Carbon dioxide oil extraction research. Professor Julian Eastoe working on research into the use of carbon dioxide to extract oil. This work involves the development of a soap-like additive that turns liquid carbon dioxide (CO2) into a solvent that can be pumped underground under high pressure to extract oil from underground reserves. The additive is a hydrocarbon surfactant called TC14. A neutron source was used to study the properties of the surfactant as it interacts with liquid CO2. Photographed in 2012, at the University of Bristol, UK.
