Data for 1448 enhanced oil-recovery projects are listed in this report, and a map shows their geographic distribution in 69 Kansas counties. Included are 698 projects identified as waterfloods, 397 pressure maintenance operations, 275 dump floods, 1 fireflood (thermal), 1 steam, and 1 air injection tat maybe converted to tertiary recovery, and 74 that were not identified. Total crude oil ... [Show full abstract] production in Kansas during 1977 was 57,496,021 barrels. Of this, 18,149,221 barrels (32%) were recovered from project areas. The records show that about 17 barels of water were injected from every barrel of oil produced. There were 5036 water injection wells and 11,450 oil wells in operation during the year in the project areas. A graph shows oil and natural gas production from the late 1800's to 1976, and given the years of oiland gas discoveries in Kansas structural provinces. Also shown is the approximate quality of oil produced by enhanced recovery methods each year. Table 1 of the report lists fields, pay zones and their, depths, and sources of water. Injection patterns are indicated and companies also furnished information on daily and yearly water injection. Annual and cumulative oil production figures are given. Stratigraphic positions of oil-producing zones and subsurface water sources are shown on a rock-classification chart. Tertiary oil-recovery research continues at the University of Kansas, which is aided by advice received from people working in the industry.
