Abstract

Authors developed the complex way for searching of hydrocarbons deposits on the Russian arctic seas shelf by seismic, electric prospecting and magnetometric methods, including telluric methods. Article describes the offer on inclusion of additional methods in a complex of marine seismic exploration and marine electric prospecting that will allow increasing effectiveness and reliability of searches of fields of hydrocarbons on the shelf. As a base of integration was used the principles of classical (standard) methods of oil and gas search on shelf to get the structural model of geological medium and detect the reservoirs. Article includes the recommendation for complex interpretation improvement of observed geophysical data. Description of features of complex fieldworks implementation is presented. New methods of data processing which allow detecting the weak anomalies and study the thin structure of magnetic field to find out the anomalies by type of Donavan are showed. The effectiveness of described offer how to improve the reliability of shelf hydrocarbons deposits search with complex of geophysical methods increase multiply in compare with using just seismic and electric prospecting bottom complex. This reliability achieves because of possibility more widely use the features of substantial composition of rock-reservoirs at the interpretation of complex data as a result of longitudinal conductivity studying.
