Ector County · Cowden North field · Vertical
East Cowden (Grayburg) Unit #70 (API 42-135-35364) is a plugged well in Ector County, plugged September 14, 2023, last operated by GL Energy Operating LLC.
The RRC has issued 2 drilling permits (amended once) 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 3 formation tops, including Yates, Grayburg, San Andres.
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.
