WINDHAM TXL R18
WINDHAM TXL R18 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 March 2020 to August 2026, totalling 430,664 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 $6.2M, with roughly $1.3M 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 1,891 barrels a month. Its strongest month on the record we hold was May 2020, at 26,976 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.
