Sundown Unit #113 (API 42-219-37477) is a well in Hockley County operated by Hilcorp Energy Company, completed March 24, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued January 16, 2019, permitted to 6,000 ft.

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

Completion filings report 10 formation tops, including Santa Rosa, Yates, San Andres, Abo.

Its lease has reported 6.39M barrels of oil and 2.45M mcf of gas since January 1993, last reporting in July 2026. The lease carries 103 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit; TexNet located 0 M2+ earthquakes within 10 km over the last two years.

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