These basins have been proven to produce oil and gas. The research area is located about 100-150 km east of Salawati Basin and Bintuni Sub-basin. Furthermore, the study area is located in Dawai Village, Yapen Waropen District-Yapen Island, Papua Province, Indonesia in UTM 53-s between 684000-692000E and 9799000-9809000N. This paper explains about stratigraphy, facies, and diagenesis of limestone in Wurui Formation. The stratigraphic, facies, and diagenesis of limestone can be known: the age of limestone is Te-Tf or N7-N17 or Early-Late Miocene. The depositional environment is between inner-middle neritic (0-100 m). The facies of limestone can be distinguised by LBF-red algae Packstone, Planktonic-Foraminifera Packstone, Skeletal-Coral Packstone, and Planktonic-Foraminifera Packstone-wackestone. The diagenesis products of limestone are cementation, micritization, replacement, dissolution, neomorfisme, and dolomitization, and also burial. The diagenesis phases of limestone can be divided by development of marine cement on fossils and matrix, stylolites formation, and fracture filling. The changing indication of deposition environment can be interpreted by cementation environment (micrite to iron oxide cement) from mixed marine to phreatic meteoric water.[/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]Depositional environment,Dolomitization,Fracture filling,Late Miocene,Marine cements,Meteoric waters,Planktonic foraminifera,Study areas[/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/10.3997/2214-4609.201412660[/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]
