West RKM Unit #505
Hockley County · Slaughter field · Vertical
West Rkm Unit #505 (API 42-219-37457) is a well in Hockley County operated by Occidental Permian Eor LLC, completed March 23, 2019.
The RRC has issued one drilling permit (amended 3 times), issued September 21, 2018, permitted to 12,650 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, Wolfcamp.
Its 2 leases have reported 23M barrels of oil and 10.9M mcf of gas since January 1993, last reporting in July 2026. The leases carry 305 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 785K barrels injected in the 12 months reported through December 2025; TexNet located 0 M2+ earthquakes within 10 km over the last two years.
