Telemetrically Operable Packers

A down-hole well control tool activated in response to a telemetry signal, the down-hole well control tool comprising:

• a mandrel defining a longitudinal axis, the mandrel having fasteners thereon for interconnecting the mandrel within a work string;
• a setting piston longitudinally movable over a portion of the mandrel;
• a first electric motor longitudinally anchored to the mandrel and operable to generate a first longitudinal force between the mandrel and the setting piston to move the setting piston longitudinally with respect to the mandrel;
• a communication unit coupled to the mandrel for receiving a telemetry signal;
• a controller coupled to the communication unit and the first electric motor, the controller operable to control the first electric motor in response to the telemetry signal;
• and
• a local power source coupled to the mandrel for energizing at least one of the electric motor, the communication unit and the controller.

A method of setting a packer in a wellbore, the method comprising:

• (a) interconnecting a mandrel into a work string wherein the mandrel has coupled thereto, a communication unit, a controller, an actuator, a setting piston and a sealing element;
• (b) running the work string into a wellbore to dispose the mandrel at a desired location within the wellbore;
• (c) sending a SET telemetry signal from a surface location to the communication unit coupled to the mandrel;
• and
• (d) executing, with the controller and in response to the SET telemetry signal, a predetermined sequence of instructions to cause the actuator to generate a force between the mandrel and the setting piston to thereby longitudinally move the setting piston to compress the sealing element.
