... recovery in these complex plays is inevitable. In shale oil reservoirs, EOR is relatively novel compared with in conventional oil reservoirs. The most investigated technique among EOR methods to be applied in shale oil reservoirs is injecting miscible gases which mainly include CO 2 , N 2 and enriched...

... . Abstract The most commonly used technology for development of unconventional liquid-rich and light oil reservoirs is horizontal wells combined with large multi-stage hydraulic fracture treatments. However, even with these technological advancements, primary recovery factors are generally less than 10...
