For the Bakken system, reservoir studies involving the fluid flow and recovery mechanism cannot be fully understood without resolving this uncertainty. Performance-anomalies in the GOR trends of the production-history of the Middle Bakken wells in the Reunion Bay, Sanish, Parshall and the Elkhorn-Ranch fields indicate the possibility of the anticipated contribution.<br \/>\nQuantifying the U&amp;L Shale contribution requires knowledge of the mechanism of fluid storage and flow in the liquid rich shale systems. For the U&amp;L Shale, adsorption is considered as the significant mode of fluid storage, and the process of diffusion is considered crucial for the matrix-to-fracture fluid transfer. The governing mathematical equations for desorption and diffusion was adopted from the shale gas systems. These equations are utilized in CMG\u2122\u2019s compositional simulator GEM\u2122 to propose a reservoir simulation-based quantification scheme for the U&amp;L Shale contribution.<br \/>\nThrough the sensitivity analyses, the effect of variation in the parameters of the U&amp;L Shale, the Middle Bakken layer and the hydraulic fracture is investigated. Utilizing the ranges of these parameters, the U&amp;L Shale layers are found to contribute from 12% to 52% of the cumulative production from a Middle Bakken well, whereas, the mean contribution is 40%. Relative sensitivity study suggested that the U&amp;L Shale production contribution is the most sensitive to the U&amp;L Shale matrix parameters, such as total organic carbon (TOC, wt.%) and molecular diffusion coefficients. The TOC controls the desorption-parameters; therefore, the findings suggest that the phenomena of desorption and diffusion are expected to play a crucial role in the anticipated production-contribution.<br \/>\n<img class=\"wp-image-57859\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-45.png\" alt=\"\u56fe\u8868, \u6298\u7ebf\u56fe\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-57860\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-46.png\" alt=\"\u56fe\u8868\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-57861\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-47.png\" alt=\"\u56fe\u793a\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-57862\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-48.png\" alt=\"\u56fe\u793a\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-57863\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-49.png\" alt=\"\u56fe\u793a\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-57864\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2022\/11\/unnamed-file-50.png\" alt=\"\u8868\u683c\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Upper and Lower Bakken Shale Production Contributi<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=57858\">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":[55],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/57858"}],"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=57858"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/57858\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=57858"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=57858"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=57858"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
