Abstract:
Drilling telemetry systems and methods include a cable antenna a cable antenna in an auxiliary borehole in a subterranean formation arranged to receive electromagnetic signal transmitted from an EM tool in an adjacent wellbore in the subterranean formation. The cable antenna may include a wireline cable having a center core, an insulated electrical cable head in direct electrical communication with the center core, and an uninsulated signal receiver in direct electrical communication with electrical cable head. The uninsulated signal receiver may have an outer surface formed of a conductive material and configured to contact a natural subterranean formation.

Claim (Index 18):
A drilling telemetry system comprising:\n an EM tool sized and configured to be disposed on a drill string and introduced into a wellbore in a subterranean formation, the EM tool comprising a transmitter configured to transmit an electromagnetic signal through the subterranean formation; and a cable antenna sized and configured to be introduced into an adjacent auxiliary borehole in the subterranean formation and to receive the electromagnetic signal transmitted from the EM tool, the cable antenna comprising:\n a wireline cable having a center core, a polymeric insulative layer disposed about the center core, and an outer protective layer disposed about the polymeric insulative layer; \n an electrical cable head having a housing, an electrical conductor in electrical communication with the center core of the wireline cable and extending through the housing, and a cable anchor attached to the outer protective layer and configured to secure the electrical cable head to a distal-most end of the wireline cable, the housing having a distal end having a spring-loaded contact; and \n an uninsulated signal receiver disposed at a distal-most end of the cable antenna and formed of a rigid, conductive material having a diameter of about 2 to about 12 inches, the uninsulated signal receiver having a conductive outer surface exposed to engage against a natural subterranean formation when the cable antenna is disposed in borehole, the uninsulated signal receiver being in direct electrical communication with the spring-loaded contact to provide uninterrupted electrical communication between the conductive outer surface and the electrical conductor of the electrical cable head.
