Thermolytic dynamics and prediction of natural gas generation from marine source rocks in the deepwater area of Qiongdongnan Basin, China

Abstract

Present study is to quantify individual natural gas generation in the deepwater area of the Qiongdongnan Basin based on the basin modeling from the shallow-water, and to evaluate kinetic parameters and geological extrapolations using an optimization procedure. Kinetic model presented reproduces the detailed features of shale pyrolysis and coal processing. The idea of blending these two approaches is not new, but until now the most sophisticated attempts reproduced only the gross features of kerogen cracking. It will help to forecast preferable prospect area, and to accelerate the prospecting of natural gas in the deepwater area of the Qiongdongnan Basin.
