  • Hydraulic set permanent packer with isolation of hydraulic actuator and built in redundancy
    Patent number: 7383891
    Abstract: A packer includes one or more anchors for securing the packer in a wellbore and a pair of seal elements that form a fluid seal. The packer assembly is hydraulically set and, thus, it can be located at any desired position within the wellbore. The packer assembly is secured within the wellbore by a staged setting process through use of shear pins that have increasingly stepped shear values. Redundancy in packer sealing is provided by the use of two seal elements to establish fluid sealing. The design of the packer assembly also provides hydraulic isolation of the actuating portions of the packer assembly upon setting.
    Type: Grant

  • Composite landing collar for cementing operation
    Patent number: 6457517
    Abstract: A composite landing collar is disclosed which is preferably adhesive bonded to the liner string using a high temperature epoxy. The spacing during bonding is maintained within dimensional limits using spacers. The body features a bi-directional material, with an appropriate ratio in the warp and fills directions, for about a quarter of the wall thickness. A unidirectional material with the fibers axially aligned aids in reduction of thermal stresses in the thick wall during curing, as well as reducing shear stress concentration along the adhesive bonding interface.
