Various dynamic loads work on casing/liner, including internal loads such as wellbore condition (e.g., dogleg severity/DLS, lost circulation) and external loads such as lithology and impact from nearby wells (production and injection). The internal and external loads influence each other and should be calculated precisely, iteratively, and continuously for casing/liner design during the lifetime of the well. Theoretically, there are many guidelines for loads calculation, such as the New Zealand Standard (NZS 2403:2015). Unfortunately, they are very general and cannot be directly applied in field cases, particularly in Indonesia, thus calculation improvement is required. This study focused on the evaluation of lower liner in a geothermal injection well HCE5A in vapor dominated reservoir with temperature up to 285 °C in Dieng Field, operated by PT Geo Dipa Energi, Indonesia. The loads experienced by lower injection liner were re-constructed and re-calculated. The maximum loads in each phase of operations were considered in the re-calculation. The result showed that failure occurred at lower injection liner. Besides, the methodology developed in this study is used as a standard operating procedure (SOP) for next injection well construction in Dieng Field.[/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]Indonesia,Injection wells,Iteration,Liner,Vapor dominated[/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]Geothermal injection well,Indonesia,Iteration,Liner,Vapor dominated reservoir[/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/10.1016/j.renene.2019.12.085[/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]
