Prentice Southwest Unit #86 (API 42-501-32635) is a well in Yoakum County operated by Occidental Permian Ltd., completed January 27, 2016 and listed as shut in on the RRC schedule, shut in December 1, 2015.

The RRC has issued one drilling permit, issued June 14, 1984, permitted to 6,845 ft.

It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.

Completion filings report 5 formation tops, including Rustler, San Andres, Gloreita G-1, Glorieta.

Its lease has reported 5.14M barrels of oil and 1.94M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 124 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

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 Oct 6, 2021. 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.
