- •
Oil-type, coal-type and mixed-source gas are recognized in Nanpu offshore area.
- •
Shallow gas is primarily oil-type sourced from Ed3–Es1 source rocks with I–II1 kerogen.
- •
Deep gas is primarily coal-type derived from Es2+3 source rocks with II2–III kerogen.
- •
Primary cracking of kerogen is responsible for most discovered gases.
- •
There is considerable deep gas potential in the Nanpu Sag and the similar basins.
