Katz (Strawn) Unit #15 (API 42-433-32387) is a plugged well in Stonewall County, plugged September 20, 2010, last operated by Atlas Operating LLC.

The RRC has issued one drilling permit, issued April 28, 1988, permitted to 5,250 ft.

It was permitted by Phillips Petroleum Company and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Wichita-Albany, Wolfcamp, Coleman Junction, Home Creek Lm.

Its 3 leases have reported 15.3M barrels of oil and 30.4M mcf of gas since January 1993, last reporting volume in March 2026. The leases carry 319 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.
