Abstract:
An apparatus for use in a wellbore is disclosed. The apparatus includes a string for deployment into the wellbore, the string including at least one packer and an expansion tool downhole of the packer. The expansion tool further includes: a release device and a lock device inside a movable housing; wherein the lock device prevents shifting of the release device until the lock device is moved to an unlock position by application of a first force to the lock device. The release device is movable to a release position by application of a second force after the lock device has been moved to the unlock position. The movable housing is capable of moving over the release device after the release device has been moved to the release position to absorb at least one of contraction and expansion of the expansion tool.
