“…Both theoretical calculation and laboratory experimental methods have been used to obtain the MMP of CO 2 -crude oil (Zendehboudi et al, 2013;Ahmadi et al, 2015;Ahmadi et al, 2017;Ahmadi et al, 2018). Theoretical calculation methods mainly include empirical formulae (Yellig and Metcalfe, 1980), multiple contacts (Adekunle and Hoffman, 2016), numerical simulations (Ekechukwu et al, 2020), and equation of states (Karkevandi-Talkhooncheh et al, 2017), etc., because the application range of different calculation methods is different, and the results are greatly affected by parameters. The experimental measurement methods mainly include the slim tube test (STT) (Flock and Nouar, 1984;Mogensen, 2016), rising bubble apparatus (RBA) (Christiansen and Haines, 1987;Novosad et al, 1990;Czarnota et al, 2017), vanishing interfacial tension technique (VIT) (Rao, 1997;Saeedi Dehaghani and Soleimani, 2020), X-ray computerized scanner (Liu et al, 2015;Ahmad et al, 2016), magnetic resonance imaging technique (MRI) (Liu et al, 2016;Karkevandi-Talkhooncheh et al, 2018), core displacement experiment (Zhang and Gu, 2015;Ennin and Grigg, 2016), and so on.…”
