 26 pool tests and 9 wildcats. One new pool, Wakefield South, was discovered. At the end of the year only one well had been com- pleted in the new pool and no additional drilling had been started. Most of the production in Richland Coun- ty is from the Clay City Consolidated pool. Estimated production for 1955 in the Rich- land County part of the pool was 2,000,000 barrels, making an estimated cumulative total of 42,000,000 barrels. Excluding the Clay City Consolidated pool, Richland County has produced about 16,- 555,000 barrels of oil, of which 645,000 bar- rels was produced in 1955. This oil has come from 21 pools, including five that pro- duced no oil during 1955 and 10 that pro- duced less than 15,000 barrels each. Most of the oil has come from six pools: Calhoun Consolidated, Dundas East, Olney Consoli- dated, Olney South, Parkersburg Consoli- dated, and Stringtown. Most of the Richland County pools were discovered and developed in the late 1930's or early 1940's. New pool discoveries in the past 10 years have been rare and of minor importance. In 1955 only 12 wildcat wells were drilled. In proportion to total drill- ing, this is only about one-third as high as the rate for the entire state. All 12 were less than two miles from production. Three were successful, discovering Wakefield South and two extensions to pools. The future of Richland as an oil industry county appears to be in the expansion of sec- ondary recovery operations and the develop- ment of new pay zones rather than in the dis- covery of new pools. Only a few wells now produce from pre-Ste. Genevieve pays in the Mississippian, and less than a dozen tests have been made to the Devonian or deeper pays. St. Clair County (Fig. 24, area 19) A new pool, Freeburg South, was discov- ered in St. Clair County in 1955. The dis- covery well had an initial production of eight barrels of oil and 1 1 of water from the Cy- press sandstone. One dry offset well was drilled in December, and a well drilled prior to the discovery of the pool formed a second dry offset. Prospects for further development of the pool are slight. Sixteen wells were drilled in St. Clair County in 1955, 14 of them unsuccessful wildcats, one the successful wildcat that dis- covered Freeburg South, and one a dry hole offsetting the latter well. Dupo remains the only commercial pool in St. Clair County. Discovered in 1928, it had produced 2,810,000 barrels of oil by the end of 1955. The entire pool was shut down late in 1954, but 30 wells were put back into production in 1955 and produced 28,000 barrels during the year. Saline County (fig. 6, area 1) Saline County, which ranked ninth in the state in number of wells drilled in 1954, moved up into second place in 1955. The number of wells completed increased from 140 in 1954 to 335 in 1955. Most of the 1955 drilling was in the Eldorado area, and was discussed above. The 335 wells include 193 oil or gas wells, 87 dry holes, and 75 unsuccessful wildcats. Eight new pools were discovered : Cottage Grove, Eldorado West, Francis Mills South, Harco East, Harrisburg South, Long Branch South, Mitchellsville, and Raleigh South. COUNTY REPORTS 61 At the end of the year none of the new pools had more than two wells except Raleigh South, which had six. Harco East, with two wells completed, had others drilling and looked promising. There were also 13 new extensions to pools in Saline County during the year. Saline County oil production showed a very great increase in 1955, most of it from the Eldorado Consolidated pool. Until 1953 peak production for the county had been 79,000 barrels in 1946. In 1953, when de- velopment of the Eldorado area began, pro- duction was 204,000 barrels. In 1954, it jumped to 791,000 barrels, and in 1955 to 4,099,000 barrels. Total production for the county, from 1941 when the first pool was discovered, through 1955, is 5,551,000 bar- rels. Production was reported for 16 pools in 1955. Two others were abandoned, and two were late-year discoveries that had not yet marketed oil by the end of the year. Ten of the 16 pools reported production for the year of 1,000 to 16,000 barrels. The Eldo- rado Consolidated pool produced 3,523,000 barrels, or about 86 percent of the county's total production. The remaining 1/2 million barrels came from the five other biggest pools in the county: Eldorado East, Dale Con- solidated (formerly West End), Harrisburg, Raleigh, and Raleigh South. Both drilling and production rates de- creased in the latter part of 1955, but should remain comparatively high in 1956, although below the 1955 level unless a new Eldorado area of production is discovered. Sangamon County (FIG. 18, AREA 13) At the end of 1954 hopes were high for the discovery