1. A fracturing characterization method comprising:

  • positioning an electromagnetic resistivity tool in a borehole proximate to a formation;

    obtaining a borehole wall image log;

    obtaining three-dimensional (3D) formation resistivity measurements collected, as a function of different depths, azimuths, and radial distances from the borehole, by the tool;

    combining information from the borehole wall image log with the 3D resistivity measurements to determine at least one fracture parameter; and

    halting fracturing of the formation, by reducing the flow rate of fracturing fluid by a processor, when the at least one fracture parameter satisfies a set of criteria.
