MENCHACA
MENCHACA is a Texas oil lease in Bexar County, Railroad Commission district 01, operated by Calk, Roger D. It has 2 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 3,426 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 $65K, with roughly $13K 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 12 barrels a month, about 6 per wellbore. Its strongest month on the record we hold was December 2016, at 20 barrels. 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.
