Abstract
A magnetic susceptibility and conductivity tool () which incorporates a transmitter coil () energized with a time-varying current from a transmitter coil drive (). The transmitter coil drive receives a clock signal and induces a data signal () including a primary mutual coupling signal and a formation coupling signal. A receiver coil () outputs a receiver coil voltage induced by the data signal. A transmitter coil current sense circuit () receives current from the transmitter coil and outputs a digital coil current voltage signal. A synthetic null circuit () receives the digital current voltage signal and multiplies the digital current voltage signal with a predetermined constant () for amplitude of a base primary mutual coupling signal and shifts phase with a predetermined phase offset () to output a synthetic null signal ().
