HEFLEY
HEFLEY is a Texas gas lease in Hemphill County, Railroad Commission district 10, operated by Granite Operating Company. It has 1 wellbore on file with the Commission. Reported production runs from May 2008 to August 2026, totalling 420,047 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 $70K, with roughly $14K 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 489 thousand cubic feet a month. Its strongest month on the record we hold was November 2020, at 9,540 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.
