RIO NUECES 37-44 UNIT 1
RIO NUECES 37-44 UNIT 1 is a Texas oil lease in Midland County, Railroad Commission district 08, operated by Endeavor Energy Resources L.P. It has 7 wellbores on file with the Commission. Reported production runs from February 2018 to August 2026, totalling 2,677,752 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 $23.4M, with roughly $7.9M 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 9,872 barrels a month, about 1,410 per wellbore. Its strongest month on the record we hold was March 2018, at 100,390 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.
