West Rkm Unit #321 (API 42-219-37252) is a plugged well in Hockley County, plugged June 14, 2023, last operated by Occidental Permian Eor LLC.
The RRC has issued one drilling permit (amended once), issued July 20, 2012, permitted to 5,400 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Grayburg, San Andres.
Its lease has reported 23.1M barrels of oil and 11M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 304 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Sep 15, 2014. 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.
