COSTELLO
COSTELLO is a Texas gas lease in Palo Pinto County, Railroad Commission district 7B, operated by J Oil & Gas Inc. It has 1 wellbore on file with the Commission. Reported production runs from February 1997 to August 2026, totalling 51,187 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 $4K, with roughly $470 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 24 thousand cubic feet a month. Its strongest month on the record we hold was October 2019, at 393 thousand cubic feet.
