Abstract
Abstract A gravel pack well tool for use in a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then the well tool having a auger-liner assembly is lowered and rotated into the preset gravel. The liner assembly is comprised of a fluid-permeable linear surrounded by a torque sleeve which transmits torque from a workstring to a nose sub at the leading edge of the liner assembly. The nose sub has a fish-tail bit thereon to assist the downward movement of the liner assembly into the preset gravel and has passages therein for fluid flow therethrough in the event the assembly becomes stuck in the gravel during installation.
