Abstract:
A method for performing dual mode imaging of a borehole determines a reference point in a geological formation in response to a resistivity measurement of the formation. The reference point is associated with a feature, such as a fracture, in the formation. A tilt angle of the feature is determined, with respect to the reference point, in response to the received electromagnetic signals from the formation. For example a time-of-flight, ranging operation may be performed or an attenuation and phase change of the received signals may be determined to image the feature.
