SHERMAN /8900 PENN./ UNIT
SHERMAN /8900 PENN./ UNIT is a Texas oil lease in Grayson County, Railroad Commission district 09, operated by Chevron U. S. A. Inc. It has 36 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 409,780 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 $1.7M, with roughly $275K 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 167 barrels a month, about 5 per wellbore. Its strongest month on the record we hold was October 2018, at 899 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.
