= average porosity of formation, dimensionless. Soi = initial oil saturation in pore space, fraction. Boi = oil formation volume factor at initial reservoir pressure, reservoir barrel/stock tank barrel. Recovery factors are a function of the fluid displacement and areal and vertical sweep efficiencies. Carbon dioxide (CO2) has been used in commercial manner for decades to increase recovery from oil fields in a process called "CO2-enhanced oil recovery" or CO2-EOR. Harnessing this practice to qualify as permanent storage of CO2 is possible, but requires a major paradigm shift from conventional EOR to "EOR+", including additional activities. The enhanced oil recovery process consists of drilling new injection wells into and around the reservoir through which fluids or gases are injected under high pressure from the production platform. This either directly increases the reservoir pressure or gathers the oil from the surrounding area to the reservoir for extraction. CO2 enhanced oil recovery [ Oil and Gas Production Plants ] [ ENERGY ] Carbon capture and storage (CCS) is a technology to recover CO 2 from fossil fuel power plants and factories and store them underground, shutting out contact with the atmosphere. Carbon Dioxide Enhanced Oil Recovery Oil and water form separate phases when mixed. Oily surfaces can be cleaned if a solvent is used that is completely miscible with the oil. Cross-section illustrating how carbon dioxide and water can be used to flush residual oil from a subsurface rock formation between wells. Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery.
23 Jun 2016 CO2-EOR has been recognized as the second largest EOR process in the world, after the thermal processes used in heavy oil fields [8].

Cross-section illustrating how carbon dioxide and water can be used to flush residual oil from a subsurface rock formation between wells. Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. Enhanced oil recovery, also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, there are three primary techniques for EOR: thermal, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery.
