What Does Enhanced Oil Recovery (EOR) Mean?
Enhanced oil recovery (EOR) refers to several highly technical methods that are implemented to increase the quantity of oil extracted from an oil field. EOR can increase oil extraction and recovery rate volumes by up to 60% compared to traditional primary and secondary recovery practices.
The enhanced oil recovery stage involves changing the chemical and/or physical properties of the petroleum deposits to be extracted to ease their recovery. This includes the introduction of chemicals, fluids or heat to generate reactions within the oil wellbore or reserve. The three main forms of EOR are gas injection, chemical injection and heat injection.
