Columbus Field Unit #604 (API 42-089-00036) is a permitted well in Colorado County filed by Oxy USA Inc.; no completion report is on file yet.
The RRC has issued one drilling permit, issued July 27, 1992, permitted to 10,500 ft.
It was permitted by Oxy USA Inc. and has since transferred to Cities Service Oil CO. on the wellbore schedule.
Completion filings report 4 formation tops, including Wilcox, Columbus (5-3), Columbus (6-Gg), Columbus (7-C).
Its 4 leases have reported 1.68M barrels of oil and 4.64M mcf of gas since January 1993, last reporting in July 2026. The leases carry 72 wells, so these are lease totals, not this well alone.
