Abstract
The possibility of application of electrical prospecting method SGN (sounding by field growing in the near-field zone) in combination with CDP seismic prospecting for sedimentary section investigations and hydrocarbon deposits prospecting is considered. The physical basis of the method application for hydrocarbon prospecting is the effect of higher resistance of seams, saturated by hydrocarbons. The effect is reflected in the curve of electromagnetic field growth ε(t). The procedures of field works, processing and interpretation of electrical prospecting data are presented.
