Seabox™ subsea water treatment module

Seabox™ subsea water treatment system is an excellent tool optimizing water injection into the reservoir. It provides the flexibility to achieve improved reservoir sweep and the required pressure support, for increased oil recovery. Installed subsea, decoupled from topside facility, it disinfects raw seawater and settles out particles. The Seabox has a standard treatment capacity of 40,000 bwpd.

The Seabox can operate in water depths down to 3,000 meters, feeding treated water either to a subsea injection pump and/or as part of a SWIT™ technology configuration or to topside injection pump and/or processing equipment. Ensuring full flexibility for waterflooding, providing an increased recovery potential. It reduces energy and chemical consumption, and retrofit costs.

SWIT™ subsea water treatment technology

The SWIT™ subsea water treatment technology, includes the Seabox™, ultrafiltration and membrane technology to tailor raw seawater to reservoir requirements – particle-free, low salinity or low sulfate water. Giving the industry subsea alternatives for effective increased and enhanced oil recovery.

The SWIT™ technology provides superior quality of injection water, removing sulfate and reducing salinity, enabling enhanced oil recovery. The system reduces the need for maintenance, without compromising performance. The Seabox™ module is the main differentiating part of the technology, securing long term maintenance free operation of membranes, enabling unmanned operations, reduced power requirements and carbon footprint.
