The Relationship among Geodynamics, Heat Flow, Deep Structure, and the Oil and Gas Potential of Yamal

The amount of hydrocarbon deposits per unit area of Yamal Peninsula is more than 100 times as much as the global average. The hydrocarbon deposits are generally situated in areas with high current geodynamic activity. According to the data of seismic tomography, in the Yamal area, the mantle structure is abnormal. The southern part of the Kara Sea, the Yamal Peninsula, and the western part of the Gydan Peninsula are involved into the large positive anomaly of the heat flow density, the epicenter of which occurs in the vicinity of the Rusanovskoye deposit. Almost all hydrocarbon deposits of Yamal are situated on the flanks of the West Siberian rift system and, simultaneously, in the gradient zones of the heat flow density.
