Stonewall County · Katz (Strawn) field · Injection · Directional
Katz (Strawn) Unit #105 (API 42-433-33510) is a disposal or injection well in Stonewall County operated by Atlas Operating LLC under an active UIC permit.
The RRC has issued one drilling permit (amended once), issued October 19, 2009, permitted to 5,375 ft.
It was permitted by Kinder Morgan Production CO LLC and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Coleman Junction, Palo Pinto, Katz Sand 1st, Katz Sand 2nd.
Its 2 leases have reported 13.1M barrels of oil and 30.2M mcf of gas since November 2009, last reporting volume in March 2026. The leases carry 286 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