and development of oil pools in Sangamon County during 1955, although only three oil wells had previously been com- pleted there. Two of these had been drilled in the Roby pool, one in 1949 (abandoned in 1951) and one in 1954. The third well was the discovery well of the New City pool, drilled in December of 1954, when explora- tory drilling moved westward from the rap- idly developing Decatur-Mt. Auburn area into Sangamon County. In 1955 two more oil wells were added to the New City pool, one new pool (Glen- arm) was discovered, and four wells in the Edinburg West pool (a Christian County pool) were drilled in Sangamon County. In 1955 Sangamon County marketed its first oil through regular pipeline outlets. The Edinburg West wells produced 31,000 bar- rels and the New City pool 28,000, making a 1955 total of 59,000 for the county. There was no drilling in Sangamon Coun- ty in 1953. In 1954, seventeen wells were drilled, and in 1955 the number increased to 49. Only seven were successful ; nine were dry holes in pools, and 33 were unsuccessful wildcats. Sangamon County is outside the area of best prospects for oil. All production so far has been from the eastern part of the county, within five miles of Christian County. It remains doubtful that new pools will be dis- covered to the west or north. All Sangamon County production is from Silurian limestones. There is no Mississip- pian or Pennsylvanian production in or near Sangamon. Shelby County (FIG. 19, AREA 14) Although Shelby County lies within the deep part of the Illinois basin where pro- ductive possibilities are best and most of its surrounding counties have at least one good pool and good production records, Shelby drilling and production both have been dis- appointing. Four wells were drilled in 1955, all of them dry wildcats. This is about normal for Shelby County. In 1946, completions reached a high of 46 for the year, including nine pro- ducing wells. Only 26 producing wells ever have been drilled in Shelby County, seldom more than two in a year, and none since 1952. Three pools, Stewardson, Shelbyville, and Shelby ville East (abandoned) have Aux Vases production only, Clarksburg has Bethel only, and Lakewood has both. Lakewood is the largest pool in Shelby County. It has accounted for about 225,000 62 ILLINOIS STATE GEOLOGICAL SURVEY barrels of the 423,000 barrels of oil pro- duced in the county, 11,000 of them in 1955. Stewardson, the oldest pool in the county, produced 9,000 barrels in 1955 for a total of 152,000 barrels. Shelbyville and Shelby- ville East have produced 27,000 barrels, less than 2,000 of it during 1955, and Clarks- burg about 19,000 barrels, including about 2,000 in 1955. Wabash County (FIG. 8, AREA 3) Although Illinois as a whole showed big increases in both drilling and production in 1955, Wabash County showed fairly large decreases in both. Wabash is one of the most densely drilled counties. Only 144 wells were drilled in 1955, compared with 203 in 1954. Of the 144 wells, 73 were oil wells, 61 were dry holes in pools, and only 10 were wildcats, all of them less than two miles from production. No successful wildcat was drilled in Wabash County in 1955 and new pool discoveries are certain to be rare in the future because of the comparatively small amount of un- tested acreage remaining. Wabash County dropped from fifth place in the state in drilling in 1954 to tenth place in 1955. The future of Wabash County oil production will depend largely on devel- oping new pay zones and expanding secon- dary recovery operations. Production decreased from an estimated 3,623,000 barrels in 1954 to an estimated 3,214,000 barrels in 1955. About half the county's production is from the New Har- mony Consolidated pool, which extends into White and Edwards counties. The break- down of production figures among the three counties is estimated. Total production for the county is about 65,875,000 barrels. Most of the 73 new oil wells drilled dur- ing 1955 were in the Allendale, Mt. Carmel, and New Harmony Consolidated pools. The Mt. Carmel pool showed an increase in pro- duction from 318,000 barrels in 1954 to 452,000 barrels in 1955. Production in the Allendale pool increased from 539,000 bar- rels to 570,000 barrels. The Allendale pool extends into Lawrence County, but no attempt has been made to divide the produc- tion between the counties. Other pools in the county had little or no drilling and most showed a decrease in production. Washington County (fig. 14, AREA 9) Washington County was among the coun- ties showing the largest increases in drilling in 1955. The number of wells drilled in- creased from 80 in 1954 to 131 in 1955, the second largest number in the history of the