Lease 1001108529 · Butler County, Kansas · SW Sec 9 T26S R3E · DOR 101611
Monthly oil production
314 months filed with the Kansas Geological Survey, Jan 1980 to Feb 2026. 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 185,267.69 bbl.
