London Ollie #10 (API 42-355-30292) is a plugged well in Nueces County, plugged February 9, 2010, last operated by CG Technical Operating CO LLC.
The RRC has issued one drilling permit, issued September 19, 2007, permitted to 4,420 ft.
It was permitted by Extex Operating Company and has since transferred to CG Technical Operating CO LLC on the wellbore schedule.
Its 2 leases have reported 260K barrels of oil and 140 mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
