MARQUETTE-WEST IRONOSA C
MARQUETTE-WEST IRONOSA C is a Texas gas lease in San Augustine 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 2024 to August 2026, totalling 5,072,112 thousand cubic feet. The lease is intermittent. 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 $70.7M, with roughly $10.7M 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 392,230 thousand cubic feet a month. Its strongest month on the record we hold was September 2025, at 560,118 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.
