Polymer has shear rate and temperature-dependence viscosity which is substantially different behaviorfrom water. Any calculation related to injection performance should consider this behavior. Injector should be organized to achieve the desired injection rate without any issue. The easiest approach to design the optimum injector is using IPR-TPR method. Therefore, in this paper, we develop Non-Newtonian IPR-TPR method to achieve optimum completion design of injector. The IPR equation is built using modified Darcy equation for Non-Newtonian fluid. The TPR equation is developed using Dodge and Metzner (1959) with linear temperature distribution. This approach produces the established rate of polymer injection, which is used to evaluate the completion strategy in injector. We used case study of T-048 – T-012 injector-producer in Tanjung Field Zone-C, Indonesia with 500 and 2,000 ppm HPAM polymer. Simulation results show that there exists changing process from shear thinning to Newtonian along the tubing because of temperature and injection velocity while only Newtonian behavior occurs in near wellbore for 500 ppm injection case. Smaller tubing OD produces higher effective injection rate than the bigger one. The 2,000 ppm polymer cannot enter the reservoir due to bottomhole pressure reaches the fracture presure.Finally, smaller tubing OD (below 2.875 in) is suitable in Tanjung Field Zone-C for 500 ppm polymer injection. 2,000 ppm polymer cannot be deployed and needed further evaluation.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Injection performance,Injectivity,Linear temperature distribution,Modified darcy equations,Newtonian behavior,Non-newtonian,Non-Newtonian fluids,Temperature dependence[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Injectivity,IPR,Non-Newtonian,Polymer,TPR[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.2118/186259-ms[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
