One application where liquid CO2 has found success is enhanced oil recovery (CO2-EOR) of crude oil from porous rocks. However, a significant disadvantage of using CO2 in EOR is the fact that the very low viscosity does not readily facilitate transport to oil bearing rock, but rather through porous media (fingering), which offers the pathway of least resistance [1]. There a great deal of interest in developing systems that can enhance CO2 viscosity, and this proposal addresses this issue with a new approach to enhancing CO2 viscosity. The research has received external publicity (e.g. and UK Government agency UK Trade & Investment UKTI http://www.ukti.gov.uk/pt_pt/investintheuk/sectoropportunities/energy/item/125685.html). This proposal is associated with EPSRC projects Reverse engineering and synthesis of self-assembling photo-responsive surfactants for CO2 Solubilization.
