The organic-rich shale of the Bagong Formation contains mixed organic matters, with the TOC of 0.65%-3.10% and the R_o value of 1.17%-1.59%, meeting the standard of moderate source rock. Fourth, four shallow wells (depth of 50-250 m) showed oil flower respectively in the organic shales at 50-90 m in the lower part of the Bagong Formation and 30-75 m in the middle part of the Quse Formation. The crude oil contains a high content of saturated hydrocarbon. Analysis and testing of outcrop and shallow well samples confirm the presence of marine shale oil in the Bagong Formation and the Quse Formation. Good shale oil intervals in the Bagong Formation are observed in Layers 18-20 in the lower part of the section, where the shales with (S₀+S₁)˃1 mg/g are 206.7 m thick, with the maximum and average (S₀+S₁) of 1.92 mg/g and 1.81 mg/g, respectively. Good shale oil intervals in the Quse Formation are found in Layers 4-8 in the lower part of the section, where the shales with (S₀+S₁)˃1 mg/g are 58.8 m thick, with the maximum and average (S₀+S₁) of 6.46 mg/g and 2.23 mg/g, respectively.]]>
