A completion and producing system is described for a well drilled in an area covered by deep water. It includes a large buoyant storage tank positioned in the water below wave action. The tank has a slight upward buoyancy. It is held in position by a long, preferably flexible, conduit connected to the well head in the floor of the body of water. A smaller production conduit is positioned inside the large outer flexible conduit and is connected to the string of producing tubing in the well. A narrow cylindrical neck extends from a large tank to above the surface of the water where it supports a work deck and helicopter deck. A gas-oil separator and other treating equipment is carried within the large buoyant tank. Means are provided to transport oil from the storage tank to a transport vessel.
