Goldsmith-Cummins /Deep/ Unit #420 (API 42-135-39197) is a well in Ector County operated by Formentera Operations LLC, completed November 24, 2006 and listed as shut in on the RRC schedule, shut in April 1, 2022.

The RRC has issued one drilling permit (amended once), issued September 19, 2006, permitted to 6,388 ft.

It was permitted by Anadarko Petroleum Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its lease has reported 10.2M barrels of oil and 28.1M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 396 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.
