Ector County · Cowden South field · Shut In · Vertical
Foster Gbsa Unit #313 (API 42-135-39026) is a well in Ector County operated by Oxy USA Inc., completed June 23, 2022 and listed as shut in on the RRC schedule, shut in February 1, 2021.
The RRC has issued one drilling permit (amended once), issued February 13, 2006, permitted to 4,625 ft.
It was permitted by Latigo Petroleum Texas, LP and has since transferred to Oxy USA Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Rustler, Yates, Queen, Grayburg.
Its lease has reported 1.48M barrels of oil and 585K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 131 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 22, 2007. Density, 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.
