WALLING & COSTLEY -B-
WALLING & COSTLEY -B- is a Texas oil lease in Ward County, Railroad Commission district 08, operated by Jag Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from May 1995 to August 2026, totalling 21,652 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 $4K, with roughly $754 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 4 barrels a month. Its strongest month on the record we hold was June 2016, at 97 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.
