NEFF WEST E 9-4
NEFF WEST E 9-4 is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by De IV Operating, LLC. It has 1 wellbore on file with the Commission. Reported production runs from November 2024 to August 2026, totalling 217,434 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 $8.9M, with roughly $3.3M 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 7,151 barrels a month. Its strongest month on the record we hold was January 2025, at 37,862 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.