county. High point in Washington County drill- ing was the discovery of the Cordes pool in 1939, which resulted in the drilling of 133 wells that year. Discovery of the Irvington pool the following year kept drilling up for a time, after which it dropped off to a low of 10 wells, all dry, in 1950. Since 1950 Washington County has shown a fairly con- sistent increase in drilling and an improved rate of production. More important than the increase in drill- ing in 1955 was the increased percentage of successful completions. In 1954 less than one-third of the new wells were producers; in 1955, 67 out of 131, or more than half, were successful. The Dubois Consolidated pool is responsible for much of the new drill- ing, 42 of the 67 producing wells are in that pool. Washington County pools produced 1,- 020,000 barrels of oil in 1955, making a cu- mulative production of 14,741,000 barrels. Most of the oil came from the five biggest pools, but a dozen small ones each made from less than 1,000 up to 23,000 barrels. Cordes, the oldest and largest pool, pro- duced 325,000 barrels in 1955 to bring its total production up to 7,027,000 barrels, all from the Bethel sandstone. The Irvington pool ranks second. Its pro- duction until 1954 was from the Bethel sand- stone and a few Cypress and Devonian wells. In 1954 and 1955, 23 Cypress and three De- vonian wells were added to the pool. Produc- tion increased a little in 1954 and then spurted to 247,000 barrels in 1955. Total production for the Irvington pool is 5,747,- 000 barrels. COUNTY REPORTS 63 The Dubois Consolidated pool was dis- covered in 1939 and "rediscovered" in 1955. Up to the end of 1954, 21 oil wells and eight shut-in gas wells had been drilled. Annual production for the pool ranged from 9,000 to 36,000 barrels of oil. In 1955, 42 oil wells were drilled, twice as many as in the previous 16 years of the pool's existence. Production jumped to 147,000 barrels for 1955, boosting the total production to 431,- 000 barrels. The eight gas wells, drilled in 1947 and 1948, were still shut in, but pros- pects for marketing the gas seem to have im- proved. The gas is in the Cypress sandstone and the oil in the Cypress and Bethel sand- stones. The Irvington North pool, only three years old, has produced 360,000 barrels of oil, 134,000 during 1955. The Cypress sandstone was opened up as a new pay in 1955. Previously all production had been from the Bethel sandstone. Beaucoup South produced 80,000 barrels of oil from the Bethel sandstone in 1955, bringing its total production up to 336,000 barrels. The 64 dry holes drilled in Washington County during the year included 27 in pools and 37 wildcats. Wayne County (FIG. 12, AREA 7) Although drilling in Illinois increased 20 percent in 1955 over the 1954 rate, Wayne County drilling decreased 40 percent — from 419 wells completed in 1954 to 252 in 1955 — the biggest decrease for any major oil pro- ducing county. Wayne had been among the three top drilling counties from 1941 through 1954, frequently ranking first or sec- ond. In 1955 Wayne dropped to fourth place, far behind White and Saline counties, but only three wells behind third-place Law- rence County. There is no reason to anticipate an in- crease in drilling in Wayne County in 1956, but it probably will regain its place among the top three counties, as drilling was de- creasing in Saline County by the end of 1955. The 252 wells completed in Wayne Coun- ty in 1955 included 166 oil wells, 65 pool dry holes, and 21 unsuccessful wildcats. No new pool was discovered during the year, but five successful wildcats opened up exten- sions to pools. No new pays were discovered and no deep tests made. Over half the oil produced in Wayne County has come from the Clay City Consoli- dated pool, which has produced an esti- mated 73,600,000 barrels of oil in Wayne County, including 3,600,000 barrels in 1955. County production excluding Clay City Con- solidated was 3,233,000 barrels in 1955, mak- ing a cumulative total of about 56,500,000 barrels. Wayne County has the second highest number of pools, being surpassed only by White County. During 1955, 29 pools in Wayne County produced oil; four other pools previously had been abandoned. Nine Wayne County pools have produced over a million barrels of oil each. These in- clude, besides Clay City Consolidated, John- sonville Consolidated with 29,467,000 bar- rels, Aden Consolidated with 7,573,000 bar- rels, Goldengate Consolidated with 4,186,000 barrels, Barnhill with 3,704,000 barrels, and four pools with production between 1,000,000 and 2,000,000 barrels— Ellery Consolidated, Keenville, Coil, and Half Moon. Wayne County in 1955 remained among the leading producing counties, although its