Carbon dioxide enhanced oil recovery (CO2-EOR) has been undergoing for four decades and is now a proven technology. CO2-EOR increases oil recovery, and in the meantime reduces the greenhouse gas emissions by capture CO2 underground. The objectives of this study are to improve the understanding of the mechanisms of CO2 flooding, and to investigate the feasibility of CO2-EOR in the East Texas Oil Field (ETOF) by conducting laboratory experiments. The laboratory experiments include phase behavior studies (such as slim tube tests and swelling/extraction tests) and core flooding tests. Initial laboratory experiments indicated that miscibility was not achievable at current reservoir conditions and the oil recovery was low. Besides the low oil recovery, severe core plugging and decrease in injectivity were found throughout the experiments. ETOF was not a recommended candidate for CO2-EOR currently. But further research could be done on developing new technology to reduce core plugging and well leaking, and finding more economically available CO2 sources.
