West Sundown Unit #1 (API 42-219-01686) is a horizontal well in Hockley County operated by Hilcorp Energy Company, completed December 6, 2024 and listed as shut in on the RRC schedule, shut in December 1, 2024.

The RRC has issued one drilling permit, issued November 21, 2000, permitted to 5,182 ft.

It was permitted by Bass Enterprises Production CO. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 5 formation tops, including Brown Lime, Big Lime/Perm, San Andres, 1st Dense.

Its 2 leases have reported 8.33M barrels of oil and 5.13M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 266 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.
