ZAPP
ZAPP is a Texas gas lease in La Salle County, Railroad Commission district 01, operated by Talisman Energy USA Inc. It has 1 wellbore on file with the Commission. Reported production runs from June 2012 to August 2026, totalling 419,987 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 $188K, with roughly $89K 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 260 thousand cubic feet a month. Its strongest month on the record we hold was May 2016, at 4,508 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.
