From a number of tests conducted it was found that are presence of sand problems in this field especially in well G1 so that several studies were conducted. From the results of the study, it is determined that the use of Frac pack is one of the most appropriate ways, besides controlling sand problems, it also increases gas production on field X. The Frac pack method is a well stimulation by combining gravel pack to control the sand problems with hydraulic fracturing which is designed to have high conductivity to increase productivity over the well. In this paper, a calculation model is developed to find out the optimum fracture half length, fracture width and also the pumping schedule of the Frac pack with sensitivity of proppant concentration. Then the results will be compared with existing commercial software. The challenge faced in frac pack modeling for well G1 is large permeability so that the possibility of leakage occurring is greater and then handled by increasing the injection rate. Based on the calculations and analyzes that have been done, for the well G1 on field X it will be optimum to operate if frac pack is installed with the type of brady sand 20/40 proppant and dynafrac HT 30 as fracturing fluid, so that half fracture length, Xf 76.8 ft is obtained with fracture width, wf 0.4355 ft and 5 times fold of increase in the production. From this study it can be concluded that the calculation model made can be accepted and used commercially.[/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][/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][/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/10.1063/5.0006814[/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]
