Oil and gas potential of the West Kamchatka coast and its relation to the structural and tectonic structure of the Sea of Okhotsk region based on geophysical data
This article describes the peculiarities of the deep structure of sedimentary depressions of the West Kamchatka coast and the adjacent offshore areas of the Okhotsk Sea shelf, manifested in the observed potential fields, as well as in their transformations. To reveal geophysical regularities reflect...

This article describes the peculiarities of the deep structure of sedimentary depressions of the West Kamchatka coast and the adjacent offshore areas of the Okhotsk Sea shelf, manifested in the observed potential fields, as well as in their transformations. To reveal geophysical regularities reflecting the structure of the deepest part of the crystalline basement within the analyzed objects, a pseudo gravity field calculated on the basis of analytical approximation was used. The regional and local components of the decomposition of the observed potential fields, calculated by two-dimensional adaptive energy filtering and presumably associated with different-depth structural-tectonic objects, were analyzed. On the basis of comparison of the investigated Pustoretsky depression with the «reference» Kolpakovskaya depression, which includes known gas-condensate fields (West Kamchatka oil-and-gas bearing region), conclusions about the similarity of their formation conditions and subsequent evolution were made. A regional geophysical model of the Pustoretsky depression has been compiled, which makes it possible to reasonably assume its formation in the zone of Cenozoic subduction processes caused by the interaction of lithospheric plates. |
