ROSS 48-1 B

ROSS 48-1 B is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 2 wellbores on file with the Commission. Reported production runs from June 2025 to August 2026, totalling 260,035 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 $98.2M, with roughly $22.0M 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 21,283 barrels a month, about 10,642 per wellbore. Its strongest month on the record we hold was January 2026, at 52,561 barrels. In our own backtest, leases producing at this rate are forecast to within about 18% 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.
