The following jersons were appointed to the Study Committee by Governor Adlai E. Stevenson, early in 1952, o assist in the compilation of data on water flooding operations in Illinois oil pools during 1951: Paul A.

Wilson The Texas Company Salem, Illinois R. A. Wilson Tidewater Associated Oil Company Robinson, Illinois As a means to collect information on the water injection projects in operation during Figure 3 SUBSURFACE CONTOUR MAP OF THE ILLINOIS BASIN 1951, the Study Committee set up a questionnaire on July 1, 1952. The Geological Survey sent the questionnaire to all water flood operators in Illinois and compiled the data returned. This questionnaire did not request data on gas injection operations other than whether or not gas injection had previously been used. This report supplements two previous summaries of water flooding operations in Illinois which were published by the Interstate Oil Compact Commission, "Summary of Water Flooding Operations in Illinois, 1950," which reported operations during 1949, and "Summary of Water Flooding Operations in Illinois to 1951," which reported operations during 1950. These reports were reprinted by the Illinois State Geological Survey as Circulars 165 and 176 respectively. SUMMARY OF RESULTS Table I presents a summary of the information collected concerning water flood projects in operation during 1951. The data are arranged alphabetically by fields and include 84 water flood projects. Excluding the McClosky "dump" floods in the Clay City Consolidated field, there were approximately 90 water floods in operation in Illinois during 1951. Table I provides data on 93 percent of these projects. In terms of cumulative figures, however, this summary ap- proaches 100 percent coverage because the unreported projects are small pilot floods. A total of 57,146,845 barrels of water was injected during 1951, and 6,672,008 barrels of water flood oil was produced (exclusive of the McClosky "dump" floods), or a ratio of 8.5 barrels of water for each barrel of oil produced. A cumulative total of 148,279,296 barrels of water had been injected by the end of 1951 in recovering 21,889,880 barrels of oil, or an input water-oil ratio of 6.8. The cumulative input water -oil ratio is lower than the 1951 ratio because a considerable number of new projects were started in 1951 (and a few in 1950) from which ippreciable increases in oil production had not been realized by the end of the year. The 6,672,008 barrels of water flood oil recovered in 1951 is 11 percent of the state's otal oil production of 60,244,000 barrels. Comparable figures for 1950 were 3,107,154 barrels >f water flood oil out of a total of 62,028,000 barrels. It is interesting to note that the 17,643 iroductive acres that were subjected to injection during 1951 represent only 4 percent of the tate's total oil-productive area. This is an impressive indication of the contribution water looding is making to the recovery of one of the state's most valuable mineral resources. It is estimated that the McClosky "dump" floods recovered 1 and 1-2 million barrels f water flood oil during 1951 and have an accumulated secondary recovery of 8 million barrels. ,'hus, the total accumulated water flood oil recovery in Illinois was approximately 30 million arrels by the end of 1951. Table II presents data on the four pressure maintenance projects that used water in- action during 1951. The oil -production statistics include both primary recovery and any addi- onal oil obtained by pressure maintenance operations. These water injection operations augment atural water drives. Each project listed in Tables I and II has been numbered, and corresponding numbers i Figure 1 show the location of water flood and pressure maintenance operations in Illinois uring 1951. A generalized geologic column (Fig. 2) indicates the oil-producing formations in the l.inois Basin. Listed opposite these oil-producing formations are the number of reported water bods as taken from Table I. It will be seen that the water floods are divided almost equally Itween Penns ylvanian and Mississippian formations and that three limestone formations are -'ting flooded among a predominant number of sandstones. A subsurface contour map of the Illinois Basin is shown in Fig. 3, which is based on the :bsea elevation of the base of the Kinderhook-New Albany shale (see Fig. 2). This contour map i reproduced from "Developments in Eastern Interior Basin in 1940" by A. H. Bell (Bull. Jnerican Assoc. Petrol. Geol. , Vol. 25 No. 6, 1941, also Illinois Geol. Survey 111.

Foley* Increased water flooding operations in Illinois are accompanied by an increased demand for water. In many parts of the oil fields of southern Illinois, water, especially groundwater, is in limited supply. Brine is available at most places in the oil fields but not usually in quan- tities adequate for large-scale water flooding projects such as the Salem Unit or the Benton Unit. It is necessary, therefore, in most flooding projects to supplement available brine with fresh water from streams and wells. The availability of water from streams is usually readily determined, and data on stream flows can be obtained from the District Engineer, U. S. Geological Survey, 605 South Neil Street, Champaign, Illinois, and the Illinois State Water Survey, Urbana, Illinois. Groundwater, other than brines, in the oil fields of southern Illinois must be obtained largely from the surficial glacial drift deposits and recent valley alluvium or in some places from Pennsylvanian sandstones or Mississippian limestones. There are many good aquifers in the glacial drift and alluvial deposits, but careful search of well records and field study is necessary to locate them. Recent alluvial deposits are found in present stream valleys. The largest de- posits of water -yielding sand and gravel in the glacial drift are usually found in buried preglacial valleys or in valleys that drained from melting ice sheets. The first problem is the discovery and mapping of the buried valleys, after which the location of water -yielding sand or gravel in them requires additional detailed investigation. The Illinois State Geological Survey has located many buried valleys but many more years of study will be necessary before all potential water- yielding deposits are known (Horberg, Leland, Bedrock Topography of Illinois: Illinois Geol. Survey Bull. 73, 1950). Before beginning field exploration for groundwater sources, review of the data on file in the State Geological Survey and the State Water Survey is essential and frequently indicates favorable avenues for further investigation. These studies commonly point to the need for sur- face electrical earth resistivity exploration and a field canvass of existing water sources. The electrical earth resistivity method has been used with much success for more than 20 years by the Illinois Geological Survey to locate test drilling sites for probable deposits of sand and gravel in the unconsolidated glacial and fluvial overburden. This method is not infallible but is a very useful geophysical tool when combined with geological data by experienced personnel. After geophysical, geologic, and test drilling data are assembled and analyzed, deter- mination of the capacity and characteristics of the water -yielding formation by pumping test procedures is the final step before proceeding to construction of the water supply development. The Illinois Water Survey is prepared to furnish measuring equipment and skilled observational personnel for work of this type. The 130,000 well logs on file in the Illinois Geological Survey are an abundant source of data for work in groundwater geology. Unfortunately, logs of many oil wells give no informa- tion or only sketchy information on the unconsolidated material above bedrock. Thousands of logs merely report "surface material." It is urged that oil operators make a specific effort to obtain detailed logs of the surficial material, for that material might be an important source of groundwater. Complete logs will greatly improve the assistance which the Geological Survey will be able to give in locating groundwater. *Geologist and Head, Division of Groundwater Geology and Geophysical Exploration, Illinois State Geological Survey.
