Seminole San Andres Unit #3910R (API 42-165-37478) is a well in Gaines County operated by Oxy USA Inc., completed April 9, 2024 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued October 3, 2011, permitted to 5,640 ft.

It was permitted by Hess Corporation and has since transferred to Oxy USA Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Rustler, Yates, Seven Rivers, Grayburg.

Its lease has reported 280M barrels of oil and 328M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 710 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 95.7K barrels injected in the 12 months reported through October 2025.

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

2 logs loaded from the RRC's log index, the latest received May 9, 2013. Cased hole, 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.
