HALFF ESTATE "26"
HALFF ESTATE "26" is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by JM Cox Resources, L.P. It has 2 wellbores on file with the Commission. Reported production runs from April 2007 to August 2026, totalling 24,247 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 $5K, with roughly $789 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 barrels a month, about 1 per wellbore. Its strongest month on the record we hold was July 2019, at 130 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.
