It is primarily run in a single trip, it is retrievable and designed to be compatible with the PARAGON suite of wireless tools for use in single DST’s, multi-zone DST’s and production wells.
The KRYSALIS high-integrity single-trip packer is set by opening a port to a hydrostatic setting chamber and allowing well pressure to act on a piston. This pressure provides the setting force and movement of the packer components during transition, also releasing the seal stem assembly, allowing the packer to be spaced out.
The packer can be set by bursting a rupture disc or opening the setting port using a wireless telemetry activation command.
The packer is retrieved by applying tension to the seal stem, shearing out the tool, collapsing the slips and creating an area for the packing element to relax whilst opening a flow bypass to prevent swabbing.
