Downhole tubular inspection combining partial saturation and remote field eddy currents

A system may include an electromagnetic (EM) logging tool. The EM logging tool may include a mandrel, at least one low-frequency transmitter coil disposed on the mandrel, at least one-low frequency receiver coil disposed on the mandrel, and at least one-high frequency sensor configured to measure on...
