Patent ID: 7204305

Claim:
A system for installing a liner conduit in a borehole, the system comprising a packer assembly adapted for insertion in the borehole with a running tool, the packer assembly comprising: (a) a packer sealing device, the packer sealing device being adapted to be actuatable from a collapsed configuration for positioning the packer assembly in the borehole to an expanded configuration for sealing the packer assembly in the borehole by the application of a packer sealing actuating pressure to an interior of the running tool; (b) a packer latch device adapted to releasably engage a complementary running tool latch device on the running tool in order to releasably connect the packer assembly with the running tool, the packer latch device being adapted to disengage from the running tool latch device in order to disconnect the packer assembly from the running tool by the application of a latch actuating pressure to the interior of the running tool; and (c) a packer bypass device for bypassing a fluid from an exterior of the packer assembly to an interior of the packer assembly, the packer bypass device being adapted to be actuatable from an open position to a closed position by the application of a packer bypass actuating pressure to an interior of the running tool.
