The paper shows possibilities of 3D seismic exploration for solving structural problems, tectonic and tectonophysical modeling
of East Siberian deposits, prospecting and exploration of oil and gas deposits. Possibilities of improvement of prospecting and
exploration methods of HC deposits in West Siberia are based on new ideas on regional manifestation of latest shift tectonics.
For deposits of West Siberia, complicated by structures of horizontal shift (SHS) new type of near-shift oil has been substantiated
(model of layer-vein saturation deposits) and relations of bore-hole productivity and deformation conditions of compression-extension
within the limits of dynamic effects of basement displacements are demonstrated. The model of "compression wedge" and its
improvement into "wedge-in-wedge" made possible to substantiate structural features of stretching and permeability of rocks for
designing wells with high output at the deposits complicated by the structures of horizontal displacements.
Key words: structures of horizontal shift, deformational conditions of compression-extension, productivity of wells.
