HASEL26
HASEL26 is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Cog Operating LLC. It has 2 wellbores on file with the Commission. Reported production runs from October 2012 to August 2026, totalling 65,477 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 $87K, with roughly $16K 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 12 barrels a month, about 6 per wellbore. Its strongest month on the record we hold was November 2017, at 401 barrels. In our own backtest, leases producing at this rate are forecast to within about 45% 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.
