Patent

CA 2254390

A packer is provided which reduces the number of components required in a retrievable packer. The packer is compact in size, and convenient and economical in use. In a described embodiment, the packer includes seal carrying and gripping assemblies mounted on a mandrel. Axial compression of the assemblies causes a seal and grip structures carried on the assemblies to radially outwardly deflect. Each of the assemblies may be integrally formed, thereby further reducing the number of components needed to construct the packer. Each of the assemblies is usable separately on the mandrel to produce apparatus which only grippingly engage or only sealingly engage a tubular member in a well. The packer or similar apparatus is retrieved by releasing the force axially compressing the assemblies.
