<p>In a method of completing one or a plurality of grouped underwater oil wells, each well head to be connected is temporarily placed in a gaseous medium at atmospheric pressure during connection to effect this, prior to the installation of the well head, a structure is lowered vertically on to the sea bed where the gathering is to be carried out, the structure including an enclosure at atmospheric pressure and housing a manifold, and as many compartments, capable of communicating with the enclosure, receiving a production head and being rendered watertight, as there are well heads to be installed, each compartment being temporarily rendered watertight and filled with gas at atmospheric pressure during connection of the production head, previously placed in the compartment, to the manifold in the enclosure.</p> |
