SIMPSON-MANN "C"
SIMPSON-MANN "C" is a Texas oil lease in Tom Green County, Railroad Commission district 7C, operated by Lawrence, C. F. & Assoc. Inc. It has 1 wellbore on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 812 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 $8K, with roughly $2K 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 3 barrels a month. Its strongest month on the record we hold was January 2024, at 5 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
