摘要：<p>The present invention relates to methods and apparatus for expanding tubulars in a wellbore. In one aspect of the invention, an expansion tool (102) with hydraulically actuated, radially expandable members (116) is disposed on a string of coil tubing. In another aspect of the invention the apparatus is utilized to expand a tubular lining a lateral wellbore into contact with a window of a larger tubular lining a central wellbore.</p>
