M. Almahdawi<\/strong>. The examination committee consisted of<strong> Prof. Dr.Rafid kadhim Abbas <\/strong>as Chairman and the membership of <strong>Assistant prof .Dr. Rwaida Kaiser Abdul Majeed <\/strong>and<strong> Assistant prof .Dr.\u00a0 Nagham j. Al-Ameri <\/strong>. The thesis was summarized as follows:<\/p>\n<p>&nbsp;<\/p>\n<p>The objective of this study is to enhance the drilling fluid used in reservoirs in order to reduce damage. This will be achieved by comparing the performance of RDF and\u00a0 RDF with NPS with the traditional drilling fluid currently used in the field. The study focused on the Mishrif formation, specifically a horizontal drilling of 3000m within the reservoir.\u00a0 In other words, to get better properties of drilling fluids prepared with Fe<sub>2<\/sub>O<sub>3<\/sub>\u00a0 NP<sub>S<\/sub> and ZnO NP<sub>S<\/sub>\u00a0 that can perform better performance and thermal resistance up to 400F\u030a.In this study laboratory tests were used and compared with field data from the southern oil field (Basra-Iraq).In both freshwater and saltwater drilling fluids, Nano particles materials ( NP<sub>S<\/sub>)\u00a0 showed the best improvement in the filtration parameters, rheological properties, and thermal stability . All of the results that obtained in this work will help to increase the stability of the produced drilling fluids overall. The effect of different concentrations of the ZnO \u00a0and Fe<sub>2<\/sub>O<sub>3<\/sub> NPs was tested on rheological, filtration properties and thermal stability of RDF. Thermal stability of the mud was tested with the temperatures reaching 400F\u030a. Results showed that nano-based mud possess more stable rheological behaviour at elevated temperatures compared to RDF.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Adding Fe2O3 and ZnO NPs at concentrations of \u00a00.5, 0.75, 1, and 1.5 \u00a0g \/ml to RDF, The reduction in plastic viscosity (PV) was controlled by about 20% using Nanomaterials. Also, from the results, it can be seen that the rate is more constant, with a smooth decrement curve in yield point ( YP), \u00a0the percentage of decreasing in (YP) at 400F\u030a when adding Fe2O3 and ZnO NPs. is 8 and 12% respectively.\u00a0Also, it enhances the reduction of gel strength at 10 sec and 10 min. Finally, there is no trace of thermal degradation.. The addition of nanoparticles also enhanced filtering characteristics. Fluid loss rate was reduced by 40% when adding Fe2O3 and 30% when adding ZnO NPS. The improved rate of fluid loss has a positive impact on the efficiency of drilling operations by reducing the risk of formation damage \u00a0caused by filtrate invasion<sub>.<\/sub> The smooth, efficient surface of the mud cakes was enhanced by the inclusion of ZnO and Fe2O3 NPs, which also decreased differential sticking. Overall, when compared to RDF with NP<sub>S<\/sub> and RDF without NP<sub>S<\/sub>.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=&#8221;3&#8243; images=&#8221;5730&#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] \u00a0 The Petroleum Engineering Department at the College of Engineering, University of Baghdad, held a M.Sc. thesis examination titled: &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.coeng.uobaghdad.edu.iq\/?p=5728\"><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":5729,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[14,31],"tags":[],"class_list":["post-5728","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 v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Examination of M.Sc.
