Different cases were analyzed using the CMG simulator where consideration was given to cases of single as well as multiple producing horizontal wells. The model built considered both the basic reservoir model as well as geo-mechanical models. The individual cases considered included different geo-mechanical properties of the producing formation these properties however include frictional angle, cohesion factor, Young Modulus as well as Poison ratio. Models analyzed involved the effect of these different geo-mechanical properties on the maximum stress in the producing formations as well as salty formations. However, for the stress analysis, Mohr Coulomb model was used.<\/span><br \/>\n<span style=\"color: #000000;\">Factors that majorly affected maximum stress mostly were found to be frictional angle and the cohesion factors, formation with higher porosity and permeability having higher production developed higher maximum stress compared to low producing zones also high frictional angle at producing formation resulted averagely into lower maximum stress build up while low frictional angle resulted into higher maximum stress build up. Also, formation with high cohesion factor shows higher maximum stress build up while those with low cohesion factor shows lower maximum stress build up.<\/span><br \/>\n<span style=\"color: #000000;\">A general trend however observed in all the cases indicated that whatever geo-mechanical factor or combination of these factors satisfy high production rate will generate higher stress build up both around the wellbore and the producing formation.<\/span><br \/>\n<img loading=\"lazy\" class=\"wp-image-60449 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file.jpeg\" alt=\"\u56fe\u793a, \u7ef4\u6069\u56fe\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" width=\"768\" height=\"790\" \/><br \/>\n<img class=\"wp-image-60450 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-54.png\" alt=\"\u8868\u683c\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60451 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-55.png\" alt=\"\u6587\u672c, \u4fe1\u4ef6\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60452 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-56.png\" alt=\"\u56fe\u5f62\u7528\u6237\u754c\u9762\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><br \/>\n<img class=\"wp-image-60453 aligncenter\" src=\"http:\/\/learncmg.cn\/wp-content\/uploads\/2023\/05\/unnamed-file-57.png\" alt=\"\u56fe\u8868, \u6811\u72b6\u56fe\n\u63cf\u8ff0\u5df2\u81ea\u52a8\u751f\u6210\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u672c\u8bba\u6587\u7814\u7a76\u4e86\u58a8\u897f\u54e5\u6e7eMars-Ursa\u76c6\u5730\u7684\u6c34\u5e73\u4e95\u7b52\u5b8c\u6574\u6027\u6216\u7a33\u5b9a\u6027\uff0c\u5229\u7528\u8be5\u9ad8\u4ea7\u5730\u5c42\u7684\u4e0d\u540c\u5730\u8d28\u529b\u5b66\u7279\u6027<span class=\"more-link\"><a href=\"http:\/\/learncmg.cn\/?p=60448\">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":[323,397],"_links":{"self":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/60448"}],"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=60448"}],"version-history":[{"count":0,"href":"http:\/\/learncmg.cn\/index.php?rest_route=\/wp\/v2\/posts\/60448\/revisions"}],"wp:attachment":[{"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=60448"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=60448"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/learncmg.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=60448"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
