Enhanced Oil-Recovery Operations in Kansas, 1975

Data for 1,400 enhanced recovery projects in 69 Kansas counties are listed in this report, and a map shows the locations of these counties. Stratigraphic distribution of oil-producing zones and sub-surface water sources are also shown on a rock classification chart. Types of projects are indicated; these include 1 fireflood and 113 pressure-maintenance projects, 294 dump floods, 660 waterflood operations, and 332 that are not identified. During 1975, 73 repressuring applications were approved. Crude oil production in Kansas totaled 59,106,104 barrels during 1975; of this, 18,701,313 barrels were recovered from the projects but only 12,108,726 barrels (20.5%) were listed as production resulting directly from the fluid that was injected. County and project summaries shown include acreage figures, number of oil producing and input wells, and the amount of water injected and oil produced on the projects. Some recently abandoned projects are also listed. Research directed at developing new techniques for recovery of oil from large areas in Kansas where wells do not respond to present recovery techniques continues at Lawrence. Work also is progressing on schedule at the Cities Service Oil Company-Energy Research and Development Administration tertiary recovery pilot project in the old El Dorado field in Butler County. 3more » figures, 3 tables.« less
