FRANK SHALLER

FRANK SHALLER is a Texas gas lease in Hemphill County, Railroad Commission district 10, operated by Mewbourne Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from December 2010 to August 2026, totalling 1,385,794 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 $603K, with roughly $104K 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 2,763 thousand cubic feet a month. Its strongest month on the record we hold was July 2016, at 6,122 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.
