GROSS-ROBERT PSA

GROSS-ROBERT PSA is a Texas oil lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from September 2019 to August 2026, totalling 358,195 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 $6.0M, with roughly $1.2M 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 1,587 barrels a month. Its strongest month on the record we hold was January 2020, at 40,700 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.
