摘要： Apparatus and method for securing and sealing a tubular portion to another tubular to provide a liner hanger in oil and gas wells. At the top of the liner string, a sleeve is arranged on the liner to create a chamber therebetween. A port provides fluid access through the liner to the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to the cemented casing. A lower fluid pressure is required to morph the sleeve than if the liner itself was to be morphed. Embodiments are provided for securing and sealing arrangements to increase the metal to metal seal and the load capability between the liner string and casing.
