Stonewall County · Katz (Strawn) field · Vertical
Katz (Strawn) Unit #3 (API 42-433-00837) is a plugged well in Stonewall County, plugged August 18, 2010, last operated by Atlas Operating LLC.
The RRC has issued one drilling permit, issued February 2, 1990, permitted to 5,200 ft.
It was permitted by BP Exploration Inc. and has since transferred to Atlas Operating LLC on the wellbore schedule.
Its 5 leases have reported 16.3M barrels of oil and 30.6M mcf of gas since January 1993, last reporting in July 2026. The leases carry 363 wells, so these are lease totals, not this well alone.
