Abstract
A wellbore tool system for use within a wellbore includes a stage packer shoe, having a lower body extending from a first end to a second end; an upper body attached to the lower body at the second end; and circulation ports extending through a thickness of the upper body; a metal cup having a predetermined diameter as determined by a diameter of the wellbore; the metal cup secured around a periphery of the lower body of the stage packer shoe such that the metal cup extends away from the periphery; the metal cup is to engage with the wellbore enough to have differential pressure holding capability between the stage packer shoe and the wellbore; and the differential pressure of the metal cup is dependent on a strength of the cup and the wellbore with which the metal cup is engaged.
