DUANE 18T
DUANE 18T is a Texas oil lease in Glasscock County, Railroad Commission district 08, operated by Crownquest Operating, LLC. It has 2 wellbores on file with the Commission. Reported production runs from June 2013 to August 2026, totalling 33,083 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 $367K, with roughly $64K 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 70 barrels a month, about 35 per wellbore. Its strongest month on the record we hold was June 2024, at 363 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
