Abstract
A downhole induction resistivity assembly comprises a mandrel. Disposed around the mandrel are coils of wire disposed circumferentially around magnetic field concentrators. The coils of wire and the magnetic field concentrators are disposed on an outer diameter of the mandrel. A magnetic field deflector, of magnetic permeability greater than the mandrel, is disposed intermediate the coils and the mandrel.
