MANN
MANN is a Texas gas lease in Harrison County, Railroad Commission district 06, operated by Howell & Sandlin, Inc. It has 1 wellbore on file with the Commission. Reported production runs from February 2000 to August 2026, totalling 676,652 thousand cubic feet. The lease is intermittent. 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 $3K, with roughly $343 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 14 thousand cubic feet a month. Its strongest month on the record we hold was September 2016, at 1,343 thousand cubic feet. 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.
