Ector County · Cowden North field · Injection · Vertical
Corrigan Cowden Unit #321 (API 42-135-34507) is a well in Ector County operated by Oxy USA Inc., completed April 1, 2022 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued March 16, 1984, permitted to 4,600 ft.
It was permitted by Arco Oil & Gas CO. and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
Its lease has reported 6.42M barrels of oil and 1.79M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 56 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 43.2K barrels injected in the 12 months reported through November 2025.
