Hockley County · Slaughter field · Injection · Vertical
West Rkm Unit #325 (API 42-219-37454) is a well in Hockley County operated by Occidental Permian Eor LLC, completed November 5, 2021 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued September 21, 2018, permitted to 5,500 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Santa Rosa, Yates, San Andres, Abo.
Its lease has reported 23M barrels of oil and 10.9M mcf of gas since January 1993, last reporting in July 2026. The lease carries 304 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 33.7K barrels injected in the 12 months reported through December 2025; TexNet located 0 M2+ earthquakes within 10 km over the last two years.
