METHOD OF GEOPHYSICAL PROSPECTING BY ELECTRIC MEANS Russian patent published in 2005 - IPC

FIELD: geophysics.

SUBSTANCE: method comprises generating low-frequency electromagnetic field with the use of ungrounded loop at the day earth surface, measuring Cartesian components of magnetic induction from parallel profiles at given levels, measuring real and imaginary parts of the Cartesian components of the magnetic induction with respect to the phase of the vertical component of the magnetic induction in the epicenter of the ground loop, determining deviations of measured components from the normal values for a homogeneous medium, and determining sections of increased electric conductivity from the sign and magnitude of these values.

EFFECT: enhanced accuracy and efficiency of measuring.
