Hockley County · Slaughter field · Shut In · Horizontal · Directional · Sidetrack
Sundown Slaughter Unit #348 (API 42-219-35614) is a horizontal well in Hockley County operated by Bce-Mach Iii LLC, completed February 19, 1994 and listed as shut in on the RRC schedule, shut in March 1, 2026.
The RRC has issued 2 drilling permits between 1990 and 1993, permitted to 5,853 ft.
It was permitted by Texaco E & P Inc. and has since transferred to Bce-Mach Iii LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Rustler, 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.
