FRACTURE DETECTION AND CHARACTERIZATION USING RESISTIVITY IMAGES

摘要

An example method for fracture identification and characterization may include positioning a magnetic dipole transmitter and a magnetic dipole receiver within a borehole in a subterranean formation. At least one of the magnetic dipole transmitter and the magnetic dipole receiver may be tiled with respect to an axis of the borehole. The magnetic dipole transmitter may generate a time-varying electromagnetic (EM) signal. The magnetic dipole receiver may measure a response of the formation to the time-varying EM signal; the response may include at least two depths of a formation and at least two azimuthal orientations of the formation with respect to the axis of the borehole. An image of the formation may be generated based, at least in part, on the response, and at least one fracture characteristic may be determined based, at least in part, on the first image and a synthetic fracture image.
