A joint venture of the sister companies VWS Westgarth and VWS Brazil of Veolia Water Solutions & Technologies has been awarded a contract by MODEC for a project development offshore Brazil. The award is for the supply of a sea water treatment package as a completed single-lift module, comprising coarse strainers, media filtration pre-treatment, vacuum deaeration and sulphate removal process (SRP) systems with a product capacity of 24,000m³/day (150,972bwpd).

The contract will be project managed and engineered in VWS Westgarth’s offices in East Kilbride, in the outskirts of Glasgow, where the company’s numbers have grown to more than 150 oil and gas industry dedicated staff. Sister company VWS Brazil will provide local engineering support, project management, local procurement and supervision of the module fabrication from their Rio de Janeiro office base.

The SRP is designed to remove sulphates and other divalent hardness ions from injection water to enhance oil recovery using Dow / Filmtec SR90-440i membranes. The removal of these ions reduces the tendency of barium sulphate and strontium sulphate scale to form in the reservoir and prevent well souring by controlling sulphate-reducing bacteria.

This is the second SRP project to be awarded to VWS Westgarth by MODEC, and can be attributed in some manner to the good working relationship the companies have with the execution of the first MODEC contract for a project to be located offshore Angola.

VWS Westgarth is an upstream water treatment specialist and a member of the VWS oil and gas division of Veolia Water Solutions & Technologies.
