Illinois produced 63,708,000 bbl of crude oil in 1965, down 9.2% from 1964. Approximately 43,729,000 bbl, or 68.6% was from secondary recovery waterflood projects. Of the 2,101 drilling operations completed, 1,244 were new holes drilled as oil and gas tests. Of these, 573 were completed as oil wells and 11 shut-in as gas wells. In addition, 62 former dry holes were reworked and completed as oil wells, and 21 former producers were reworked and completed as oil wells in new pay zones. Of the new tests for oil and gas, 25% were wildcats. 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 bbl at the end of 1964 to 363.4 million bbl 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. There are 10 underground mined caverns for storage for liquefied petroleum gases. Controlled waterfloods reported at the end of 1965 totaled 933. There were 115 new projects reported during 1965, offset partially by 35 abandonments. Tabular data show complete details.
