Pennzoil and Quaker State left the Venango area for Texas. After leaving the area they merged and stopped refining oil. They now concentrate on retail oil and automotive additives produced for them by other companies. As of 2007, the two companies only exist as brand names after the company disappeared because of successive mergers.

With global crude oil prices touching US$100 in early 2008, long-dormant interest reawakened in Venango County's remaining oil reserves, 70% undrilled by one estimate. High prices make less accessible oil deposits worth extracting. For instance, a Canadian firm proposed drilling several large mines and allowing oil to flood the tunnels.<ref>{{cite web
