Carbon dioxide (CO2) has been used commercially to recover oil from geologic formations
by enhanced oil recovery (EOR) technologies for over 40 years. The US Department of …

Foam has been applied in enhanced oil recovery (EOR) for more than sixty years. The
surfactant-stabilized N 2/CO 2 foams are two of the most widely used foams in foam EOR …

Previously we showed that CO2 could be used to extract organic molecules from ionic
liquids without contamination of the ionic liquid. Consequently a number of other groups …

In recent years, green chemistry has become an area of significant research interest. It is
best defined as “the utilization of a set of principles that reduces or eliminates the use or …

Carbon dioxide (CO 2) has been utilized to recover the residual oil from the geological
reservoirs through enhanced oil recovery (EOR) methods for over 50 years. Despite its long …

The ongoing search for environmentally friendlier alternative to the organic solvents used in
chemical processes has led to the development of technologies based on supercritical …

It has long been recognized that there are synergies between EOR (enhanced oil recovery)
techniques, as is the case between low salinity waterflooding and polymer flooding. While …

CO2 injection is a promising method for enhanced oil recovery (EOR) in unconventional
shale reservoirs. In this work, we postulate that CO2 EOR may be improved by the …

Several commercially available and a few experimental, nonionic surfactants were identified
that are capable of dissolving in carbon dioxide (CO 2) in dilute concentration at typical …

High molecular weight associating random copolymers, such as poly (fluoroacrylate-
styrene)(polyFAST), are direct CO2 thickeners that can dissolve readily in CO2 and …
