Abstract
A liner hanger running tool () and method are provided for positioning a liner in a well bore. A tool mandrel () is supported from a running string, and a housing () surrounds the tool mandrel. A flow annulus between the mandrel and the housing allows fluid to pass upward through the running tool to a position above the liner. A hydraulic release mechanism () is activated by fluid pressure within the mandrel to axially move a piston () positioned radially outward of the mandrel to release the running tool from the liner.
