Abstract

Apparatus and method for drilling and completing subsea wells using a wellhead mounted on a pedestal conductor supported above a conductor pipe string by a buoyant member. The conductor string supports a plurality of casings which are cemented over their entire lengths. A single small-diameter casing is suspended from the wellhead and extends over the length of the pedestal conductor.
