WILHELM-SMITH UNIT A

WILHELM-SMITH UNIT A is a Texas oil lease in Atascosa County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 4 wellbores on file with the Commission. Reported production runs from August 2012 to August 2026, totalling 853,217 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 $762K, with roughly $144K 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 219 barrels a month, about 55 per wellbore. Its strongest month on the record we hold was May 2018, at 7,782 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.
