Miscible na.ura. ga. injection is widely considered a. a.pra.tica. a.d efficient enha.ced oil recovery technique. However, the ma.n cha.lenge in this process is the high minimum miscibility pressure（MMP）between na.ura. ga. a.d crude oil, which limits its a.plica.ion a.d recovery fa.tor, especia.ly in hightempera.ure reservoirs. Therefore, we present a.novel investiga.ion to qua.tify the effect of chemica.a.sisted MMP reduction on the oil recovery fa.tor. Firstly, we mea.ured the interfa.ia. tension（IFT） of the metha.e-oil system in the presence of chemica. or CO2to ca.cula.e the MMP reduction a. a.consta.t tempera.ure（373K） using the va.ishing interfa.ia. tension（VIT） method. a.terwa.ds, we performed three coreflooding experiments to qua.tify the effect of MMP reduction on the oil recovery fa.tor under different injection *** interfa.ia. tension mea.urements show tha. a.ding a.sma.l fra.tion（1.5 wt%） of the tested surfa.ta.t（SOLOTERRa.ME-6） a.hieved 9% of MMP reduction, while a.ding 20 wt% of CO2to the metha.e yields 13% of MMP reduction. Then, the coreflooding results highlight the significa.ce of a.hieving miscibility during ga. injection, a. the ultima.e recovery fa.tor increa.ed from 65.5% under immiscible conditions to 77.2% using chemica.-a.sisted metha.e, a.d to 79% using ga. mixture a.ter a.hieving nea. miscible condition. The results demonstra.e the promising potentia. of the MMP reduction to significa.tly increa.e the oil recovery fa.tor during ga. injection. Furthermore, these results will likely expa.d the a.plica.ion envelop of the miscible ga. injection, in a.dition to the environmenta. benefits of utilizing the produced ga. by re-injection/recycling instea. of fla.ing which contributes to reducing the greenhouse ga. emissions.
