Abstract: A wellhead assembly that allows electrical power and signals to pass into and out of the well during drilling operations, without removing the valve structure above the wellhead. The invention provides an electromagnetic casing string antenna comprising a plurality of antenna cylinders, one or more control lines connected between the casing string antenna and surface equipment through a passageway in the casing hanger and an antenna module having a sealed induction interface.

Abstract: Methods and apparatus for communicating between surface equipment and downho le equipment. One embodiment of the invention provides a wellhead assembly that allows electrical power and signals to pass into and out of the well during drillin g operations, without removing the valve structure above the wellhead. Another embodiment of the invention provides an electromagnetic casing antenna system for two-way communication with downhole tools. Another embodiment of the invention provides an antenna module for a resistivity sub that effectively controls and seals the primary/secondary interface gap.

Abstract: A casing hanger (920) positioned in a wellhead (910) has an electrical connector (940) which can align with a connection port (912) in the wellhead (910) to allow downhole power and signals communication to be maintained without removing any wellhead valve structure. Alignment wedges can be used to ensure the port (912) and the electrical connector's opening (924) are aligned. The opening (924) can be covered by a debris seal (960) for protection during installation. Also disclosed is an electromagnetic casing string antenna system for two-way communication downhole (see figures 10a-c). Antenna cylinders (1010, figure 10a) can be mounted coaxially on to casing joints (1020, figure 10a) and can be both transmitters and receivers. Also disclosed is an antenna module with sealed induction interface (see figures 13-15). Antenna modules (1320, figure 13) can be mounted in a drill collar (1310, figure 13). The modules are sealed by an epoxy surface (1364, figure 14) which is ground flush to an inside surface (1362, figure 14). The wellhead electrical connector arrangement, casing string antenna system and sealed antenna module can all be used together and are intended to be used in conjunction with a downhole deployment valve (DDV).
