MANN5
MANN5 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 August 2007 to August 2026, totalling 79,264 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 $311K, with roughly $56K 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 108 barrels a month, about 54 per wellbore. Its strongest month on the record we hold was September 2017, at 582 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.