total production is still greatly exceeded by that of half a dozen counties that had pro- duced large quantities of oil before Wayne County development was well established. White County (FIG. 7, AREA 2) In 1955 White County ranked first in the state in both drilling and production. It had 478 wells completed, almost one-eighth of Illinois' total number of completions (3,885), and produced approximately 10,000,000 bar- rels of oil, or almost one-eighth of the state's total production (81,131,000 barrels). In cumulative production White County is surpassed by Lawrence and Crawford counties, which had production 30 years earlier, and Fayette and Marion counties, where Louden and Salem Consolidated were at peak production around 1940 before 64 ILLINOIS STATE GEOLOGICAL SURVEY White County development was well under- way. White County has surpassed all four of these counties in annual production dur- ing recent years. The 478 wells drilled in 1955 include 304 producing wells, 142 dry holes in pools, and 32 wildcats. One new pool, Centerville Northeast, was discovered ; only one small well had been completed in the pool at the end of the year. About half of the new producing wells were in the White County parts of Roland Consolidated, Maunie North Consolidated, and New Harmony Consolidated pools. The rest of the new wells were widely distrib- uted among White County's 29 producing pools. Approximately half of White County's production comes from two pools : the White County portions of Roland Consolidated and New Harmony Consolidated. This produc- tion in 1955 was estimated at almost half a million barrels. The 27 other pools in the county produced 5,051,000 barrels of oil in 1955. Seven pools (Phillipstown Consolidated, Maunie North Consolidated, Maunie South, Herald Consolidated, Centerville East, Mill Shoals, and Storms Consolidated), each of which produced between 300,000 and 1,000,- 000 barrels for 1955, had a combined pro- duction of about 3,750,000 barrels; the county's remaining 1,300,000 barrels was produced by 20 smaller pools. White is one of the most closely drilled counties. The present rate of drilling can- not continue many years more, but at the end of 1955 no decline was yet apparent. Williamson County (FIG. 23, AREA 18) As a result of the very successful drilling in Saline County in 1955, Williamson Coun- ty had its biggest year of drilling. Fifteen wells were drilled, one a dry hole in the Marion pool and the others unsuccessful wild- cats. The only oil so far produced in William- son County has been a few hundred barrels from an Aux Vases sandstone well near Marion. However, there is good Aux Vases and Ste. Genevieve production in four pools within three miles of the northeast corner of Williamson County in Franklin (Thomp- sonville pool) and Saline (Dale Consoli- dated, Harco, and Harco East pools) coun- ties. Most of the drilling in Saline County in these three pools was done in 1954 and 1955. If they continue to develop toward Williamson County, it is reasonable to an- ticipate continued exploratory drilling in Williamson County. Other Counties Unsuccessful wildcat wells were drilled during 1955 in 16 counties that have had no oil or gas production. Four wells were drilled in Jersey County, three each in Kankakee and Schuyler counties, and two each in Iro- quois, Johnson, and Mercer counties. One unsuccessful wildcat was drilled in each of the following 10 counties: Cass, Champaign, Fulton, Hardin, Livingston, Logan, Piatt, Pope, Union, and Vermilion. OIL PRODUCING STRATA 65 OIL PRODUCING STRATA OF ILLINOIS (SEE FIG. 3, PAGE 23) Oil production from sandstones in the upper two groups of Pennsylvanian age, the McLeansboro and Carbondale groups, is very minor ; Tradewater and Casey ville sandstones have yielded about one-sixth of the state's oil. The sand grains in Pennsylvanian sand- stones are a little coarser and less well rounded than those lower in the section, but the majority are classed as subangular and fine to medium (averaging perhaps l/60th of an inch in diameter). The sandstones are gen- erally dirtier than the pre-Pennsylvanian sandstones; they have more mica flakes, more clay, and in general more minerals other than quartz. Some of these sandstones, particu- larly in the upper part of the Pennsylvanian, rank technically as subgraywackes rather than as high-quartz sandstones. Porosity is quite low in the Pennsylvanian sandstones in general but averages about 18 percent in the cleaner sandstones, including most of the oil reservoirs represented in the pools of the Southeastern Illinois field. Occasional spots in the basal Pennsylvanian beds have very high porosity — among the highest of any Illi- nois rocks — with values