Abstract:
A swell packer configured to simultaneously cut and seal a wellbore or slide down and seal a wellbore. The swell packer has a swellable wellbore packer section and a pair of end rings. The end rings couple the substantially 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. At least one diamond cutter insert, polyamide button, or tungsten carbide block can be installed circumferentially and spaced apart symmetrically or near-symmetrically on at least one of the end rings.
