Hockley County · Slaughter field · Injection · Vertical
Slaughter Estate Unit #485 (API 42-219-35042) is a well in Hockley County operated by Hilcorp Energy Company, completed July 6, 2017 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits between 1987 and 1998, permitted to 8,400 ft.
It was permitted by Altura Energy Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 7 formation tops, including Rustler, San Andres, Glorieta, Tubb.
Its 3 leases have reported 51.7M barrels of oil and 202M mcf of gas since January 1993, last reporting in July 2026. The leases carry 440 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 1.28K barrels injected in the 12 months reported through December 2025.
