ABSTRACT:
An improved downhole tool apparatus including, but not limited to, packers and bridge plugs which more fully utilize highly stressed non-metallic components, including slips, slip wedges, and packer element retaining shoes than prior tools. The non-metallic packer element retaining shoes of the present invention are preferably made of separate shoe segments initially held in place by at least one retaining band. Such non-metallic packer element shoes do away with troublesome prior art metallic shoes and backups which tended to spin upon each other or about the mandrel while milling or drilling the tool out of a wellbore. Therefore, the subject invention increases the ability to drill or mill downhole tools out of a well bore in less time than it would take with using conventional or non-conventional drilling or milling techniques or equipment.
