Monthly oil production
35 months filed with the Kansas Geological Survey, Jan 1980 to Sep 2000. Volumes are bbl at lease level — a lease can cover many wells, so this is not a well's output.
This lease was producing before 1980, and the series begins in January 1980. The total above covers the months shown, not the life of the lease; the state's own cumulative is 23,965.55 bbl.
