Cyclic CO<sub>2<\/sub>\u00a0injection is an enhanced oil recovery process consisting of injection, shut-in, and production. The study of cyclic CO<sub>2<\/sub> injection and hydrocarbon recovery in ultra-low permeability reservoirs is mainly a function of rock, fluid, and operational parameters. CMG-GEM was used to study several design parameters of cyclic CO<sub>2<\/sub>\u00a0injection process to distinguish the parameters with maximum effect on the oil recovery and to comprehend the behavior of cyclic CO<sub>2<\/sub>\u00a0injection in tight reservoir. On the other hand, permeability reduction induced by asphaltene precipitation is one of the major issues in the oil industry due to its plugging onto the porous media which reduces the oil productivity. In addition to asphaltene deposition, solubility of CO<sub>2<\/sub>\u00a0in the aquifer is one of the safest and permanent trapping techniques when considering CO<sub>2<\/sub>\u00a0storage mechanisms in geological formations. However, the effects of the above uncertain parameters on the process of CO<sub>2<\/sub>\u00a0enhanced oil recovery have\u00a0not\u00a0been understood systematically. Hence, it is absolutely necessary to study the most significant parameters which dominate the process. The main objective of this study is to improve techniques for designing cyclic CO<sub>2<\/sub>\u00a0injection process while considering the effects of asphaltene deposition and solubility of CO<sub>2<\/sub> in the brine in order to prevent asphaltene precipitation, minimize CO<sub>2<\/sub>\u00a0emission, optimize cyclic CO<sub>2<\/sub>\u00a0injection, and maximize oil production.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/06\/150.png\" width=\"709\" height=\"564\" \/><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Simulation Study of Asphaltene Deposition and Solu<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=19248\">Continue Reading<\/a><\/span><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[159],"tags":[263,477],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/19248"}],"collection":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=19248"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/19248\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=19248"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=19248"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=19248"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
