MAYFIELD 40
MAYFIELD 40 is a Texas gas lease in Sutton County, Railroad Commission district 7C, operated by Dominion Oklahoma Texas E&P, Inc. It has 1 wellbore on file with the Commission. Reported production runs from June 2006 to August 2026, totalling 116,956 thousand cubic feet. 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 $8K, with roughly $953 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 53 thousand cubic feet a month. Its strongest month on the record we hold was September 2019, at 136 thousand cubic feet. 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.
