Pore Scale Investigations of Simultaneous Enhanced Oil Recovery and Carbon Sequestration


EMSL Project ID
45993

Abstract

Two researchers from the Chinese Academy of Sciences (CAS) recently visited the EMSL on a rapid access proposal to investigate how detailed displacement experimentation can be used to improve the understanding of concurrent CO2-Enhanced Oil Recovery (EOR) and Carbon Capture and Storage (CCS) at the pore scale. Due to time limitations, only a preliminary set consisting of two-phase (brine-CO2) experiments could be completed. The results were promising and a culminating set of three-phase (brine-oil-CO2) experiments need to be conducted to complete the experimental data set. It is proposed to conduct these experiments in FY12 and develop a peer-reviewed journal paper based on the collaborative effect with CAS. Micromodel displacement studies where oil is removed by supercritical CO2 will be conducted in EMSL's new microfluidics laboratory.
