PLAINS CAPITAL
PLAINS CAPITAL is a Texas oil lease in Starr County, Railroad Commission district 04, operated by Mortimer Production Company. It has 2 wellbores on file with the Commission. Reported production runs from November 2021 to August 2026, totalling 122,146 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 $4.0M, with roughly $1.4M 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 2,188 barrels a month, about 1,094 per wellbore. Its strongest month on the record we hold was March 2024, at 3,386 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
