Abstract
A well completion apparatus disposed in a wellbore having first and second tubings and a tool disposed in the second tubing. An inductive coupler has a male coil located in the first tubing and is configured to receive an input signal. A female coil in the inductive coupler is attached to the first tubing and is electrically connected to the tool for inductively coupling to the male coil. An output signal is induced in the female in response to the input signal received in the male coil, and the output signal is provided to activate the tool in response to the input signal.
