SAN MIGUEL RANCH OL
SAN MIGUEL RANCH OL is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Swift Energy Operating, LLC. It has 11 wellbores on file with the Commission. Reported production runs from October 2010 to August 2026, totalling 608,123 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 $2.2M, with roughly $458K 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 585 barrels a month, about 53 per wellbore. Its strongest month on the record we hold was May 2016, at 2,491 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.
