SULLIVAN DEEP
SULLIVAN DEEP is a Texas gas lease in Brooks County, Railroad Commission district 04, operated by Maguire Oil Company. It has 1 wellbore on file with the Commission. Reported production runs from July 2001 to August 2026, totalling 1,210,543 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 $44K, with roughly $6K expected over the next twelve months.
