A packer element is concentrically received about the mandrel. An annular piston is concentrically received about the mandrel and has an annular differential pressure area defined thereon and communicated with the mandrel bore through the power port. The annular piston and packer element are operably associated so that the packer element is set by sliding motion of the piston in response to increased fluid pressure in the mandrel bore. Either a compression set packer element or an inflatable packer element may be utilized.
