Veolia, through its subsidiary VWS Westgarth, has been awarded a multi-million dollar contract by Aibel Singapore on behalf of Woodside Petroleum Ltd for the supply of a customised water flood water treatment system on the Ngujima-Yin floating production storage and offloading (FPSO) facility that will operate in Woodside's Greater Enfield Area Development fields, offshore northwest Australia. This is the first award to Veolia from Aibel Singapore and Woodside, and also the first use of sulfate removal in Australia.
The FPSO is a 332 m double hulled tanker built in 2000 and converted into an offshore production facility to produce oil from the Vincent oilfield. Once separated from gas and water, crude oil extracted from the reservoir is exported from the FPSO onto trading tankers.
The award is for the design, equipment, procurement, supply and construction of a single lift integrated process module, incorporating: coarse filtration, ultrafiltration (UF), pre-treatment, sulfate removal membrane process (SRP), vacuum deaeration, dual fuel turbine dirven water injection pump, electrical switchgear and transformers, and plant control room. The system water injection capacity is 12 720 m3/d (80 000 bwpd), with a turndown capacity to 8745 m3/d (55 000 bwpd).
The heart of the system is the specialised SRP membrane process that is designed to remove sulphates and other divalent hardness ions from injection water used in enhanced recovery water flood operations. The removal of these ions reduces the tendency of barium sulfate and strontium sulfate scale to form in the reservoir and flow lines, plus prevent well sourcing by controlling reducing bacteria.

The EIA reports that US distillate consumption so far this year is lower than usual because of warm winter weather, reduced manufacturing activity, and continued substitution of biofuels in place of petroleum distillate on the US West Coast (PADD 5).
