OIL AND GAS DEVELOPMENT IN ILLINOIS IN 1940*

By

Alfred H. Bell and George V. Cohee

Illinois produced 146,788,000 bbl. of

oi! in 1940, or nearly 11.0 per cent of the

total for the United States, and rankedfourth among the oil-producing states.

Its production was only slightly less than

that of Oklahoma, which produced 11.5

per cent of the national total. Illinois'

production in 1940 represents an increase

of 55 per cent over the previous year,

when it amounted to 94,912,000 barrels.

The development of the Devonianlimestone in the Salem and Centralia

fields is largely responsible for the increase

in production during 1940. Production

from the Devonian limestone in these twofields was estimated to be 36,698,000 bbl.,

or 25 per cent of the state's total pro-

duction (Table 1). The increase in pro-

duction during June, when the state's

daily average production attained a peakof 518,200 bbl. for the week ending June29, was due to the Devonian production

at Centralia (Fig. 1). The initial produc-

tion of the best Devonian wells in the

Centralia field was as high as 12,000 bbl.

in 24 hr. Dailv average production in

Illinois for 1940 was 400,000 bbl. of oil,

but actually daily production fluctuated

widely during the year. At the beginning

of 1940 dailv production was approxi-

mately 330,000 bbl. During the first half

of the year it increased irregularly to the

peak in June mentioned above and as the

prolific Devonian producing areas were

drilled up, the state's daily production

declined rapidly during July and contin-

*Reprinted. with certain additions, from Trans. A.I.M.E.vol. 137. pp. 274-298, 1941.

ued to decline, although more slowly,

until the end of the year, when the daily

production was approximately 325,000bbl. The daily average production perwell in the new fields at the end of theyear was approximately 40 bbl. (Fig. 1).

Oil from the Devonian was also pro-

duced in the Bartelso field, ClintonCounty, the Sandoval field, MarionCounty, and the Irvington field, Wash-ington County, bringing the estimatedtotal production from the Devonian lime-

stone to about 26 per cent of the state's

total production. The remainder was ob-tained largely from the Mississippiansystem.

About 2 per cent of the total was fromPennsylvania!! and Ordovician strata.

The decline in the Devonian limestoneproduction has been so rapid that the

1941 output from this system will proba-bly be only a small fraction of that of 1940unless large new reserves are discovered.

The "Trenton" (Ordovician) limestonehas been tested in two wells in the Cen-tralia field and both were small oil pro-

ducers at a depth of about 4000 ft. The"Trenton" also was found productive in

the Salem field at a depth of 4500 ft.

(Table 5). The initial production of the

discovery well, which was completedshortly after the end of the year, was 130

bbl. on pump. Other wells drilled early in

1941 had initial productions averaging172 barrels.

The outlook for 1941 is for a continu-

ation of drilling activity in Illinois, but at

a declining rate (Fig. 1, upper curve).

The most active area at the end of 1940

was in the deep basin area in Wabash,Edwards, White, and Hamilton Counties.

During 1 040, the wells completed num-bered 3829, of which 3064 were oil pro-

ducers, 16 were gas producers and 749

were dry holes (Table 2). Of the total,

523 are classified as wildcat wells and of

these 48 (or 9.2 per cent) were successful

in obtaining production; 30 discovered

new fields and 18 discovered extensions

to known fields (Table 4 and Fig. 2).

The sequence of rock strata and relative

positions of the producing zones are

shown in figure 3.

The results of an investigation to ascer-

tain the reason for the locations of as

many as possible of the wildcat wells are

set forth in the accompanying table.

Of the 523 wildcat wells, the 303 knownto have been located by scientific methodswere 15 per cent successful whereas the

remaining 220 were only 1.3 per cent

successful. The total footage of wildcat

wells drilled in 1940 was 1,092,011 ft., of

which a total of 121,342 ft. was drilled in

successful wildcat wells.

The number of producing wells in the

new fields increased from 5042 at the

beginning to 7965 at the end of 1940.

