Oil extraction technology marches on.   University of Pittsburgh engineers show crude oil extraction could be improved significantly and accessible domestic oil reserves could be expanded with their new economical CO2 thickener. Most of the current U.S. oil-extraction methods involve oil being “pushed” from underground layers of porous sandstone or limestone reservoirs using a first-water-then-CO2 method […]

Researchers have developed a soap-like additive for CO2 that turns it into a viable solvent for commercial-scale enhanced oil recovery to increase the amount of crude oil that can be extracted from oil fields.  This might be a major step in oil field recovery, which could vastly expand the world reserves. At the UK’s University […]
