MANGIONE 01
MANGIONE 01 is a Texas gas lease in Karnes County, Railroad Commission district 02, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from May 2023 to August 2026, totalling 970,598 thousand cubic feet. 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 $1.2M, with roughly $764K 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 6,632 thousand cubic feet a month. Its strongest month on the record we hold was June 2023, at 139,408 thousand cubic feet. In our own backtest, leases producing at this rate are forecast to within about 17% 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.
