MUMME RANCH

MUMME RANCH is a Texas gas lease in La Salle County, Railroad Commission district 01, operated by Carrizo Oil & Gas, Inc. It has 1 wellbore on file with the Commission. Reported production runs from October 2010 to August 2026, totalling 554,131 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 $210K, with roughly $40K 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 82 thousand cubic feet a month. Its strongest month on the record we hold was April 2019, at 8,122 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
