King County · Anne Tandy (Strawn) field · Shut In · Vertical
Big -S- (Twin Peaks) Unit #20 (API 42-269-31220) is a well in King County operated by High River Res Operating LLC, completed March 20, 1990 and listed as shut in on the RRC schedule, shut in February 1, 2014.
The RRC has issued 2 drilling permits (amended once) between 1984 and 1990, permitted to 6,000 ft.
It was permitted by Pacific Enterprises Oil CO.(USA) and has since transferred to High River Res Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Coleman Junction, Base Coleman Juntion, Base Dothan Lime, Saddle Creek.
Its 3 leases have reported 1.09M barrels of oil and 44.8K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 43 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Pacific Enterprises Oil Co.(usa); the EWA schedule now lists a different operator.
