MUMME-LA SALLE UNIT
MUMME-LA SALLE UNIT is a Texas oil lease in La Salle County, Railroad Commission district 01, operated by Carrizo (Eagle Ford) LLC. It has 2 wellbores on file with the Commission. Reported production runs from July 2013 to August 2026, totalling 261,194 barrels. 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 $961K, with roughly $324K 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 484 barrels a month, about 242 per wellbore. Its strongest month on the record we hold was October 2019, at 18,228 barrels. 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.
