OPEN HOLE ANCHOR

摘要

The present invention relates to a method and apparatus for anchoring a n expandable tubular within a wellbore prior to expanding the length of the expandable tubular into contact with the wellbore. An expandable system comprises the expandable tubular and a deployment toot, wherein the deployme nt tool exerts radial force against the expandable tubular to expand at least a portion of the expandable tubular into contact with the wellbore to anchor the expandab le tubular prior to the expansion process. A method for anchoring an expandable tubular within a wellbore prior to the expansion process is also provided, wherein radial force expands the expandable tubular into contact with the wellbore t o initially anchor the expandable tubular. A method for altering the shape of the anchor is also provided.
