Abstract
A liner hanger () is provided for supporting a liner in a well. An expandable tubular hanger () is positioned within the well and a running tool with a tool mandrel () passes fluid through the running tool. An actuator () forcibly moves the tubular expander to an expanded position. Release of the running tool from the liner may be accomplished with a retainer () and downward movement of the mandrel, with fluid pressure acting on a hydraulic piston () coupled with rotation of the mandrel, or by safety joint () along the tubular mandrel.
