1. A method of operations in a borehole comprising:

  • generating a first electric dipole in the borehole that is parallel with an axis of the borehole, and generating a second electric dipole in the borehole that is transverse to the axis of the borehole, the electric dipoles forming an electromagnetic field in a formation that surrounds the borehole;

    using a coil in the borehole at a location spaced axially away from the electric dipoles to sense magnetic flux that is generated by the electromagnetic field; and

    based on the step of sensing magnetic flux, identifying a distance and a direction from the first electric dipole and the second electric dipole to a bed boundary that is in the formation.
