UL MASON EAST UNIT
UL MASON EAST UNIT is a Texas oil lease in Andrews County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 4 wellbores on file with the Commission. Reported production runs from March 2017 to August 2026, totalling 2,153,487 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 $20.7M, with roughly $5.2M 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 6,390 barrels a month, about 1,598 per wellbore. Its strongest month on the record we hold was May 2017, at 98,728 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
