Abstract:
An apparatus for use downhole is disclosed. The apparatus includes a downhole device and an actuation device that includes: a housing including an annular chamber configured to house a first fluid therein and a piston in the annular chamber that divides the annular chamber into a first section and a second section. The piston is to a biasing member. A control unit enables movement of the first fluid from the first section to the second section to supply a second fluid under pressure to the tool to move the tool into an active position and from the second section to the first section to stop the supply of the second fluid to the tool to cause the tool to move into an inactive position.
