USFilter was recently selected to supply a water injection system, with sulphate removal, by Total E&P for the Dalia field, offshore Angola.
The company was chosen by the joint venture, TSS Dalia, comprised of Technip as leader, Saipem and Stolt Offshore, in a consortium with Samsung HI and Daewoo SME.
The system, engineered by USFilter Zimpro Systems includes multi-media filtration, vacuum deaeration and sulphate removal membrane skids. The complex system will supply 265,000 barrels per day of low sulphate seawater for injection to prevent barium scale formation in the reservoirs and production piping.
The award is the second water injection system with a sulphate removal package supplied by USFilter for Total's operations in Angola. The first system for the Girassol field is successfully operating and capable of 400,000 barrels per day of low sulphate injection water.
