Lease 1001109008 · Cowley County, Kansas · CSWNW Sec 10 T35S R4E · DOR 102086
Monthly oil production
190 months filed with the Kansas Geological Survey, Jan 1980 to Nov 2025. 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 44,449.60 bbl.
