Integrated 3D Seismo-Gravity/Magnetic Modeling in Study a Deep Structure of the Ob-Taz Region

摘要

The considered territory covers an area of the Ob, Taz bays and adjacent onshore of the Yamal and Gydan peninsulas. The Yamal, Gydan and Ob-Taz shallows is oil-and gas-bearing region in the northern part of the large West-Siberian Province. A deep geological structure of the Ob-Taz shallows has not been studied enough. The purpose of this article is to illustrate new results about the deep geological structures of the Ob-Taz Region from recent seismic survey and an integrated interpretation of seismic and gravity/ magnetic data on the basis of 3D modeling. New information about the deep structure is important for a common valuation of hydrocarbon potential of the Ob-Taz Region.
