FOSTER, MARY
FOSTER, MARY is a Texas oil lease in Mitchell County, Railroad Commission district 08, operated by Crownquest Operating, LLC. It has 2 wellbores on file with the Commission. Reported production runs from November 2007 to August 2026, totalling 44,257 barrels. The lease is intermittent. 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 $17K, with roughly $3K 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 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was July 2017, at 374 barrels. In our own backtest, leases producing at this rate are forecast to within about 100% 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.
