HALFMANN, DELBERT
HALFMANN, DELBERT is a Texas gas lease in Glasscock County, Railroad Commission district 08, operated by Exxon Corp. It has 1 wellbore on file with the Commission. Reported production runs from December 1993 to August 2026, totalling 633,140 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 $71K, with roughly $12K 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 407 thousand cubic feet a month. Its strongest month on the record we hold was June 2016, at 1,802 thousand cubic feet. 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.
