COMBS UNIT
COMBS UNIT is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Murphy Expl. & Prod. Co. - USA. It has 4 wellbores on file with the Commission. Reported production runs from August 2012 to August 2026, totalling 796,538 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 $3.3M, with roughly $735K 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 1,052 barrels a month, about 263 per wellbore. Its strongest month on the record we hold was October 2016, at 3,526 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.
