Dawson County · Welch field · Shut In · Vertical
West Welch Unit #710 (API 42-115-30103) is a well in Dawson County operated by Hilcorp Energy Company, completed June 14, 1994 and listed as shut in on the RRC schedule, shut in November 1, 2025.
The RRC has issued one drilling permit, issued March 1, 1995, permitted to 4,982 ft.
It was permitted by Oxy USA Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
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.
