STATE TRACT M-99142

STATE TRACT M-99142 is a Texas gas lease in Zapata County, Railroad Commission district 04, operated by Coastal Oil & Gas Corporation. It has 1 wellbore on file with the Commission. Reported production runs from March 1999 to August 2026, totalling 706,246 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 $20K, with roughly $8K expected over the next twelve months. An individual royalty owner receives their own decimal interest times that figure. Over the last twelve months on file it averaged 464 thousand cubic feet a month. Its strongest month on the record we hold was May 2023, at 1,205 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 22% of what they went on to produce, and that measured error is the range shown on the page rather than a confidence of our own devising.
