Transient electromagnetics [TDEM]

The methods of transient processes TEM or TDEM belongs to a group of methods of electromagnetic (EM) active diagnosis of geo-electrical center. Measurements are based on the induction of the electromagnetic field into the earth using an inductive loop or galvanic source (LoTEM) The induced alternating electric field is accompanied by alternated, recorded by the inductive loop receiver, magnetic field on which basis the conductivity distribution of geological medium can be calculate.
