MARIA
MARIA is a Texas oil lease in Gaines County, Railroad Commission district 08, operated by Sloan Petroleum Inc. It has 3 wellbores on file with the Commission. Reported production runs from September 1999 to August 2026, totalling 267,608 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 $806K, with roughly $183K 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 316 barrels a month, about 105 per wellbore. Its strongest month on the record we hold was March 2019, at 6,805 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
