South Welch Unit #1519 (API 42-115-32739) is a well in Dawson County operated by Hilcorp Energy Company, completed May 20, 1993 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued November 30, 1992, permitted to 4,993 ft.

It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 4 formation tops, including Rustler, Yates, Queen, San Andres.

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