Illinois produced 26,066,652 bbl of crude oil in 1975, a decline of 5.4% from 1974. The estimated average price per barrel was $10.48; the estimated value for the oil produced in Illinois in 1975 was $273,000,000. A total of 911 new holes was drilled to test for oil and gas, an increase of 19.4% from 1974. These tests resulted in 433 oil wells, 4 gas wells, and 474 dry holes. In addition, 41 former dry holes were reworked or deepened and recompleted as producers (40 oil, one gas), and 13 former producers were reentered and recompleted as oil wells in new pay zones. Of the 911 new tests, 216, or 23.7%, were wildcats (half a mile or more from production), of which 18 were completed as producers, a success ratio of 8.3%. A total of 179 service wells (water input, salt-water disposal, etc.) was completed in 1975, an increase of 28.8% from 1974. Twenty-seven new waterfloods were added, and 12 waterfloods were abandoned during 1975. Waterfloods accounted for 17,579,900 bbl, of 67.4%, of the state total.
