SON 136
SON 136 is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Crownquest Operating, LLC. It has 2 wellbores on file with the Commission. Reported production runs from October 2017 to August 2026, totalling 70,129 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 $692K, with roughly $207K 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 324 barrels a month, about 162 per wellbore. Its strongest month on the record we hold was March 2018, at 2,815 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.
