Abstract
One of the probable causes of formation of zones of higher polarizability above oil and gas роо ls may be secondary rock epigenetic sulfidization . Processes of secondary epigenesis and their interrelation with observed anomalous manifestations are considered by the example of North-Guliaev oil and gas deposit (Barents shelf). According to the model of secondary rock epigenetic sulfidization numerical calculations of pyrite concentration were performed using simplified O.F.Putikov’s formula. A correlation between theoretical calculations and results of experimental investigations on North-Guliaev oil and gas deposit indicated agreement between calculated pyrite concentration and observed induced polarization anomaly .
