STIFFLEMIRE
STIFFLEMIRE is a Texas oil lease in Burleson County, Railroad Commission district 05, operated by Halcon Operating Co., Inc. It has 4 wellbores on file with the Commission. Reported production runs from March 2014 to August 2026, totalling 643,038 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 $6.3M, with roughly $1.5M 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 1,964 barrels a month, about 491 per wellbore. Its strongest month on the record we hold was January 2019, at 29,132 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.
