ABSTRACT:
A pad mounted resistivity imaging device includes at least one transmitter and two or more arrays of receivers. Analysis of the received signals is done using either amplitude and phase differences between the arrays of receivers, or by analyzing amplitude and phase differences between the transmitters and the receivers. With operating frequencies in excess of 10 MHz, high resolution images of boreholes are obtained.
