THUNDERBOLT C21-9 UNIT
THUNDERBOLT C21-9 UNIT is a Texas oil lease in Reeves County, Railroad Commission district 08, operated by Cimarex Energy Co. It has 1 wellbore on file with the Commission. Reported production runs from July 2015 to August 2026, totalling 552,761 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 $7.8M, with roughly $1.6M 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 1,870 barrels a month. Its strongest month on the record we hold was July 2016, at 12,225 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
