Geologic Criteria gives fast and good prediction of local capillary traps in the CO2 swept zone during injection.The extended connectivity analysis shows a good match of CO2 plume computed by the full-physics simulation (CMG-GEM).&nbsp;Here exists a threshold Dykstra-Parsons coefficient, below which low injection rate gives rise to more LCT; whereas higher injection rate increases LCT in heterogeneous reservoirs.&nbsp;Both the geologic criteria and connectivity analysis are very fast; therefore, the integrated methodologies can be used as a quick tool to estimate local capillary trapping at the field scale.<\/p>\n<p><strong>Keyword:<\/strong> CCUS, CO2, GEM, local capillary traps, Dykstra-Parsons coefficient<\/p>\n<p>\u8fc7\u7a0b\uff1a\u4e8c\u6c27\u5316\u78b3\u54b8\u6c34\u5c42\u6ce8\u5165<\/p>\n<p>\u6a21\u62df\u5668\uff1aGEM<\/p>\n<p><img loading=\"lazy\" class=\" wp-image-16199 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/02\/4-300x227.png\" alt=\"\" width=\"670\" height=\"507\" data-mce-src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/02\/4-300x227.png\"\/><\/p>\n<p><img loading=\"lazy\" id=\"thepasted-1\" class=\"aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/03\/Disclaimer.jpg\" width=\"545\" height=\"83\" data-mce-src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/03\/Disclaimer.jpg\"\/><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Field Scale Modeling of Local Capillary Trapping d<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=15805\">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":[251,387,432,463],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/15805"}],"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=15805"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/15805\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=15805"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=15805"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=15805"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
