Cobb ET AL #20 (API 42-501-33286) is a plugged well in Yoakum County, plugged May 13, 2024, last operated by Occidental Permian Ltd..

The RRC has issued one drilling permit (amended once), issued September 25, 1987, permitted to 8,600 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, Glorieta, U. Clearfork C-1, L. Clearfork.

Its lease has reported 206K barrels of oil and 65.2K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

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