Enhanced Oil Recovery EOR Course

Intorduction

Enhanced oil recovery, additionally referred to as tertiary recovery, is the extraction of crude oil from an oil subject that can not be extracted otherwise. EOR can extract 30% to 60% or extra of a reservoir`s oil, in comparison to 20% to 40% the use of number one and secondary recovery. According to US Department of Energy, carbon dioxide and water are injected along side one in all 3 EOR strategies: thermal injection, gas injection, and chemical injection. More advanced, speculative EOR strategies are every now and then referred to as quaternary recovery.
