Underwater Wellheads

The first underwater completions were a series of gas wells on the north shore of Lake Erie. Designed to avoid ice damage, trees were installed by suited divers in 20- to 30-ft of water. Shell's RUDAC System used a nested suspension system incorporating casing and tubing hangers, master valves and dual flowline connections for introduction of remote, through-tubing maintenance tools. The concept was first used in West Cameron 192 in 150-ft of water in 1960. Meanwhile on the west coast, Shell used a free-swimming remote controlled robot, called MOBOT, to make up bolts and operate valves. Five wells at Gaviota were completed this way starting in 1962.
