East Cowden (Grayburg) Unit #74 (API 42-135-35279) is a well in Ector County operated by GL Energy Operating LLC, completed May 7, 2012 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1986 and 1987, permitted to 4,707 ft.
It was permitted by Conoco Inc. and has since transferred to GL Energy Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Grayburg.
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.
