DUNCAN

DUNCAN is a Texas oil lease in Matagorda County, Railroad Commission district 03, operated by Millennium Exploration Co. LLC. It has 1 wellbore on file with the Commission. Reported production runs from October 2016 to August 2026, totalling 58,398 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 $467K, with roughly $153K 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 292 barrels a month. Its strongest month on the record we hold was September 2017, at 2,503 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
