MCCOY UNIT B
MCCOY UNIT B is a Texas oil lease in Live Oak County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 3 wellbores on file with the Commission. Reported production runs from October 2014 to August 2026, totalling 355,016 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 $731K, with roughly $361K 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 702 barrels a month, about 234 per wellbore. Its strongest month on the record we hold was May 2016, at 4,952 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.
