  • Collapse resistant expandables for use in wellbore environments
    Patent number: 7191842
    Abstract: A technique utilizes blocking members to resist contraction of expandables in wellbore environments. The technique comprises an expandable having a wall with a plurality of expandable cells. A plurality of blocking members cooperate with at least some of the cells to resist contraction of the expandable device once transitioned to a desired expanded state.
    Type: Grant
    Filed: March 12, 2003
    Date of Patent: March 20, 2007
    Assignee: Schlumberger Technology Corporation
    Inventors: Matthew R. Hackworth, Craig D. Johnson, Laurent N. Alteirac, Kevin W. Hayes, Don Eubank, Joel McClurkin

  • Technique for expanding tubular structures
    Patent number: 6688397
    Abstract: A system for expanding tubular structures. The system comprises a mandrel that is moved through the center of a tubular structure to increase the diameter of the tubular structure via deformation. The system utilizes an expansion device having a mandrel with multiple segments moved between a contracted state and an expanded state. In one embodiment, the mandrel segments are spring biased to permit a degree of independent movement of each mandrel segment with respect to the other mandrel segments.
