Abstract

Abstract A method of completing a well by installing in the well a flow conductor, performing various operations such as cementing the flow conductor in the well bore, drilling out excess cement from the flow conductor, perforating the casing at desired locations, and the like, installing a liner in the flow conductor of smaller internal diameter than the internal diameter of the flow conductor to provide an internal seal surface and oppositely facing stop shoulders in the flow conductor, setting a packer in the liner, and then installing an inner production flow conductor in the well and securing it to the packer. A setting tool for simultaneously locating a liner and a packer in a flow conductor, expanding the liner into sealing and anchored engagement in the flow conductor and then setting the packer in the liner.
