East Cowden (Grayburg) Unit #81 (API 42-135-35646) is a well in Ector County operated by GL Energy Operating LLC, completed April 2, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 18, 1987, permitted to 4,695 ft.
It was permitted by Conoco Inc. and has since transferred to GL Energy Operating LLC on the wellbore schedule.
Its lease has reported 10.4M barrels of oil and 3.6M mcf of gas since January 1993, last reporting in July 2026. The lease carries 92 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 266K barrels injected in the 12 months reported through November 2025.
