Abstract
The paper presents a new method of focusing electrical logging (FL) which implies a nontraditional layout of transmitter and receiver electrodes. This configuration provides compensation of the background signal from formation and highlights anomaly signals. We suggest a 1D numerical model to process the synthetic differential signal from a FL ring loop and analyze apparent resistivity curves obtained from a 1D two-layer
