Cox W. #5 (API 42-079-31396) is a well in Cochran County operated by Acoma Operating LLC, completed October 8, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued May 7, 1981, permitted to 5,000 ft.
It was permitted by Nielson Enterprises Inc. and has since transferred to Acoma Operating LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Rustler, Yates, San Andres, N/A.
Its lease has reported 27.6K barrels of oil and 10.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 11.5K barrels injected in the 12 months reported through February 2025.
