TAILIEUCHUNG - Petroleum system modeling in cenozoic sediments, Block 05-1a, Nam Con Son Basin

The results of assessments for source rock, oil sampling analysis is used to determine the relationship between in–situ oil or oil migrated from other places. The workflow of basin modeling is assigned to get output (migration pathways, volume of accumulation), as well as data calibration. Main source rocks include H150, H125 shales and H150 coal with Total organic carbon (TOC)~1 and 47 respectively. | Tạp chí Phát triển Khoa học và Công nghệ, tập 20, số K4-2017 91 Petroleum system modeling in cenozoic sediments, Block 05-1a, Nam Con Son Basin Xuan Van Tran, Huy Nhu Tran, Chuc Dinh Nguyen, Tuan Nguyen, Ngoc Ba Thai Kha Xuan Nguyen, Thanh Quoc Truong, Trung Hoang Quang Phi, Minh Bao Luong Abstract—Based on the update of exploration data the oil and gas potential within block 05-1 are studied through define the source rocks, Hydrocarbon (HC) generation, expulsion and migration, focusing on source rock Oligocene /Early Miocene and Middle Miocene; Define the accumulation of hydrocarbon in Lower Miocene targets; The results of assessments for source rock, oil sampling analysis is used to determine the relationship between in–situ oil or oil migrated from other places. The workflow of basin modeling is assigned to get output (migration pathways, volume of accumulation), as well as data calibration. Main source rocks include H150, H125 shales and H150 coal with Total organic carbon (TOC)~1 and 47 respectively. These source rocks are medium to good potential. At the present time, most of the source rocks are in oil window, while the deep parts is in gas window. Oil started to be generated in Early Miocene, and started to be expulsed in Late Miocene. Gas started to be generated in Quaternary, about to be expulsed. The oil migrated mainly from the troughs at the West and minorly from the East and South to Dai Hung High. Gas started to migrate from West to East and South West to North East at the Western part. However, at the Eastern part, gas migrated from the opposite direction. The results of sensitive analyses show more oil in max source rock case, therefore, a 3D model development is Manuscript Received on August 7th, 2017. Manuscript Revised December 25th, 2017.
