Abstract: The present device and technique relates to measuring geological formation permeability, such as by injection/withdrawal of conductivity-permeability doped fluid and measuring the magnetic permeability and/or conductivity of the surrounding formation. Before, during and/or after injection or withdrawal, pluralities of electromagnetic measurements of the radial distribution of magnetic permeability and/or conductivity of the surrounding formation may be made. The rate of change of the radial distribution of magnetic permeability and/or conductivity of the formation is generally directly proportional to the permeability of the surrounding formation. In implementations, magnetic permeability and electrical conductivity can be measured independently in time domain or frequency domain, such that the magnetic permeability mapping is not disturbed by other confounding electromagnetic parameters.
