West Sundown Unit #7 (API 42-219-01902) is a horizontal well in Hockley County operated by Hilcorp Energy Company, completed August 20, 2025 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued December 1, 2003, permitted to 5,002 ft.

It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 3 formation tops, including Rustler, Tansill, Yates.

Its 2 leases have reported 7.45M barrels of oil and 5.02M mcf of gas since January 1993, last reporting in July 2026. The leases carry 252 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.
