BIG TWELVE
BIG TWELVE is a Texas gas lease in Jackson County, Railroad Commission district 02, operated by Allegro Investments, Inc. It has 1 wellbore on file with the Commission. Reported production runs from February 2003 to August 2026, totalling 690,469 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 $372K, with roughly $78K 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 665 thousand cubic feet a month. Its strongest month on the record we hold was September 2017, at 2,205 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.
