The abnormal climate change has made the reduction of CO2 emission that received worldwide attention. The integration of CO2 capture-sequestration application for enhanced oil recovery (EOR) technology will be the new trend. Several scholars have applied microfluidics in CO2 capture, oil and gas analysis, and CO2 sequestration. The mass transfer process for CO2 capture can be intensified owing to the large specific surface/volume ratio and high contact area in microchannels. The small amount of feeding volumes of oil and gas samples and the quick response for the analysis make the microfluidics a promising tool for the oil and gas analysis. Moreover, microfluidics can reveal the transport mechanism at microscale for multiphase interfacial phenomena in microchannels within porous media during the CO2 flooding process in line with the pressure, temperature, and material properties of the rock within the oil reservoir. This chapter will elaborate the progress of the application of microfluidic technology in the utilization of CO2, including the mechanism of mass transfer for CO2 in microreactors, the advantages of microfluidics in oil and gas analysis, and the fundamentals of microfluidics in CO2 flooding, oil recovery improvement, and CO2 sequestration.
