Hockley County · Slaughter field · Injection · Vertical
Sundown Slaughter Unit #10A (API 42-219-35278) is a well in Hockley County operated by Bce-Mach Iii LLC, completed October 7, 1995 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued March 28, 1988, permitted to 5,200 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Its 2 leases have reported 51.2M barrels of oil and 30.9M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 713 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 135K barrels injected in the 12 months reported through December 2025.
