Deeply buried (3.5–4.5 km) fan deltaic and braided deltaic sandstones of the Eocene Shahejie Formation are important hydrocarbon reservoirs in the Raoyang Sag of the Bohai Bay Basin (North China). An integrated approach incorporating petrophysics, thin﹕ection petrography, scanning electron ...
Deeply buried (3.5–4.5 km) fan deltaic and braided deltaic sandstones of the Eocene Shahejie Formation are important hydrocarbon reservoirs in the Raoyang Sag of the Bohai Bay Basin (North China). An integrated approach incorporating petrophysics, thin‐section petrography, scanning electron ...
Raoyang SagBaxian SagThree potential source rock intervals were evaluated based on the results of Rock-Eval pyrolysis on nearly 700 rock samples and the origin of the twenty-two oil-fields was studied by the biomarker analysis on 62 source rock samples and 93 oil samples in the Raoyang Sag ...
Raoyang SagBaxian SagThis paper discusses migration styles and primary controls of petroleum migration pathways in heterogeneous carrier beds in the Damintun Depression, Bohai Bay Basin. There are two types of crude oils in the Damintun Depression: a high wax oil (wax hydrocarbon content between ...
