Central Ownby Unit #8 (API 42-501-02574) is a well in Yoakum County operated by Occidental Permian Ltd., completed January 28, 2017 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 21, 1977, permitted to 6,937 ft.
It was permitted by Shell Oil Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 5 formation tops, including Santa Rosa, Yates, San Andres, Glorieta.
Its lease has reported 12.3M barrels of oil and 2.69M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 156 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 17.1K barrels injected in the 12 months reported through November 2025.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
