NUNN-GANZE 18D
NUNN-GANZE 18D is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Pioneer Natural Res. USA, Inc. It has 1 wellbore on file with the Commission. Reported production runs from July 2025 to August 2026, totalling 151,760 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 $82.5M, with roughly $18.3M 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 12,492 barrels a month. Its strongest month on the record we hold was January 2026, at 32,152 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.
