ISAAC
ISAAC is a Texas gas lease in Nacogdoches County, Railroad Commission district 06, operated by Southwestern Energy Prod. Co. It has 1 wellbore on file with the Commission. Reported production runs from July 2005 to August 2026, totalling 1,943,477 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 $135K, with roughly $22K 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 1,319 thousand cubic feet a month. Its strongest month on the record we hold was March 2021, at 6,544 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
