Goldsmith-Cummins /Deep/ Unit #186 (API 42-135-35367) is a plugged well in Ector County, plugged June 4, 2024, last operated by Formentera Operations LLC.

The RRC has issued one drilling permit, issued December 5, 1986, permitted to 6,600 ft.

It was permitted by Arco Oil & Gas CO. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 5 formation tops, including Yates, San Andres, Goldsmith 5600, Tubb.

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.
