COUNTY LINE 12
COUNTY LINE 12 is a Texas gas lease in Stephens County, Railroad Commission district 7B, operated by Winn Exploration Co., Inc. It has 1 wellbore on file with the Commission. Reported production runs from October 1999 to August 2026, totalling 226,014 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 $82K, with roughly $13K 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 530 thousand cubic feet a month. Its strongest month on the record we hold was August 2025, at 916 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.
