JOHN ISAACS ET AL 'G'
JOHN ISAACS ET AL 'G' is a Texas gas lease in Hemphill County, Railroad Commission district 10, operated by Mewbourne Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from May 2012 to August 2026, totalling 877,518 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 $53K, with roughly $9K 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 106 thousand cubic feet a month. Its strongest month on the record we hold was August 2017, at 4,073 thousand cubic feet. 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.
