MASTEN UNIT
MASTEN UNIT is a Texas oil lease in Cochran County, Railroad Commission district 8A, operated by Union Oil Company Of California. It has 63 wellbores on file with the Commission. Reported production runs from July 1994 to August 2026, totalling 968,195 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 $2.5M, with roughly $706K 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 1,111 barrels a month, about 18 per wellbore. Its strongest month on the record we hold was April 2017, at 3,243 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.
