Conductor Casing

Component that provides structural support for the well, wellhead and completion equipment, and often used for hole stability for initial drilling operations

• Note: 1 to entry: This casing string is not designed for pressure containment, but upon completion of the well it might have a casing head; therefore, it can be capable of containing low annulus pressures. For subsea and hybrid wells, the low-pressure subsea wellhead is normally installed on this casing string.
