The model includes the presence of mud cake layer and irreducible water saturation. Here, a linear flow system is considered. The filtration velocity and mud cake thickness model is derived from Darcy law and mass conservation. The invasion depth is obtained from mud filtrate profile in formation. It is found that the filtration velocity in a linear flow system depends on overbalance pressure, formation permeability, mud cake characteristics (porosity, permeability and density), and invasion time. Furthermore, the model is verified using the experimental data from literature. The invasion depth predicted by the present model is in agreement with the experimental results. © 2011 Elsevier B.V.[/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]Damage zones,Darcy law,Experimental data,Filtration velocity,Formation permeability,Irreducible water saturation,Linear flows,Mass conservation,Mud cakes,Mud filtrate,Mud-filtrate invasion,Thickness model,Water-based mud,Water-based muds[/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]Damage zone,Invasion depth of mud filtrate,Water-based mud[/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]Parts of this research are funded by RISET ITB no. 241/K01.7/PL/2009 .
