DONNELL 'B'
DONNELL 'B' is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Comstock Oil & Gas, LP. It has 3 wellbores on file with the Commission. Reported production runs from April 2012 to August 2026, totalling 518,667 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 $2.4M, with roughly $539K 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 742 barrels a month, about 247 per wellbore. Its strongest month on the record we hold was May 2016, at 4,313 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.
