ALDWELL M R40
ALDWELL M R40 is a Texas oil lease in Reagan County, Railroad Commission district 7C, operated by Pioneer Natural Res. USA, Inc. It has 8 wellbores on file with the Commission. Reported production runs from April 2017 to August 2026, totalling 2,425,080 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 $11.6M, with roughly $5.4M 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 12,558 barrels a month, about 1,570 per wellbore. Its strongest month on the record we hold was September 2017, at 145,756 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
