Injection of CO<sub>2<\/sub>\u00a0can enhance oil recovery by reducing oil viscosity and improving overall fluid mobility. However, several problems are associated with CO<sub>2<\/sub>\u00a0injection such as viscous fingering, gravity override, and CO<sub>2<\/sub>\u00a0channeling that results in early gas breakthrough, low sweep efficiency, and low ultimate oil recovery. In this study, dual benefits of CO<sub>2<\/sub>\u00a0injection are presented: enhancing oil recovery and sequestering carbon dioxide. In this work, different scenarios of field scale simulation were conducted to evaluate oil recovery during CO<sub>2<\/sub>\u00a0injection, and the CMG (Computer Modeling Group) software package was used. Three main scenarios were examined which are CO<sub>2<\/sub>\u00a0injection into the reservoir, CO<sub>2<\/sub>\u00a0injection into the aquifer, and CO<sub>2<\/sub>\u00a0injection into the aquifer followed by waterflooding. Also, three well configurations were utilized\u2014all injectors and producers are drilled vertically, all wells are drilled horizontally, and vertical injectors and horizontal producers are used. Therefore, the oil recovery profiles were examined for nine scenarios over a 20-year period. In all simulated models, CO<sub>2<\/sub>\u00a0injection was started at the residual oil saturation (S<sub>or<\/sub>) conditions, to represent the cases of depleted oil reservoirs. The results indicated that the highest oil recovery of 73% of the original oil-in-place (OOIP) can be achieved by injecting CO<sub>2<\/sub>\u00a0into the reservoir, utilizing vertical injectors and producers. While injecting CO<sub>2<\/sub>\u00a0into aquifers can significantly enhance oil recovery by around 68\u201370% of the OOIP, using horizontal wells can provide more oil recovery (67.7%) than that using vertical wells (54.8%), in the same conditions. Moreover, around 7,928 tons of carbon dioxide can be sequestered in underground formations, on average. Finally, CO<sub>2<\/sub>\u00a0injection outperformed the conventional waterflooding, where 68 and 12% of the OOIP were obtained, respectively. Overall, injection of CO<sub>2<\/sub>\u00a0into the depleted reservoir can provide dual benefits of CO<sub>2<\/sub>\u00a0sequestration and improved oil recovery. CO<sub>2<\/sub>\u00a0can be injected into the water zone resulting in a slow release of CO<sub>2<\/sub>\u00a0which will reduce the fluid viscosity, enhance oil recovery, and reduce the greenhouse effect.<\/span><br \/>\n<span style=\"color: #000000;\"><img class=\"wp-image-61880 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/word-image-61878-1.png\" \/><\/span><br \/>\n<span style=\"color: #000000;\"><img class=\"wp-image-61881 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/unnamed-file-19.png\" alt=\"\u56fe\u5f62\u7528\u6237\u754c\u9762, \u56fe\u8868, \u6298\u7ebf\u56fe\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><\/span><br \/>\n<span style=\"color: #000000;\"><img class=\"wp-image-61882 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/11\/unnamed-file-20.png\" alt=\"\u56fe\u8868\n\u4e2d\u5ea6\u53ef\u4fe1\u5ea6\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dual Benefits of Enhanced Oil Recovery and CO2\u00a0Seq<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=61878\">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":[251],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/61878"}],"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=61878"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/61878\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=61878"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=61878"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=61878"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
