In Kansas, drilling activity in 1981 reached an all-time high of 6865 wells, a 30% increase over 1980. Exploration and new development drilling of oil reservoirs dominated this activity with oil completions up 42.4% to 3089, while completions of gas wells were up only 8% to 617 wells. Total footage drilled amounted to 23,618,361 compared with 14,546,356 in 1980. Approximately 22% of total wells were classified as exploratory, 77% were development, and less than 1% were miscellaneous tests. Exploratory drilling continued to spread slowly into the lesser drilled areas of the state while development drilling favored the well-established producing counties. The average depth of an exploratory test was 4063 ft or 79 ft deeper than last year, while development wells averaged 3260 ft in depth. All wells classified as exploratory had a success rate of 21%, compared to 64% for all development wells. The success rate of all wells drilled was 54%. In Missouri, drilling was up a moderate 13.5% over last year. However, the most startling information was the 200% increase in new-field wildcat completions, which were drilled in 6 counties. Total footage drilled was 133,531 compared with 77,525 in 1980. The average depth of a test was 339 ft. Oil production for the year was 226,206 bbl, up 70%. The success rate among all tests drilled was 42.13%.
