All rights reserved.SLS field is one amongst the biggest in North West Java block and has been operated, exploitated since more than 40 years ago. Upper Cibulakan Formation which deposited back in Early to Middle Miocene, has been contributing large number of hydrocarbon production. Upper Cibulakan was formed in shallow marine depositional environment and consists of interbedded sandstone and claystone with carbonate units in some area. Professionals, especially geologists and geophysicists should be able to tackle the challenges encountered in order to perform effective interpretation on existing assets. In this case, the writer found out that Accoustic Impedance interpretation is not appropriate enough to describe the reservoir. In addition, there are several limitations in data availability such as seismic data in post-stack time migration that hold us to perform further interpretation such as AVO or Vp/Vs and also the absence of several logs in the well data. Based on said reasons, the writer applied multiattributes analysis on the available data to predict S-wave log, and generate Mu-Rho volume analysis to support the analysis obtained from accoustic impedance analysis. Merging the two interpretations, the writer concluded a recommendation of prospect area with porosity >20% and Mu-Rho >7,5.[/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]attribute,Depositional environment,Hydrocarbon production,Mu-Rhp,Multi-attribute analysis,Multi-attributes,Reservoir characterization,seismic[/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]accoustic impedance,attribute,Mu-Rhp,multiattributes,seismic[/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/10.1088/1755-1315/318/1/012042[/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]
