74 RANCH UNIT S1
74 RANCH UNIT S1 is a Texas oil lease in Atascosa County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 5 wellbores on file with the Commission. Reported production runs from April 2021 to August 2026, totalling 1,293,386 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 $15.4M, with roughly $4.6M 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 7,049 barrels a month, about 1,410 per wellbore. Its strongest month on the record we hold was August 2021, at 193,514 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.
