WINSTON 31-43 C
WINSTON 31-43 C is a Texas oil lease in Martin County, Railroad Commission district 08, operated by Diamondback E&P LLC. It has 2 wellbores on file with the Commission. Reported production runs from October 2022 to August 2026, totalling 507,927 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 $12.0M, with roughly $3.1M 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 5,298 barrels a month, about 2,649 per wellbore. Its strongest month on the record we hold was September 2023, at 46,036 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.
