More than 20% of the world's discovered gas reserves are considered to be of biogenic origin. The significant late Quaternary shallow biogenic gas accumulations of the eastern coast of China are found in the Hangzhou Bay area at depths from several decameters to more than a hundred meters. Since 1991, six shallow gas fields and one gas pool have been discovered in the Hangzhou Bay region. Their discovery shows that this kind of shallow biogenic gas can be explored and exploited.Based on