of about 30 percent. Permeability is in general moderate. The original low gas content of many Pennsyl- vanian oils resulted in rather low primary re- covery and together with shallow depth makes the Pennsylvanian reservoirs particularly at- tractive for secondary recovery. Despite the fact that little oil has been found in the Penn- sylvanian in 1954 and other recent years, Pennsylvanian production has been increas- ing, owing to the development of secondary recovery projects. Chester sandstones have to date produced more than one-half of Illinois' oil and the proportion is mounting. The higher sand- stones, the Degonia, Clore, and Palestine, are of little consequence and are productive only in the region of the lower Wabash Val- ley. The middle sandstones, Waltersburg, Tar Springs, and Hardinsburg, are more productive with some very prolific pools, but significant accumulations are confined to a relatively small area in the southern and east- ern oil counties. '1 he Jackson sandstone ot Indiana and Kentucky barely enters Illinois. The lower Chester sandstones in general, and the Cypress in particular, are produc- tive nearly throughout the oil country and are the sinews of the Illinois oil industry. Chester sandstones are physically quite similar to each other, except for the Aux Vases. The sand grains are largely very fine to fine (averaging about l/100th of an inch in diameter) and subrounded to subangular. Mica, clay, and minerals other than quartz are less common than in the Pennsylvanian. Probably all productive sandstones are tech- nically quartzose ; a few tight, dirty, shaly sandstones are subgraywackes. Porosity is commonly around 20 percent and ranges in the productive sections from about 15 percent to about 25 percent. The Aux Vases west of the principal meridian is similar to the other Chester sand- stones but carries little oil. Where the Aux Vases is most prolific, in the central part and up the east flank of the basin, many of its properties contrast sharply with those of more typical Chester sandstones. The sand grains are smaller, in the very fine sand and coarse silt range, about 1/150 inch in diameter, and are well sorted. That is, there is relatively little difference between the smallest grains, about 1/200 of an inch, and the largest, about 1/100 of an inch. The fine grain is the key to most of the distinctive character- istics of the Aux Vases. Smaller grains tend to be less well rounded and have more non- quartz minerals than larger grains from the same source. A slight "peppering" of pink, green, and dark grains is characteristic of the Aux Vases under the usual oil-field binoc- ular microscope, but careful laboratory meas- urements are needed to show its greater angu- larity. Almost all oil sands are preferentially water-wet, a film of water covering each sand grain. Even in the oil-bearing part of a reservoir, oil fills only the central parts of the pores. These water films occupy about 30 percent of the total porosity in the oil zone of most Chester sandstones; the water content of oil-bearing Aux Vases with smaller grains (and thus smaller but more numerous pores) is about 50 percent of the total porosity. The total porosity of the fine-grained and well- 66 ILLINOIS STATE GEOLOGICAL SURVEY sorted Aux Vases is a bit higher, averaging perhaps 22 percent, with a range of 15 per- cent to 30 percent, as compared to an average of 20 percent or less for other Chester sands. The high water content makes oil more dif- ficult to recognize than in other sandstones, and Aux Vases production was sometimes passed by during the earlier stages of explora- tion. Fine-grained reservoirs react spectacu- larly to hydraulic fracturing. Although the Aux Vases has produced less oil in the past than the Benoist (Bethel) and Cypress sands, it is probably leading in current production and is by far the most important single hori- zon in current development. Chester limestone production is insignifi- cant, although a little oil has come from limestones in several formations. The most prolific reservoirs in the lower Mississippian rocks are oolitic limestones, which have produced one-fifth of Illinois' oil. Most important is the McClosky zone, which consists of porous lenses of oolitic limestone in the Fredonia member of the Ste. Genevieve formation. The oolitic Ohara or Lower Ohara pay zone in the Levias member and oolitic streaks at the horizon of the Rosi- clare member of the Ste. Genevieve are quite similar to the McClosky, as are oolites in the St. Louis and Salem formations. Oolitic limestones are made up of small balls, about 1/25 of an inch in diameter, of chemically deposited layers of calcium carbon- ate. The layers, like onion