WITHERSPOON
WITHERSPOON is a Texas oil lease in Atascosa County, Railroad Commission district 01, operated by Calk, J. M. Operating Co. It has 3 wellbores on file with the Commission. Reported production runs from January 1993 to August 2026, totalling 5,790 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 $20K, with roughly $4K 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 5 barrels a month, about 2 per wellbore. Its strongest month on the record we hold was June 2017, at 25 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.
