“…Fortunately, some methods and technologies, such as a refined fluid inclusion analysis of reservoir rocks (Mclimans, 1987;George et al, 1997;Xiao et al, 1996Xiao et al, , 2002Munz, 2001;Parnell et al, 2001;Liu et al, 2003b;Tao et al, 2003), petroleum generation kinetics, and gas carbon isotopic fractionation kinetic modeling of source rocks (Tissot et al, 1987;Ungger and Pelet, 1987;Pepper and Corvit, 1995;Tang et al, 2000;Xiao et al, 2005Xiao et al, , 2006, and 2D and 3D basin modeling (Ungerer et al, 1990;lnan et al, 1997;Mann et al, 1997;Schneifer and Wolf, 2000;Lutz et al, 2004;Justwan et al, 2006;Lampe et al, 2006), can provide information related to petroleum origin in reservoirs and deeply-buried source rocks. The aim of this paper is to present an approach to tie a deeply-buried source rock to a petroleum reservoir using integrated geological and geochemical techniques through a case study of the W9-2 petroleum pool in the Wenchang A sag of the Pearl River Mouth Basin, South China Sea.…”
