Geochemical characteristics of discovered hydrocarbon in Malay - Tho Chu basin
Abstract
The Malay - Tho Chu basin is located in the South Western continental shelf of Vietnam, including the North East margin of Malay basin and the North of Pattani trough. Results of geochemistry research of source rocks revealed the presence of two source rock sequences (Oligocene and early Miocene). Studies of oil and condensate samples taken from discoveries in the Malay - Tho Chu basin indicated that hydrocarbon discovered in blocks 46 and 46/02 were generated from source rock containing mainly lacustrine organic matter/mixture of lacustrine and terrestrial organic matters which were in the late oil window; hydrocarbon in blocks B and 52/97, which were different in original organic matter, were generated from source rock containing mainly terrestrial organic matter and mixture of terrestrial and lacustrine organic matter, and were highly matured. The possibility that hydrocarbon encountered in the research area were also generated from Oligocene and Miocene source rock in the deeper trough of the Malay basin and migrated from the Pattani trough to the Malay - Tho Chu basin is not excluded.
