COPPENGER
COPPENGER is a Texas gas lease in Johnson County, Railroad Commission district 09, operated by Eog Resources, Inc. It has 1 wellbore on file with the Commission. Reported production runs from January 2007 to August 2026, totalling 621,060 thousand cubic feet. The lease is intermittent. 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 $1K, with roughly $834 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 198 thousand cubic feet a month. Its strongest month on the record we hold was January 2026, at 1,932 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.
