Abstract
A downhole activation system within a tubular. The system includes an axially movable mover. A first magnet attached to the mover. The first magnet axially movable with the mover. A second magnet separated from the first magnet. The second magnet magnetically repulsed by the first magnet. A biasing device urging the second magnet towards the first magnet; wherein movement of the first magnet via the mover towards the second magnet moves the second magnet in a direction against the biasing device. Also included is a method of activating an activatable member in a downhole tubular.

A downhole activation system within a tubular, the system comprising:
- an axially movable mover;
- a first magnet attached to the mover, the first magnet axially movable with the mover;
- a second magnet separated from the first magnet, the second magnet magnetically repulsed by the first magnet;
- and,
- a biasing device urging the second magnet towards the first magnet;
- wherein movement of the first magnet via the mover towards the second magnet moves the second magnet in a direction against the biasing device.
A method of activating an activatable member in a downhole tubular, the method comprising:
- moving a mover, having a first magnet attached on an end thereof, in a first direction;
- and
- magnetically repulsing a second magnet, biased in a second direction opposite the first direction, in the first direction via the first magnet;
- wherein the activatable member is coupled to the second magnet and activated by movement of the second magnet.
