Abstract: A method of seismo electromagnetic detecting of hydrocarbon deposits has the steps of simultaneously initiating an electromagnetic field and a seismic wave in investigated geological region so that an electromagnetic signal originates by vibrating of hydrocarbon deposit surface excited by the electromagnetic field and travels from the surface, recording the electromagnetic signal together with transient electromagnetic process in the region, and making a conclusion about a hydrocarbon deposit based on the recorded electromagnetic sign together with the transient electromagnetic process.

Abstract: Methods are disclosed employing seismic waves having infrasonic frequencies in the range of about 0.1-20 Hz for generating electromagnetic waves of similar infrasonic frequency in hydrocarbon bearing subterranean formations located at depths up to about 5000 meters, said electromagnetic waves having sufficient voltage amplitudes for detection at the earth's surface. Also disclosed are seismic sources capable of generating infrasonic seismic waves of sufficient amplitude for generating electromagnetic waves in hydrocarbon bearing formations at depths up to 5000 meters, said electromagnetic waves having voltage amplitudes sufficient for detection at the earth's surface.
