WESLEY SWAIM UNIT
WESLEY SWAIM UNIT is a Texas oil lease in Mcmullen County, Railroad Commission district 01, operated by Talisman Energy USA Inc. It has 2 wellbores on file with the Commission. Reported production runs from August 2013 to August 2026, totalling 416,740 barrels. 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 $1.0M, with roughly $607K 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 344 barrels a month, about 172 per wellbore. Its strongest month on the record we hold was June 2016, at 3,437 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.
