SCHROEDER-CHAPMAN UNIT
SCHROEDER-CHAPMAN UNIT 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 July 2011 to August 2026, totalling 798,097 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 $3.4M, with roughly $1.1M 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 1,778 barrels a month, about 356 per wellbore. Its strongest month on the record we hold was July 2022, at 47,272 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.
