South Welch Unit #514W (API 42-115-32093) is a well in Dawson County operated by Hilcorp Energy Company, completed August 13, 2011 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued August 22, 1984, permitted to 4,965 ft.

It was permitted by Cities Service Oil & Gas Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 3 formation tops, including Grayburg, Lovington, San Andres.

Its lease has reported 12.8M barrels of oil and 43.7M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 274 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 49.7K barrels injected in the 12 months reported through August 2025.

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