When this implementation shows a good promise for the plan of reservoir management, the engineers involved should be able to estimate the drainage area of the horizontal well. This is of importance in optimizing well spacing for the development. This paper presents a method to estimate the drainage area of a producing horizontal well. The method was developed by combining an equation of production decline introduced by Shirman (1998) with an equation of material balance. The advantages of the method presented here over the existing ones available in the literature are simple and no requirement of ultimate recovery data. Field data of four producing horizontal wells were used to evaluate the proposed method. Having the production performance and the rock and fluids properties data, calculation was performed to determine the drainage area of each well under the study. The validation was done by (1) comparing our results with that of a previous study and (2) calculating the productivity index (PI) using a horizontal well inflow equation and then compared with that measured in the field. The comparisons show a very good agreement for all the cases considered, revealing that the method is successfully applied. In addition, the paper also discusses the strategy of orienting a horizontal wellbore to maximize the benefit of horizontal well application.[/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]Productive index (PI),Reservoir management[/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/10.2118/64436-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]
