FOSTER UNIT
FOSTER UNIT 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 January 2015 to August 2026, totalling 746,714 thousand cubic feet. The lease is shut in. 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 $558, with roughly $99 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 64 thousand cubic feet a month. Its strongest month on the record we hold was August 2019, at 20,444 thousand cubic feet.
