ABSTRACT:
A submergible, underwater well completion habitat and a method of employing the same in the completion of wells at extended depths. The well completion habitat may be attached to an underwater well platform and maintained at a pressure of sufficient value to expel water from the work chamber and also to maintain it substantially water free so that one or more saturated divers may work within the chamber to complete the well. This abstract of the invention is neither intended to define the scope of the invention, which, of course, is measured by the claims, nor is it intended to limit the invention in any way.
