Simulation results from OLGA and Multiflash software were integrated with physical particle movement models. In addition, a machine learning model was developed using the XGBoost and StackingCVRegressor libraries to predict the thickness and location of deposition in four selected wells.<\/p>\n<p>Conclusions:<\/p>\n<p>The used EOS models produced reliable and closely matched results. The SF model was adopted as the closest to real data and was used in sensitivity studies. The most influential factors in asphaltene deposition were found to be reservoir pressure, tubing diameter, and wellhead pressure. The developed model demonstrated high efficiency in enhancing production design and reducing the risk of tubing blockage caused by asphaltene buildup.<\/p>\n<p>After an in-depth scientific discussion by the examination committee, and following the student\u2019s defense and evaluation of the dissertation, the committee decided to award Ali Anwar Ali a Ph.D. in Petroleum Engineering, wishing him continued success in his academic and research career.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=&#8221;3&#8243; images=&#8221;7773&#8243; img_size=&#8221;large&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] On Thursday, February 13, 2025, the College of Engineering at the University of Baghdad held a public defense for &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.coeng.uobaghdad.edu.iq\/?p=7772\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":165,"featured_media":7774,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[14,31],"tags":[],"class_list":["post-7772","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-petroleum-engineering","category-thesis"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
