ASSAULT 125-127 B

ASSAULT 125-127 B is a Texas oil lease in Ward County, Railroad Commission district 08, operated by Manti Tarka Permian Op, LLC. It has 1 wellbore on file with the Commission. Reported production runs from August 2025 to August 2026, totalling 188,021 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 $17.9M, with roughly $7.3M 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 19,565 barrels a month. Its strongest month on the record we hold was September 2025, at 32,372 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.
