WINDHAM TXL Q3
WINDHAM TXL Q3 is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Cog Operating LLC. It has 1 wellbore on file with the Commission. Reported production runs from May 2021 to August 2026, totalling 438,806 barrels. 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 $13.2M, with roughly $2.9M 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 4,816 barrels a month. Its strongest month on the record we hold was January 2022, at 34,085 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
