MOSASAURUS UNIT
MOSASAURUS UNIT is a Texas gas lease in Angelina County, Railroad Commission district 06, operated by Aethon Energy Operating LLC. It has 1 wellbore on file with the Commission. Reported production runs from September 2025 to August 2026, totalling 3,057,001 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 $51.5M, with roughly $7.8M 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 382,125 thousand cubic feet a month. Its strongest month on the record we hold was December 2025, at 708,214 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
