Witryna9 lip 2024 · Gas flooding in reservoirs is a well-known secondary recovery mechanism and also a gas storage method in the world (Bybee 2001; Azin et al. 2008; Mohammadi et al. 2011; Yuncong et al. 2014; Agrawal et al. 2016; Kumar et al. 2024).Comprehensive analysis of miscible/immiscible gas injection has been undertaken by many … WitrynaIt was found that comparing the tertiary gas floods only on the basis of recovery yielded misleading conclusions. However, when oil recovery per unit volume of gas injection was used as a parameter to evaluate the floods, miscible gas floods were found to be more effective (recovering 60-70% more oil) than immiscible floods. The WAG
