THORNY DEVIL
THORNY DEVIL is a Texas oil lease in Brazos County, Railroad Commission district 05, operated by Halcon Operating Co., Inc. It has 3 wellbores on file with the Commission. Reported production runs from October 2015 to August 2026, totalling 528,995 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 $3.1M, with roughly $849K 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 1,215 barrels a month, about 405 per wellbore. Its strongest month on the record we hold was April 2018, at 30,625 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.
