UL 20 SPINNER B
UL 20 SPINNER B is a Texas oil lease in Winkler County, Railroad Commission district 08, operated by Pdeh LLC. It has 1 wellbore on file with the Commission. Reported production runs from November 2025 to August 2026, totalling 104,279 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 $50.8M, with roughly $11.3M 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 15,356 barrels a month. Its strongest month on the record we hold was December 2025, at 23,151 barrels. 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.
