CAMPBELL EF

CAMPBELL EF is a Texas oil lease in Lee County, Railroad Commission district 03, operated by Sage Natural Resources LLC. It has 2 wellbores on file with the Commission. Reported production runs from September 2025 to August 2026, totalling 319,858 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 $41.9M, with roughly $19.7M 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 36,832 barrels a month, about 18,416 per wellbore. Its strongest month on the record we hold was October 2025, at 61,836 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.
