S. Foster Gbsa Unit #109 (API 42-135-38772) is a well in Ector County operated by Oxy USA Inc., completed December 11, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 21, 2004, permitted to 4,650 ft.

It was permitted by Latigo Petroleum Texas, LP and has since transferred to Oxy USA Inc. on the wellbore schedule.

Completion filings report 3 formation tops, including Yates, Queen, Grayburg.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 17, 2008. 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.
