Sundown Slaughter Unit #1331 (API 42-219-33223) is a well in Hockley County operated by Bce-Mach Iii LLC, completed June 21, 2006.

The RRC has issued 2 drilling permits between 1981 and 2010, permitted to 5,800 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 one formation top, including 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.

It holds an active disposal or injection permit.

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