153 months across Nebraska carry two filings naming different operators, with nothing in the record marking either as the revision. Those months name no operator here rather than one chosen for them.

Monthly oil production

252 months filed with the Nebraska Oil and Gas Conservation Commission, Jan 2005 to Dec 2025. Volumes are bbl at lease level — a lease can cover many wells, so this is not a well's output.

Lease-level volumes as filed with the Nebraska Oil and Gas Conservation Commission. A blank well count is a month the state filed no count for, not a month with no wells.

Monthly water production

252 months filed with the Nebraska Oil and Gas Conservation Commission, Jan 2005 to Dec 2025. Volumes are bbl at lease level — a lease can cover many wells, so this is not a well's output.
