Abstract
A technique facilitates temporary locking of a mechanical packer to prevent inadvertent actuation of the mechanical packer. The mechanical packer may be set via manipulation of a setting mandrel which works in cooperation with a releasable locking mechanism. The releasable locking mechanism may be initially locked against the setting mandrel and held in place via a piston, e.g. an annular piston, received in a piston chamber, e.g. an annular chamber surrounding the setting mandrel. The piston may be selectively shifted via pressure applied in the piston chamber so as to release the releasable locking mechanism, thus enabling actuation of the mechanical packer.
