HIERHOLZER-HENKE UNIT
HIERHOLZER-HENKE UNIT is a Texas gas lease in Atascosa County, Railroad Commission district 01, operated by Marathon Oil Ef LLC. It has 1 wellbore on file with the Commission. Reported production runs from May 2012 to August 2026, totalling 194,460 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 $265K, with roughly $50K 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 126 thousand cubic feet a month. Its strongest month on the record we hold was July 2016, at 1,925 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.
