Sundown Slaughter Unit #1187AH (API 42-219-34407) is a horizontal well in Hockley County operated by Bce-Mach Iii LLC, completed September 26, 2000 and listed as producing on the RRC schedule.

The RRC has issued 4 drilling permits between 1984 and 2008, permitted to 5,486 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Rustler, Yates, San Andres.

Its 2 leases have reported 52M barrels of oil and 31.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 1,126 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
