Electromagnetic signal repeater and method for use of same

摘要

A downhole electromagnetic signal repeater apparatus (76) for communicating information between surface equipment and downhole equipment. The apparatus comprises: a receiver (120) receiving an electromagnetic input signal and transforming the electromagnetic input signal to an electrical signal; an electronics package (122) electrically connected to the receiver (120) for amplifying the electrical signal; and a transmitter (124) electrically connected to the electronics package (122) for transforming the electrical signal into an electromagnetic output signal that is radiated into the earth.
