Rock physics modeling is applied in this study as it is an accurate, precise and practical method for the case of carbonate reservoirs. It is examined to determine the effect of carbonate reservoir geometry on the seismic wave velocity in carbonate field using fast DEM (Differential Effective Medium) model. We integrate measured logs and petrophysics data from gas-saturated carbonate reservoir. The results show that majority of pore geometry in the research area are interparticle pores and micro-cracks pores. The pore geometry interprets the effects of seismic wave velocity of carbonate reservoir in the study area, stiff pores or the increasing of α values will make the seismic wave velocity to increase rapidly and crack pores or the decreasing of α values will make the seismic wave velocity slower. Generally, we have worked in the common geological condition of carbonate reservoir rocks. In terms of aspect ratio value, our reservoirs controlled by overburden geological process. This indicated that fracturing is closely related to overburden and differential compaction, thus increasing the connection between separate vugs and enhancing permeability dramatically.[/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]Carbonate reservoir,Chemical materials,Differential compaction,Differential effective mediums,Geological conditions,Geological process,Rock physics model,Seismic wave velocity[/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/10.1088/1755-1315/311/1/012031[/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]
