AMACKER66
AMACKER66 is a Texas oil lease in Upton County, Railroad Commission district 7C, operated by Henry Petroleum LP. It has 7 wellbores on file with the Commission. Reported production runs from September 2004 to August 2026, totalling 433,538 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 $646K, with roughly $118K 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 163 barrels a month, about 23 per wellbore. Its strongest month on the record we hold was October 2016, at 1,347 barrels. In our own backtest, leases producing at this rate are forecast to within about 22% 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.
