Abstract
Electrical energy is induced into an earth formation by a transmitter in apparatus, adapted to be passed through a borehole traversing the earth formation. Clock pulses are also provided in the apparatus. At least two receivers provide signals corresponding to received electrical energy from the earth formation. A gating circuit provides groups of clock pulses in accordance with the signals from the receivers so that the number of clock pulses in each group corresponds to the dielectric constant of the earth formation.
