Ector County · Goldsmith (Clear Fork) field · Shut In · Vertical
Goldsmith-Cummins /Deep/ Unit #409 (API 42-135-39179) is a well in Ector County operated by Formentera Operations LLC, completed November 21, 2006 and listed as shut in on the RRC schedule, shut in May 1, 2023.
The RRC has issued one drilling permit, issued August 29, 2006, permitted to 6,567 ft.
It was permitted by Anadarko Petroleum Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 5 formation tops, including T Anhydrite & B Redbed, Base Of Salt/Top Yates, San Andres, Clear Fork.
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.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 19, 2007. Cased hole, Gamma ray, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