There were 361 drilling operations in

the state at the end of the year. As ofDec. 31, 1940, of this number 248 were in

the new fields. The area proved for pro-

duction in th; new fields increased from54,210 acres at the beginning of the year

to 78,040 acres at the end, an increase of

23,830 acres, of which 6480 acres are in

the 30 fields discovered in 1940 and the

remainder, 17,350 acres, in extensions to

known fields.

Explanation of Table 1

The ("eld is the unit in table 1. Each space

may represent one of four possibilities; either

it is not applicable to the particular field, or the

proper entry is not determinable, or the properentry may be determinable but is not deter-

minable from data available to the author, or

the proper entry is determinable. Spaces that

are not applicable are left blank; in spaces

where the proper entries are determinable fromdata available to the author, y is inserted; y im-plies a hope that in some future year a definite

figure will be available; x indicates that dataare not known.The entry of a is a positive declaration.

The quantity of gas includes gas sold or

otherwise marketed. Gas blown into the air,

burned as flares or otherwise wasted is not in-

cluded.

Under the columns on "Depth," the averagedepth to the top of the productive zone and to

the bottom of the productive well, when sub-

tracted, does not necessarily give the approxi-mate thickness of the productive zone.

In classifying wells as to producing methods,all wells that are not "flowing" are entered in

the column headed "Artificial Lift."

Footnotes to Column Headings—Table 1

a The old Southeastern fields are listed in

geographic order from north to south ; all others

are listed alphabetically by counties.

Areas where both oil and gas are produced,unless gas is marketed outside the field, are

included in the column headed "Oil."

Wells producing both oil and gas are classi-

fied as "Producing Oil." Gas wells are those

producing gas, but include those producing wetgas, from which casinghead gasoline may beproduced.

On the basis of posted prices, the total

value ot the oil produced in 1940 was ap-

proximately 8158,746,200. The average

price calculated from the available dataon production and prices tor the state was$1.05 per barrel to Aug. 21 and 81-15 per

barrel tor the remainder ot the year.

In 1940, a total of 9,573,034 ft. of hole

was drilled in the state. Of this amount7,922,464 ft. was drilled in producingwells. If an average cost of $3.00 per foot

is assumed, the total investment in drill-

ing was 828,719,102, including both pro-

ducing wells and dry holes. The averagedepth ot all wells drilled in the state in

1940 was 2500 ft., which is almost 500 ft.

deeper than a year ago. This difference is

accounted tor in the development of deep-er "pays" in proven fields and exploration

in the deep basin area.

The average initial daily production ofthe oil wells was 573 bbl., an increase of195 bbl. per well over last year's figure.

The increase is due to the large Devonianwells in Salem and Centralia fields.

Pipe Lines and Refineries

Pipe-line construction in Illinois wasless extensive in 1940 than in the previousyear. The construction of crude-oil lines

was principally to provide outlets for thenew fields in Wabash, White and Hamil-ton Counties. It is estimated that thetotal daily capacity of the crude-oil lines

in the state is approximately 550,000 bbl.

Pipe-line construction in Illinois during1940 was as follows:

Early in 1940 the capacities of mostrefineries in the state were enlarged in

order to handle the increased supply ofIllinois crude oil. The Wood River Oil andRefining Co. constructed a new refinery

near Wood River, 111., with a daily capac-ity of 7500 bbl. This brings the total

capacity of all refineries in the state upto 258,750 bbl. daily, an increase of 65,400bbl. over the capacity a year ago.

Owing to the decline in production dur-ing the latter part of 1940, and the in-

creased price of crude oil, eight small

refineries having a capacity of 2000 bbl.

or less per day, located near the new fields

in southern Illinois shut down operations.

At the end of the year 21 of the 29 re-

fineries in the state were in operation.

