GRAY-GRIFFIN UNIT
GRAY-GRIFFIN UNIT is a Texas gas lease in Hill County, Railroad Commission district 09, operated by Quicksilver Resources Inc. It has 1 wellbore on file with the Commission. Reported production runs from June 2008 to August 2026, totalling 1,197,150 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 $409K, with roughly $62K 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 2,681 thousand cubic feet a month. Its strongest month on the record we hold was February 2017, at 5,646 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.
