Yoakum County · Wasson 72 field · Injection · Vertical
Yoakum Wasson Clearfork Unit #2711WY (API 42-501-32171) is a well in Yoakum County operated by Occidental Permian Ltd., completed April 25, 1997 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued December 7, 1981, permitted to 7,580 ft.
It was permitted by Shell Oil Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Glorieta.
Its lease has reported 15.1M barrels of oil and 5.22M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 269 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 118K barrels injected in the 12 months reported through September 2025.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 18, 2021. 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.
