FENWICK 10-3 C
FENWICK 10-3 C is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 4 wellbores on file with the Commission. Reported production runs from February 2025 to August 2026, totalling 364,580 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 $45.2M, with roughly $9.8M 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 28,672 barrels a month, about 7,168 per wellbore. Its strongest month on the record we hold was October 2025, at 59,752 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.
