Abstract

See full text

A system for anchoring an expandable tubular to a borehole wall comprises a support member having a first end fixed relative to the outside of the tubular and a second end comprising a ramping surface. An anchor member has a first end fixed relative to the outside of the tubular and a second end extending toward the support member, the second end being movable relative to the outside of the tubular. The support member includes a ramp surface that tapers in the direction of the anchor member. Expansion of the portion of the expandable tubular between the first support end and the first anchor end causes the axial device length to shorten, wherein the difference in length is sufficient to cause the second anchor end to move radially outward and engage the borehole wall as a result of engagement with the ramping surface.
