Dawson County · Welch field  · Vertical

West Welch Unit #4617 (API 42-115-32471) is a plugged well in Dawson County, plugged October 4, 2024, last operated by Oxy USA Wtp Eor LLC.

The RRC has issued one drilling permit (amended once), issued January 22, 1988, permitted to 5,000 ft.

It was permitted by Cities Service Oil & Gas Corp. and has since transferred to Oxy USA Wtp Eor LLC on the wellbore schedule.

Completion filings report one formation top, including San Andres.

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

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