SAN AMBROSIA D (SA15)

SAN AMBROSIA D (SA15) 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 May 2025 to August 2026, totalling 180,055 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 a standard royalty share at about $75K, with roughly $40K expected over the next twelve months. Over the last twelve months on file it averaged 15,005 thousand cubic feet a month. Its strongest month on the record we hold was July 2025, at 28,815 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 18% 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.

Production figures are as reported to the Railroad Commission of Texas. The value shown is an estimate produced by fitting a decline curve to that reported history; it is not an offer or an appraisal.
