  • Compact retrievable well packer
    Patent number: 6123148
    Abstract: 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.

  • Gravel pack assembly
    Patent number: 4570714
    Abstract: A well apparatus connected to a pipe string extending down into a cased borehole for treating a formation comprising a packer assembly for sealing with the casing assembly and an integral crossover/release assembly attached to the packer assembly for supporting and releasing a gravel screen assembly before or after treating the formation without rotating the pipe string. The crossover/release assembly includes crossover ports providing a downward flow path for the treating fluid, annular veins providing an upward flow path for the returns, and a reciprocating piston reciprocating upon effecting hydraulic pressure on the piston for releasing the gravel screen assembly.
