1. A method of providing a cemented open hole intelligent completion in a well containing an open hole having a perimeter in which one or more laterals are embedded, the method comprising:
deploying a first string section in a portion of the open hole containing the one or more laterals, the first section having intelligent completion components including inflow control valves, temperature and pressure gauges and control lines that communicate with and are operable from a surface station;
deploying a second string section coupled to and positioned above the first string section and above all of the one or more laterals, the second string section including a liner and a liner hanger assembly controllable to fix the liner with respect to the open hole, the second string section further including a disk assembly, a casing joint, a pup joint, a liner cementing valve and a setting packer expanded up to the perimeter of the open hole; and
delivering cement downhole, the cement setting in a cemented section comprising an annulus between the second string and the perimeter of the open hole, the cemented section being seated on the setting packer,
wherein the cemented section is positioned above all of the one or more laterals so as to block fluids that emanate from the one or more laterals from production while not interfering with communication between the surface and the intelligent components of the first string.
