SUBLETT, J. GU
SUBLETT, J. GU is a Texas gas lease in San Augustine County, Railroad Commission district 06, operated by Devon Energy Production Co, L.P. It has 1 wellbore on file with the Commission. Reported production runs from July 2010 to August 2026, totalling 1,544,549 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 $138K, with roughly $25K 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 1,249 thousand cubic feet a month. Its strongest month on the record we hold was December 2023, at 20,244 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.
