This section details the drilling wells used for backstripping . LS33 and LW31 were performed by the CNOOC whose detail data can be found in table S1 and S2, respectively.Thelithology of a layer is coded by its sand/clay ratio. For example,the code of pure sandstone is 1 and pure mudstone is 2. The code of 1.8indicates a layer with 20% sandstone and 80% mudstone.
