Better Oil Extraction Using CO2 With A New Additive
October 17, 2012 | 1 Comment
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 […]

Making CO2 Better for Oil Extraction
November 29, 2010 | 4 Comments
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 […]
