Injection of treated seawater into oil reservoirs is, by far, the most common method for achieving IOR (Increased Oil Recovery): - It typically doubles recovery, typically from 20-25% to 40 -50% - A reliable treatment plant tha t gives good quality water is essential for reservoir protection and can increase these recovery figures even further. During 15 months of subsea testing, Seabox's subsea water intake and treatment (SWIT) system was seen to produce superior water quality compared to a typical topside treatment plant in areas that are important for IOR. SWIT enables a new level of flexibility in reservoir drainage strategies and IOR potential is significantly increased by enabling injection of as much treated seawater as r equired, where / when required, without typical host platform restrictions. Recent work on detailed design & interface issues means the system is ?ready to go? and is being considered by several operators for field applications. The use of membranes to pr oduce low sulphate / low salinity water increases the possibility for even further increases in recoverable reserves. Several major oil companies are on record as saying that production of low salinity water may enhance recovery by a further 10%. Statoil plans to use this technology on the Heidrun field and prof. Austad at the University of Stavanger won the 2011 IOR award for his 'designer water' concept - especially suited for use in chalk reservoirs such as Ekofisk. Using the good quality SWIT treated water, Seabox are now planning tests that confirm they can significantly increase the lifetime of membranes used for production of low sulphate/ salinity water. If successful, this could be a significant step towards increased IOR and membrane treatment on the seabed.
