PETROLEUM INDUSTRY IN ILLINOIS, 1965 JACOB VAN DEN BERG, T. F. LAWRY AND RICHARD F. MAST ABSTRACT Illinois produced 63,708,000 barrels of crude oil in 1965, down 9 . 2 percent from 1964. Approximately 43, 729, 000 barrels, or 68 .6 percent, of this production was from secondary recovery waterflood projects. Until near the end of the year, the price of Illinois crude oil at the wells was based on a gravity scale that ranged from $2.42 a barrel for oil with an API gravity of 20 degrees to $3.00 a barrel for oil with an API gravity of 40-45 degrees. In December the price was increased 10 cents a barrel for all gravities. Total estimated value of crude oil produced in Illinois in 1965 was $186,665,000. Of the 2, 101 drilling operations completed by the oil and gas industry, 1,244 were new holes drilled as oil and gas tests. Of these, 573 were completed as oil wells and 11 as shut-in gas wells. In addition, 62 former dry holes were re- worked and completed as oil wells, and 21 former producers were reworked and com- pleted as oil wells in new pay zones. Of the 1,244 new tests for oil and gas, 315, or 25 percent, were wildcats. There were 131 new service wells drilled and 417 old wells, mostly producers, were converted to service wells . Forty-two oil and gas structure tests were drilled. There were 184 well completions reported in connection with underground storage of natural gas. Nine new oil pools, 17 pool extensions, and 2 new pay zones in pools were discovered in 1965. Estimated crude oil reserves declined from 404.7 million barrels at the end of 1964 to 363.4 million barrels at the end of 1965. There are 21 underground natural gas storage projects in operation or being developed in Illinois for gas from other states. Estimated ultimate capacity is 740 billion cubic feet. There are 10 underground mined caverns for storage of liquefied petroleum gases with a total capacity of 2,786, 500 barrels. Controlled waterfloods reported at the end of 1965 totalled 933. There were 115 new projects reported during 1965, offset partially by 35 abandonments. Of the 45,006,000 barrels of oil produced from secondary recovery during 1965, controlled waterflood projects reported 43,729,000 barrels. Five pressure maintenance projects produced 777,000 barrels, and dump floods produced 500,000 barrels of crude oil. At the end of 1965, cumulative oil produced by fluid injection, including that by dump floods and pressure maintenance projects, was 531, 102,000 barrels At the end of 1965, 340, 097 acres were under fluid injection. This includes 32,721 acres brought under fluid injection by the 115 new projects. 2 . PART I.
