• Subsea Water Injection

    NOV signed its first contract for the Seabox™ subsea water treatment system. The contract was signed with a major operator who will deploy the system at an offshore installation in the third quarter of 2018 for an extended test during the 2018/2019 winter season. The Seabox system enables water treatment to be done directly at the seabed and water to be pumped straight into the injection well. This will allow the operator to optimize waterflooding and improve oil recovery. Two successful pilot projects, backed by the Norwegian Research Council and several major oil companies, have demonstrated that the Seabox system reduces water treatment costs compared to other types of systems. 

    Water injection is the most common way to increase oil production, but traditionally, this has required expensive and bulky topside equipment. With the Seabox™ subsea water treatment unit and SWIT™ Technology, the water treatment is done directly at the seabed and the treated water is pumped straight into the injection well. The SWIT Technology provides the right quality water for water injection where it is needed, when it is needed. This fully flexible approach allows operators to optimize water flooding with the right quality water at any time and location to improve recovery.

    Seabox subsea water treatment unit and SWIT Technology is a subsea technology, developed during the last 10 years with support and sponsorship from major oil companies. The technology enables treatment of raw seawater directly on the seabed to the desired quality for injection into oil wells for pressure support, sweep and increased oil recovery. The development started in 2003 and embarked on a series of Joint Industry Projects (JIP) backed by the Norwegian Research Council and major oil companies. Through these projects, the Seabox unit and SWIT Technology have been developed and are now ready for real applications.
    As a part of National Oilwell Varco’s Subsea Production System, we are uniquely placed to work directly with oil companies, subsea contractors, engineering houses, and industry suppliers to provide the highest level of added value to the overall project. This philosophy ensures that the optimum constellation in any given project is always available to the client.
