Reported production runs from January 1993 to August 2026, totalling 209,257 thousand cubic feet. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values the whole lease — a 100% undivided interest — at about $28K, with roughly $4K expected over the next twelve months.