X. ITUJUL GAS 21

During the year, 79.5 per cent of Illi-

nois' crude-oil production was sent to re-

fineries in the Central refining district

(Illinois, Indiana, Kentucky, Michigan,and western Ohio), 16.0 per cent to the

Appalachian refining district (eastern

Ohio, western New York, western Penn-sylvania, and West Virginia), and 4.5 percent to the Atlantic seaboard. For Decem-ber 1940 the runs to stills in the Centraland Appalachian refining districts were23,196,000 bbl. Of this amount, Illinois

production was 44.7 per cent. Stocks ofcrude petroleum on hand in Illinois onDec. 31, 1940, were 13,944,000 bbl., as

compared with 12,983,000 bbl. on Dec.

31, 1939. Stocks of refined products in the

Central and Appalachian refining dis-

tricts compared with the previous yearare as follows:

Production of Natural Gas

Natural gas was marketed from the

Avers and Russellville gas fields and the

Salem and Louden oil fields during 1940.

The Ayers gas field, in Bond County,produced 13,777,300 cu. ft. of gas in 1940,

which brings the total production from

the field to 194,403,400 cu. ft. Production

is at an average depth of 940 ft. from the

Aux Vases sandstone of the Chester series.

The field has a productive area of 325

acres and the average thickness of the

"pay" is 5 ft. Seven wells are producing,

none of which was new in 1940. They sup-

ply gas to the city of Greenville, Illinois.

Continued development during 1940 in

the Russellville gas field in northeastern

Lawrence County increased the produc-

tive acreage to 1600 acres, which is 680acres more than a year ago. As of Jan. 1,

1941, there were 41 producing wells in the

field. Production is from the Buchanansand of lower Pennsylvanian age, whichis encountered at a depth of 1090 ft. Theaverage thickness of the "pay" is 10 ft.

The total production for the field to the

end of 1940 was 1,955,500,000 cu. ft.,

890,400,000 cu. ft. being produced in 1940.

1 The figures for total production are from the U. S.Bureau of Mines; other figures are from various sources.

2 Includes Devonian production at Sandoval and Bar-telso.

Natural-gas production for 1940 in theLouden field is estimated to be approxi-mately 11 billion cu. ft. The average dailyproduction in December 1940 was esti-

mated to be 28,000,000 cu. ft. Of this

amount 10,000,000 cu. ft. of gas wasprocessed in the Carter Oil Company'stwo natural-gasoline plants. There is ashrinkage of 2,800,000 cu. ft. of gas in theplants, which is accounted for in thenatural gasoline, butane, and propaneproduced and in fuel for plant operation.The total yield of natural-gasoline butaneand propane is approximately 3.2 gal. perthousand cubic feet of "wet" gas. Twoand one-half million cubic feet of the"dry" residue gas was injected daily intothe producing sands through 63 inputwells.

The Town of St. Elmo, 111. and local

industries are supplied by the MonarchGas Co. with this residue gas from thenatural-gasoline plants and from a leasein the field that is producing "dry" gasfrom a basal Pennsylvanian sandstone,encountered at a depth of 1071 ft. Theamount of residue gas marketed during1940 was 215,376,000 cu. ft. and theamount of gas marketed from the leasewas 13,575,000 cu. ft. The Monarch GasCo. constructed a pipe line to Browns-town, 111., to supply the town with naturalgas starting about Jan. 1, 1941.

EXPLORA TION METHODS 23

In the Louden field during December1940, approximatey three million cubic

feet of "wet" gas was used daily in field

operations and the remaining 15,000,000

cu. ft. was burned in flares.

The production of natural gas with the

oil in the Salem field for 1940 is estimatedto be 71 billion cu. ft. The average daily

production for December is estimated to

be 117,000,000 cu. ft. Of this amount 52

million cu. ft. of gas was processed daily

in the three natural-gasoline plants in the

field. The plants are owned and operatedby the Texas Company, Warren Petrole-

um Co., and the Sunflower Natural Gaso-line Co., The total yield of natural gaso-

line, butane, and propane is approxi-

mately 2.6 gal. per thousand cubic feet

of "wet" gas.

