Currently the northeastern territories, which host significant potential hydrocarbon resources, take on particular importance among the regions of Russia promising for oil and gas. The western part of the Yenisei-Khatanga regional trough and the zone of its junction with the West-Siberian Plate are among the promising regions with proven commercial oil and gas occurrence. The paper considers the main Callovian-Turonian reservoirs in the western Yenisei-Khatanga regional trough, provides sandstone thickness maps and qualitative assessment of petroleum potential.

On the basis of complex interpretation of the time seismic cuts given GIS on 42 wells and petrophysic to materials, the digital geological model of distribution of sandy collectors of jursko-cretaceous adjournment is constructed. Perspective zones for formation of deposits of hydrocarbons are allocated, laws of distribution of breeds-collectors are shown. Source

Seismic stratigraphy, as method of geological interpretation seismic sections is wide practical useful in order of Oil & Gas exploration. Negative side of this method is strong dependence between wave image of geological object and frequency features of seismic data. Those features are related with type and area condition of source, processing and etc. Another problem is consist in interference of refracted signals on the seismic traces. This problem can solved by the additional processing (inversion) of stacked section. One of the ways is creating the impulse section from the ordinary section by Dynamic Compression (DC). DC can divide interference wave packets for the detail analyzes local structures. DC is improving time definition of the seismic record and quality of litho-stratigraphic interpretation. The paper describes the algorithms and presents experimental results of DC on different models. Source

Induction and polarization fields are additive in the near-zone of the transmitter and its dependence from dimension and/or configuration of transmitter-receiver system is different. This allow to separate induction and polarization fields using the results of transient soundings with different transmitter-receiver system. The examples of induction and polarization fields separation in polymetallic ores exploration are introduced. Source

The results of near-surface seismic experiments with the high-frequency source on piezoelectric elements are presented in this paper. It has demonstrated that the first brakes of refracted waves can be correlated in offsets about 300 meters. The results show high resolution of the obtained data and that the method is better in wave generation that the traditional methods of wave generation. Source