rings, form around a nucleus — a sand grain, a silt grain, a small fossil, a fragment of rock, or a speck of dust. In much oolitic limestone the indi- vidual oolites are enclosed in fine-grained limestone and the rock is non-porous. The pay zones differ in having some free pore space between the oolites. There are minor differences between beds; Ohara oolites are typically large, about 1/20 of an inch in di- ameter; St. Louis oolites are small, about 1/50 of an inch; Rosiclare oolites tend to have fair-sized sand grains for centers ; Salem oolites include many microscopic fossils cov- ered with only thin rims of chemically pre- cipitated calcium carbonate. The typical oolite reservoir has about 15 percent porosity, less than most sandstones. Permeability, the rate at which a fluid can flow through rock, is relatively high, so oil production tends to decline rather rapidly after a spectacular initial flush period of a few months. The water content in the oil zone is low, around 10 to 20 percent. Hy- draulic fracturing is not particularly helpful, but in most instances productivity can be in- creased greatly by acidizing. Waterflooding of the oolitic reservoirs is simple, but as pri- mary recovery is generally high, less oil is left for secondary recovery than in the sand- stone reservoirs. The two lower Mississippian productive sandstones have quite different characteristics. The Rosiclare zone is a typical oolite in the southern and eastern oil counties, with occa- sional sand grains accompanying the oolites. Toward the northwest the sand grains be- come more numerous and production is ob- tained from a slightly limy sandstone, a bit coarser than the average Chester sandstone. Present over much of the northern part of the basin is the Carper, an extremely fine grained sandstone, in most places actually a siltstone. It has had occasional oil shows, but at only one spot in Clark County has it been open enough to produce significant amounts of oil. Devonian production comes from sand- stones, limestones, dolomites, and cherts, and is difficult to characterize briefly. The sand- stones, at three or four different horizons, produce only a fraction of a percent of Illi- nois' total oil. They contain relatively nu- merous large well-rounded grains 1/50 of an inch or more in diameter, although the aver- age grain diameter may be little greater than that of Chester sandstones. The Devonian dolomites, cherty dolomites, and dolomitic limestones are more prolific, producing perhaps 5 percent of the Illinois oil. The pure dolomites are composed of par- tially interlocked "sugary" lozenge-shaped crystals of the mineral dolomite, calcium magnesium carbonate. The crystals are gen- erally 1/400 to 1/100 of an inch in diameter. Porosity between the crystals is about 20 to 25 percent in pure dolomites but less where only part of the rock is dolomite. Where extensive systems of large cavities, or vugs, are present, phenomenal initial production OIL PRODUCING STRATA 67 has resulted. The existence of three types of porosity — that between the crystals, in vugs, and in fractures — has made the planning of secondary recovery programs difficult. Silurian production, approaching one per- cent of Illinois' total, is from two quite dif- ferent types of rock. Much Silurian dolomite in the southern part of Illinois is too fine- grained for production, but occasional streaks, generally purer, are coarse enough to ap- proach the lower limit of productive dolo- mite rock. As might be expected, this fine- grained rock reacts favorably to fracturing but poses problems in waterflooding. Silur- ian "coral" reefs in the northern part of Illi- nois are dolomitized, porous, and very perme- able. In the oil area the reefs are limestone with very low porosity but have a few vugs and an extensive fracture system that may contain oil. Silurian reef rock produces oil from Marion County westward. [ntergranular porosity, between relatively large (in the 1/10-inch range) crystals of calcium carbonate and fossil fragments, is of greatest importance in the Trenton lime- stone, which has produced less than one per- cent of Illinois' oil. The limestone generally is quite dense and its porosity is in the 5 to 10 percent range, even in the scattered produc- tive streaks. Porosity and permeability in- crease westward across the western part of the oil area, and fractures are of considerable im- portance in the westernmost pools. Acidiz- ing is a common completion practice, and it seems likely that hydraulic fracturing will be of relatively little help. 68 ILLINOIS STATE GEOLOGICAL SURVEY Table 9. — Illinois Oil and Gas Pools* January 1, 1956 Pool: County Ab Lake: Gallatin Ab Lake West: Gallatin. . . .
