Lease 1001118223 · Ellis County, Kansas · NWNESE Sec 30 T11S R19W · DOR 108531
Monthly oil production
369 months filed with the Kansas Geological Survey, Jan 1980 to Feb 2018. 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 316,625.47 bbl.
