摘要

CO _( 2 ) foams are able to improve oil recovery by blocking high permeable channels and mobility control which are the main challenges of conventional CO _( 2 ) flooding. Because of the specific properties of CO _( 2 ) , CO _( 2 ) foams are less stable than N _( 2 ) foams. Therefore, introducing stabilizing agents for application in harsh reservoir conditions is highly crucial. Some chemicals such as different surfactants and polymers have been proposed for enhancing the stability of CO _( 2 ) foams, but they lose their performance at elevated temperatures, pressures, and salinities. Many researchers have proposed using nanoparticles as CO _( 2 ) -foams stabilizers since their thermal and mechanical stability make them better stabilizers than polymers and surfactants, and they can resist high pressures, temperatures, salinities, and shear of reservoir conditions. In this study, a review is done on the most recent studies performed for investigating the performance of various types of nanoparticles for CO _( 2 ) -foams stabilization at different environmental conditions. The main mechanisms involved, the most important stability tests for nanoparticles and CO _( 2 ) foams, and comparison between nanoparticles and other stabilizing agents are included and explained in this review. Finally, one of the most important parameters that can control and limit the use of nanoparticles-stabilized CO _( 2 ) foams for enhanced oil recovery process, i.e., transport of nanoparticles in porous media, is discussed in detail.
