Petroleum Geochemistry and Exploration in the Afro-Asian Region: Proceedings of the 6th AAAPG International Conference, Beijing, China, 12-14 October 2004 : CRC Press : 9780415440837 : 0415440831 : 11 Oct 2007 : Petroleum Geochemistry and Exploration in the Afro-Asian Region includes 29 papers presented at the 6th International Conference on Petroleum Geochemistry and Exploration in the Afro-Asian Region. Petroleum geochemistry has played a crucial role in determining effective source rocks, classifying petroleum systems and delineating the geneses of conventional and unconventional oils and gases. By reference to petroleum geochemistry, the dynamic process of petroleum accumulations can be traced, which helps determining the prospecting target areas and reducing the exploration risk. Petroleum exploration is also enhanced by basin modeling and petroleum system classification, through the application of geochemical data.  There has been significant progress in petroleum exploration du
