We investigated the electromagnetic filed of a current loop in a conducting ferromagnetic cylinder for applications of casing monitoring in petroleum wells. We tested different transmitter-receiver configurations for excitation and recording of TEM and stationary magnetic fields, studied the responses to changes in electromagnetic and geometrical parameters of casing strings, and determined the intervals of highest sensitivity.
