WHITLEY-DUBOSE UNIT
WHITLEY-DUBOSE UNIT is a Texas oil lease in Frio County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from February 2014 to August 2026, totalling 106,176 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 $292K, with roughly $175K 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 638 barrels a month. Its strongest month on the record we hold was August 2025, at 2,871 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.
