Katz (Strawn) Unit #C 20 (API 42-433-33160) is a plugged well in Stonewall County, plugged January 13, 2010, last operated by Atlas Operating LLC.
The RRC has issued one drilling permit (amended once), issued November 23, 1998, permitted to 6,100 ft.
It was permitted by Merit Energy Company and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Des Monies, Strawn, Caddo, Bend.
Its 3 leases have reported 15.3M barrels of oil and 30.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 319 wells, so these are lease totals, not this well alone.
