Cwc Prentice Unit #30 (API 42-501-33004) is a well in Yoakum County operated by Occidental Permian Ltd., completed November 12, 1990 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued December 31, 1985, permitted to 6,855 ft.

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

Completion filings report 4 formation tops, including Rustler, San Andres, Glorieta, Clear Fork.

Its lease has reported 4.65M barrels of oil and 1.07M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 89 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 167K barrels injected in the 12 months reported through November 2025.

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

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.
