DONLEY
DONLEY is a Texas oil lease in Tom Green County, Railroad Commission district 7C, operated by Elco Oil & Gas. It has 2 wellbores on file with the Commission. Reported production runs from November 2011 to August 2026, totalling 3,231 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 $5K, with roughly $879 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 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was June 2016, at 84 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
