O'BRIEN - 21
O'BRIEN - 21 is a Texas oil lease in Dawson County, Railroad Commission district 08, operated by Eastland Oil Company, The. It has 1 wellbore on file with the Commission. Reported production runs from November 2010 to August 2026, totalling 39,714 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 $361K, with roughly $69K 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 83 barrels a month. Its strongest month on the record we hold was August 2022, at 199 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.
