HALFF36
HALFF36 is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Henry Petroleum LP. It has 2 wellbores on file with the Commission. Reported production runs from July 2005 to August 2026, totalling 60,704 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 $597K, with roughly $107K 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 91 barrels a month, about 45 per wellbore. Its strongest month on the record we hold was April 2021, at 507 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.
