Abstract
More than ten gas pools in the shallow water region of the Pearl River Mouth (PRM) Basin and the Qiongdongnan (QDN)<br>Basin, the Offshore South China Sea have been discovered since 1983. Gases produced from QDN Basin are characterized by<br>high contents of benzene and toluene and relatively heavy delta13C2 values (-25- -27 permil), and the associated condensates<br>by high abundance of bicadinanes and oleanane, which indicate a good correlation with the coal-bearing sequence of the<br>Oligocene Yacheng Formation in the Basin.