The city of Salem, 111., is using residue

gas from the Sunflower Natural GasolineCompany's plant and the Warren Petro-

leum Company's natural-gasoline plant

in the Salem field. The city began to use

the gas about Oct. 1, 1940, and is taking

approximately 350,000 cu. ft. daily.

A small amount of the gas produced in

the field is used in field operations and the

remainder of the "wet" gas and the" dry"gas not marketed or returned to the pro-

ducing formation is burned in flares.

Xatural-gas production in the Centralia

field during 1940, which was principally

from the Devonian limestone, was esti-

mated to be approximately 10 billion cu.

ft. Gas production in the field was great-

est during the development of the Devon-ian limestone early in 1940, when the

gas-oil ratio was 2000 cu. ft. per barrel.

During December 1940, it was estimatedthat the gas production was approximate-ly 4,000^000 cu. ft. daily. Natural gas

from the Devonian limestone is used in

repressuring the Cypress and Bethel sand-stones on two leases in the field. In three

input wells 100,000 cu. ft. of gas daily is

injected in the Bethel sandstone and60,000 cu. ft. of gas is injected daily in the

Cypress sandstone through one input well.

The total volume of gas produced in

the Storms field, White County, during

1940 was estimated to be approximately22 billion cu. ft. The daily productionduring December was estimated to be

18,000,000 cu. ft. This is a considerable

decrease from the beginning of the year,

when the production was estimated to be

100,000,000 cu. ft. daily. As of Jan. 1,

1940, there were 130 producing wells in

the field, three of which were strictly gas

wells that were shut in. The initial pro-

duction of gas produced with the oil in

some wells completed in the field during1940 was as much as 30,000,000 cu. ft.

daily. As yet no gas has been marketedfrom the field.

Gas production in the Central basin

fields in Jasper, Richland, Clay, Wayne,and Northwestern White Counties has de-

clined during 1940, particularly in the

older fields such as Clay City and Noble.The total gas production during 1940 for

this area is estimated to be approximately16 billion cu. ft. with a daily productionof approximately 45,000,000 cu. ft. Noneof the gas is marketed, but much is usedin lease operations and heat treatment of

the oil.

Natural gas was discovered in the W. N.Lee et al.-Thomas Sharf No. 1, C. NWXSWX SEX sec. 27, T.7 N., R.4 W., BondCounty, on the Panama dome, which is a

structure mapped on coal No. 6.1 The gas

sand, which is of lower Pennsylvanianage, was found at a depth of from 555 to

595 ft. The initial production of the well

was 500,000 cu. ft. A well was drilled off-

setting the Sharf No. 1, which had an es-

timated initial production of 1,000,000 cu.

ft. More wells are to be drilled in the

area in an attempt to obtain a sufficient

supply of gas for marketing.

Natural Gasoline

Natural gasoline is produced at some46 plants in the old southeastern field, at

three plants in the Salem field and at twoplants in the Loudon field. According to

the U. S. Bureau of Mines,- Illinois pro-

duced 21,432,000 gal. of natural gasoline

in 1940. In January, the amount was998,000 gal.; the other months ran from1,062,000 to 3,461,000 (December). Sta-

tistics on the production of propane andbutane in 1940 are not yet available.

Exploration Methods

Subsurface geology and geophysics,

largely the reflection seismograph, are still

the principal methods used in guiding ex-

ploration and development. Most of the

seismograph activity during 1940 was in

southern Illinois in White, Hamilton,Franklin, Williamson, Saline and Gallatin

Counties. The number of seismographparties operating in the state throughoutthe year was as follows:

Gravimeter exploration was conductedby at least three major companies duringthe year and a number of magnetometersurveys were made in the Illinois basin.

Several companies and individuals haveemployed geochemical and electrical ex-

ploration methods in many areas of south-ern Illinois. The exploration work wasdone principally by four companies withdistrict representatives in the state. Thesemethods have been used for both recon-

naissance and detail studies.

