WINDHAM, R. S.
WINDHAM, R. S. is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Southwest Royalties, Inc. It has 1 wellbore on file with the Commission. Reported production runs from October 2002 to August 2026, totalling 13,359 barrels. 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 $196K, with roughly $27K 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 barrels a month. Its strongest month on the record we hold was November 2022, at 80 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
