SAN AMBROSIA F (SA) 12
SAN AMBROSIA F (SA) 12 is a Texas gas lease in Webb County, Railroad Commission district 01, operated by SM Energy Company. It has 1 wellbore on file with the Commission. Reported production runs from November 2015 to August 2026, totalling 379,074 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 $4K, with roughly $631 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 21 thousand cubic feet a month. Its strongest month on the record we hold was August 2016, at 22,439 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.
