ABSTRACT:
A method of drilling and completing an underwater well entails installing conductor casing from a floating vessel into a seabed; drilling a bore through the conductor casing to a defined depth in the seabed; and installing surface casing through the conductor casing. A high pressure wellhead and mudline suspension system engages the surface casing and are disposed on the first end. The lower stress joint is connected to a lower saver sub that connects to the casing riser's lower end. The casing riser on an upper end is connected to an upper saver sub that engages a upper stress joint. The method ends by connecting the upper stress joint to a surface wellhead in fluid communication with a surface BOP; and connecting the surface BOP and the surface wellhead to a tensioning system on the floating vessel; and using a telescoping joint.
