Mixing issues in CO2 flooding: comparison of compositional and extended black-oil simulators
Extended black oil simulators provide a convenient model for CO2-EOR flooding projects and are preferred because of less data requirements compared with compositional simulation models, therefore, underlying principles of extended black-oil simulation models deserve scrutiny. The main objective of this study is to investigate the impact of different numerical solution techniques on modeling of oil recovery by CO2 flooding and compare extended black-oil and compositional simulators in order to examine the capabilities of these simulators with an emphasis on mixing mechanism of oil and CO2. Thus, ...
