Aker Solutions and FSubsea have agreed to a joint venture, named FASTSubsea, to help operators increase oil recovery. High-concentration polymer flooding can improve oil-displacement efficiency but separation of oil/water mixture becomes more difficult because of emulsification. In this work, a case history of dehydration technology for HCPF production and lab investigation of emulsion behaviors are reviewed. The authors discuss the results of a pilot project to capture post-combustion CO2 for purposes of EOR. Produced water from chemical floods can cause problems for separation and water treatment equipment due to the polymers and surfactants used.
