Goldsmith North Devonian Unit #4 (API 42-135-03155) is a well in Ector County operated by Octane Energy Operating LLC, completed December 27, 1953.
The RRC has issued one drilling permit, issued May 6, 2024, permitted to 7,790 ft.
It was permitted by Fivestones Energy LLC and has since transferred to Octane Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yates, Seven Rivers, Grayburg, San Andres.
Its 2 leases have reported 484K barrels of oil and 309K mcf of gas since January 1993, last reporting in July 2026. The leases carry 26 wells, so these are lease totals, not this well alone.
