Abstract

An isolation liner incorporating a drill pipe and a swell packer, the swell packer configured to simultaneously cut and seals a wellbore, or slide down and seal a wellbore having a swellable section and a pair of end rings. The end rings couple the cylindrical body to the swellable wellbore packer section. Each end ring forms an annular abutment surface that cooperates with the swellable member to inhibit axial movement of the swellable member on the substantially cylindrical body. On each end ring, at least one diamond cutter insert, polyamide button, and/or tungsten carbide blocks is installed circumferentially and spaced apart symmetrically or near-symmetrically on the end ring.
