Abstract:

The liptinitic-rich coal and other organic-rich sediments from the Cau Formation in block 07 Nam Con Son basin is believed to be a major source rock. The coal is dominated by vitrinite, with moderate by bituminite, suberinite, sporinite and resinite and low amounts of inertinite. The rockeval analysis shows that the coals are enriched in hydrogen (hydrogen index up to 410 mg HC/g TOC) and depleted in oxygen (oxygen index up to 10 mg CO2/g TOC). The value of Tmax ranges from 427 to 439 °C, indicating a low level of thermal maturity, the vitrinite reflectance is between 0.44 and 0.79% consistent with the The Tmax
