Ector County · Cowden South field · Shut In · Vertical
S. Foster Gbsa Unit #310 (API 42-135-38846) is a well in Ector County operated by Oxy USA Inc., completed February 12, 2013 and listed as shut in on the RRC schedule, shut in February 1, 2011.
The RRC has issued one drilling permit, issued February 18, 2005, permitted to 4,715 ft.
It was permitted by Latigo Petroleum Texas, LP and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Queen, 4366, Grayburg, San Andres.
Its lease has reported 675K barrels of oil and 307K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
