Edwin Cox #1 (API 42-317-31936) is a plugged well in Martin County, plugged March 10, 2023, last operated by Diamondback E&P LLC.
The RRC has issued 2 drilling permits between 1977 and 2017, permitted to 12,000 ft.
It was permitted by Qep Energy Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Its 2 leases have reported 54.8K barrels of oil and 80 mcf of gas since January 1993, last reporting in June 2023. The leases carry 2 wells, so these are lease totals, not this well alone.
