Abstract
An inflatable packer is shown which includes a tubular mandrel and an inflatable, elastomeric sleeve secured to the mandrel at opposing ends thereof. A friction enhancing media is applied to the exterior surface of the mandrel by wrapping a grit laden tape about the mandrel exterior surface. The particulate material contained within the outer surface of the tape increases the coefficient of friction between the mandrel and the sleeve to retain the sleeve in its original position while the device is being run into position within the well bore.
