King County · Katz (Strawn) field  · Directional

Katz (Strawn) Unit #2 (API 42-269-31666) is a plugged well in King County, plugged October 24, 2019, last operated by Atlas Operating LLC.

The RRC has issued 2 drilling permits between 1985 and 1988, permitted to 5,290 ft.

It was permitted by Standard Oil Production Company and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Valera, Coleman Junction, Palo Pinto, Cisco.

Its 4 leases have reported 14.6M barrels of oil and 30.2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 349 wells, so these are lease totals, not this well alone.
