Dawson County · Welch field · Injection · Vertical

West Welch Unit #719 (API 42-115-32651) is a well in Dawson County operated by Hilcorp Energy Company, completed January 2, 2023 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued December 27, 1990, permitted to 4,965 ft.

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

Completion filings report 2 formation tops, including Yates, San Andres.

Its lease has reported 20.4M barrels of oil and 7.45M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 687 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 36.5K barrels injected in the 12 months reported through August 2025.
