Method for improving the accuracy of mud angle measurements in borehole imagers

A method and system for estimating a mud angle. A method may include disposing a downhole tool into a borehole, energizing a button array, transmitting a current from the electrode into a formation, recording the current from the formation with a return electrode to obtain a plurality of measurements, identifying at least one low resistivity zone from the plurality of measurements to produce a measurement set, inverting the measurement set to find a mud angle vector, removing the mud angle vector from the measurement set to obtain a corrected measurement, and obtaining an electrical image using the corrected measurement. A system may include a downhole tool, a conveyance, and an information handling system. The downhole tool may further include at least one electrode and at least one return electrode.
