Katz (Strawn) Unit #22 (API 42-433-32296) is a plugged well in Stonewall County, plugged July 30, 2010, last operated by Atlas Operating LLC.

The RRC has issued one drilling permit (amended once), issued November 4, 1987, permitted to 5,200 ft.

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

Completion filings report one formation top, including Strawn.

Its 3 leases have reported 14.4M barrels of oil and 30.2M mcf of gas since January 1993, last reporting volume in March 2026. The leases carry 330 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
