Cockburn H. C. #63D (API 42-481-02627) is a plugged well in Wharton County, plugged April 3, 2018, last operated by White Oak Operating Company LLC.
The RRC has issued 3 drilling permits between 1989 and 2006, permitted to 6,322 ft.
It was permitted by Kcs Resources, Inc. and has since transferred to White Oak Operating Company LLC on the wellbore schedule.
Its 4 leases have reported 6.54M barrels of oil and 6.13M mcf of gas since January 1993, last reporting in July 2026. The leases carry 145 wells, so these are lease totals, not this well alone.
