FIELD: geophysics.
SUBSTANCE: invention relates to combined methods of geophysical investigations in prospecting and exploration of hydrocarbon deposits and can be used for forecasting and evaluation of properties of reservoirs based on results of seismic exploration, electrical prospecting and geophysical survey of wells. Disclosed is a method of predicting saturation of headers, which involves comparing the characteristics of the target interval with the RES and the longitudinal conductivity S, obtained as a result of performing electrical exploration using the side-tracking method, performing normalization of electrical prospecting data according to the side-tracking method to well data. Method also includes multivariate geological modeling, multivariate geoelectric modeling based on the created geological models, determining a set of geological models satisfying initial geoelectric data.
EFFECT: high information value of geophysical data and accuracy of the geological model.
