SUBSIS — the world's first subsea separation and injection system

Abstract SUBSIS is a subsea separation and injection system from ABB, developed to increase recovery and improve the economics of offshore oil and gas fields while also having a positive impact on the environment. The key task of SUBSIS is to separate the bulk water from the wellstream and to treat it for either discharge into the sea or re-injection into the reservoir. Modularized and self-contained, it will set new standards for the economic and environmentally friendly production of oil and gas.
