... of detection. Lower frequencies are used by these tools in the range of 2–64 kHz. In low- to mid-range resistivities, the lower frequencies provide a greater depth of investigation but with lower spatial resolution. At higher resistivities, greater depths of detection can be achieved with the higher-frequency...
