Yoakum County · Prentice field · Injection · Vertical
Central Glorieta Unit #4CU (API 42-501-33114) is a well in Yoakum County operated by Occidental Permian Ltd., completed December 8, 1990 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1986 and 1992, permitted to 6,904 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 4 formation tops, including San Andres, Glorieta, Rustler, Clear Fork.
Its 2 leases have reported 14.7M barrels of oil and 3.19M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 253 wells, so these are lease totals, not this well alone.
It holds 2 active disposal or injection permits, with 341K barrels injected in the 12 months reported through November 2025.
