MCMASTER '244'
MCMASTER '244' is a Texas oil lease in Nolan County, Railroad Commission district 7B, operated by Cinnabar Operating, LLC. It has 1 wellbore on file with the Commission. Reported production runs from May 2015 to August 2026, totalling 15,162 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 $335K, with roughly $64K 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 82 barrels a month. Its strongest month on the record we hold was August 2021, at 191 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
