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.

Collapse resistant expandables for use in wellbore environments

A technique for deploying expandables is provided. The technique comprises actuating an expansion tool such that the expansion tool imparts an outwardly directed radial force on an expandable tubular. More specifically, the expansion tool imparts radial expansion forces against an interior surface of the tubular thereby allowing the tubular to be deployed in a wellbore environment.

Technique for deploying expandables

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.
