GEOPHYSICAL ELECTRIC PROSPECTING METHOD Russian patent published in 2005 - IPC

Abstract RU 2248016 C1

FIELD: geophysical electric prospecting.

SUBSTANCE: method can be used for ac geophysical electric prospecting which current is induced in ground by inductive method; method can be used for searching and prospecting objects as in non-conducting and conducting media. Low-frequency electromagnet field is induced by current running in non-grounded loop onto day surface of Earth. Phase shifts of components of magnetic induction are measured at preset height for parallel profiles relatively vertical component of magnetic induction along profile crossing epicenter of loop and being perpendicular to parallel profiles. Availability of abnormal conducting objects in Earth is determined from structure in phase shifts at the area.

EFFECT: improved precision of measurement; improved efficiency of aerial prospecting.
