Lease 1001120890 · Decatur County, Kansas · CSWNE Sec 21 T5S R30W · DOR 110826
Monthly oil production
99 months filed with the Kansas Geological Survey, Jan 1980 to Jul 1990. 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 57,690 bbl.
