US Patent 12065901 Expanding and collapsing apparatus having bookend seal cartridges

Systems and methods presented herein include expanding and collapsing apparatus that include a slips cartridge that is bookended by seal elements. The pressure (e.g., whether from uphole and/or from downhole of the downhole tool) pushes at axial points at which the seal elements abut the slips cartridge. In addition, all of the load is transferred to the wellbore casing, and not to an inner mandrel at all. Specifically, the inner mandrel only experiences the setting force in tension. In addition, the elastomer that is being used is not stretched during expansion, but simply moved as it is expanded.
