Classification: CPC G  E | IPC G

Claim 15:
16. A system for predicting electromagnetic properties of drilling mud and a formation, the system comprising at least one processor that, when executing program instructions stored in memory, is configured to:
obtain measurements of current injected into a measurement zone adjacent a sensor electrode at multiple frequencies, wherein the measurement zone includes the drilling mud and the formation;
process the measurements of the current at the multiple frequencies to determine complex impedances for the sensor electrode at the multiple frequencies;
generate input data based on the complex impedances for the sensor electrode at the multiple frequencies; and
supply the input data to a system of artificial neural networks (ANNs) that is configured to predict and output electromagnetic properties of the drilling mud and the formation within the measurement zone based on the input data, wherein the system of ANNs employs a cascaded architecture of multiple ANNs and
generate a borehole image over varying azimuth and depth using the electromagnetic properties.
