Ector County · Cowden North field · Injection · Vertical
East Cowden (Grayburg) Unit #71 (API 42-135-35283) is a well in Ector County operated by GL Energy Operating LLC, completed October 17, 1986 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits in 1986, permitted to 4,700 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 volume in April 2026. The lease carries 92 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 315 barrels injected in the 12 months reported through November 2025.
