Abstract: A method of attaching a tubular to an existing tubular in a well without reducing the inside diameter of the well is described. A shoe is attached to the lower end of the existing lowermost casing or tubular, generally prior to the casing being cemented or otherwise secured in the wellbore. The shoe has a diameter larger than the inside diameter of the casing or tubular to which it is attached. Subsequently, a liner is run in until its top end is in the enlarged diameter region of the shoe. A hanger can be optionally used. The liner is expanded into the enlarged diameter so that the net result is that the inside diameter in the wellbore is not reduced by the addition of the liner.

Abstract: An inflatable packing tool is provided for use in a subterranean wellbore. The inflatable packing tool is coupled to a wellbore conduit with a central bore which directs pressurized fluid into the wellbore. The inflatable packing tool includes a central tubular body for directing fluid in the wellbore. Upper and lower stationary collar members are secured to the central tubular body for coupling the central tubular body to the wellbore conduit. An annular inflatable packing element surrounds the central tubular body, and includes a flexible fluid-tight sleeve covered by a plurality of overlapping an axially extending reinforcing ribs. A slidable sleeve assembly is coupled to one end of the annular inflatable packing element.
