Stonewall County · Katz (Strawn) field  · Vertical

Katz (Strawn) Unit #26 (API 42-433-32570) is a plugged well in Stonewall County, plugged February 10, 2010, last operated by Atlas Operating LLC.

The RRC has issued one drilling permit (amended once), issued December 5, 1989, permitted to 5,300 ft.

It was permitted by Tex/Con Oil & Gas Company and has since transferred to Atlas Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Coleman Junction, Strawn, 2nd Sand, 3rd Sand.

Its 3 leases have reported 15.5M barrels of oil and 30.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 343 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.