Deep Tests during 1940 (Table 5)

The St. Peter sandstone was tested in

the Carlyle, Mattoon, Sandoval and Cisnefields but was not found productive. In

the Carter Oil Company's Seaman No. 1

well in the Mattoon field, there was a showof oil at a depth of 4690 ft. in the Glen-wood sandstone overlying the St. Petersandstone. No shows of oil were reportedbelow the McClosky limestone in the

Pure Oil Company's Stella Billington No.3, drilled in the Cisne pool. This well,

which is the deepest well drilled in the

state to date, was abandoned at a depthof 7207 ft. The top of the St. Peter sand-stone was encountered at a depth of 7114ft. The sandstone was so hard and " tight"

that many drilling bits were used in the

thickness penetrated.

Another St. Peter test of considerableinterest was the Texas Company's TateNo. 21 well in the Salem pool, which wascompleted early in 1941. The total depthof the well was 5655 ft., 405 ft. below the

top of the St. Peter sandstone, which wasreached at a depth of 5250 ft. The St.

Peter was found to be 167 ft. thick. Noshows were reported below the "Trenton"limestone.

The "Trenton" limestone was testedin the Fairman, Centralia and Salem fields

and was found productive in the last twomentioned. Production from this forma-tion was small in the Centralia pool butwas somewhat better in the Salem pool.The Devonian limestone was tested in

Albion, West Liberty, Patoka, NorthAden and Phillipstown fields, but it wasnot productive.

There is a revived interest in the possi-

bility of deeper production in the oldAllendale field in northeastern WabashCounty. Early in 1941 a well was com-pleted in the Bethel sandstone at a depthof 2,011 feet which had an initial produc-tion of 250 barrels on pump. The well wasdrilled in one of the areas recommendedfor deeper testing by the Illinois Geologi-cal Survey. 3 Other wells have since beencompleted in the Bethel sandstone in this

area.

Secondary Recovery

Repressuring.—Repressuring of theBethel and Aux Vases sandstones of theChester series and the McClosky lime-

stone of the lower Mississippian systemin the Salem field was continued by theTexas Company. At the end of the yearabout 2.5 million cu. ft. of" dry" gas daily

was being injected into 32 gas-input wells.

Thirteen new input wells were drilled in

1940 and eight formerly producing wells

were changed to gas-input wells.

Additional gas-input wells were drilled

by the Carter Oil Co. for its repressuring

project in the Louden field during 1940.

On Dec. 31, 1940, there were 63 input

wells in operation in the Cypress, PaintCreek "Stray" and Bethel sandstones of

the Chester series. The total daily amountof "dry" gas returned to the producingformations was 2.5 million cubic feet.

Repressuring of the Cypress and Bethel

sandstones in the northern part of the

Centralia field was begun during the lat-

ter part of 1940. One input well was drilled

to the Cypress sandstone on one lease and60,000 cu. ft. of gas from the Devonianlimestone is injected daily into the forma-

tion. Three input wells were drilled to the

Bethel sandstone on another lease and100,000 cu. ft. of gas is injected daily

SECONDA R Y RECOVER Y 25

into this formation. An increase in gas

volume and some increase in oil produc-tion was obtained in the wells on the

lease.

Water-flooding.—Water-flooding of the

McClosky limestone by the Pure Oil Co.on the B. Travis lease, sec. 33, T. 3 N.,

R. 8 E., Clay County, was discontinuedearly in 1940. Another project was started

in March 1940 on the T. H. Tetrick lease,

sec. 9, T. 2 N., R. 8 E., Clay County, bythe same company. The experiment wasconducted until October 1940, duringwhich time 225,000 bbl. of water was in-

jected into the McClosky limestone. Bothexperiments were discontinued because of

the inconclusive and conflicting evidenceregarding the effects upon production.

During 1940 there was little change in

repressuring or water-flooding operations

in the old southeastern Illinois field or in

the old fields ot western and southwesternIllinois.
