The studies methodology used includes: (1) Subsurface data collection and data laboratory analysis. (2) Data processing method, starting with identifying the existence of the Lower Baong Formation from the data well log and report. (3) Data analysis method in the form of analysis of patterns produced from data processing. (4) The characteristics of lithology and the potential of shale hydrocarbons quantified in the attributes of geomechanics. The results of the studies: a) The lower Baong Formation can be divided into 5 (five) lithofacies. The characteristics of each lithofacies in each well have different lithological variations and compositions. b) The results of the calculation of the brittleness index (BI), indicating that the lithology of Calc. Siltstone has the highest BI value than lithology of Calc. Shale. c) Based on mineralogical composition, it can be a conclusion that BI values are strongly related to mineralogical composition; indicated by the presence of brittle minerals, and clay minerals. d) Lithology Calc. Siltstone in PPT-3 well (depths of 2187-2125 and 2095-2035 meters) are zones that have potential as a reservoir in shale hydrocarbon systems. e) Correlation of northwest-southeast wells shows sediment deposition thickness in several different wells; this is due to the paleogeography of the basin during the deposition process of the Lower Baong Formation which is estimated to be controlled by the presence of low and height caused by tectonic processes.[/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]Brittleness index,Geomechanics,Lithofacies,Lower Baong Formation,Reservoir,Shale hydrocarbons,Unconventional[/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][/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]
