Claim:
1. A method for fracture identification and characterization, comprising: 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 being tilted with respect to an axis of the borehole; generating a time-varying electromagnetic (EM) signal with the magnetic dipole transmitter; measuring a response of the formation to the time-varying EM signal using the magnetic dipole receiver, the response comprising at least two depths of the formation and at least two azimuthal orientations of the formation with respect to the axis of the borehole; generating a first image of the formation based, at least in part, on the response; and determining at least one fracture characteristic based, at least on part, on the first image and a synthetic fracture image, wherein determining at least one fracture characteristic based, at least on part, on the first image and the synthetic fracture image comprises determining at least one of a presence, shape, size, average resistivity value, and edge location of the fracture.
