Ector County · Cowden South field · Shut In · Vertical
West Grayburg Unit #28 (API 42-135-32725) is a well in Ector County operated by Occidental Permian Ltd., completed October 23, 2016 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued July 29, 1977, permitted to 4,300 ft.
It was permitted by Amoco Production Company and has since transferred to Occidental Permian Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Queen, Grayburg.
Its lease has reported 951K barrels of oil and 257K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 41 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
