FOSTER MCDONALD
FOSTER MCDONALD is a Texas oil lease in Sterling County, Railroad Commission district 08, operated by Williams, Clayton Energy, Inc. It has 4 wellbores on file with the Commission. Reported production runs from September 2011 to August 2026, totalling 107,828 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 $479K, with roughly $71K 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 40 barrels a month, about 10 per wellbore. Its strongest month on the record we hold was October 2016, at 319 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
