SANDNES, NorwayAker BP has contracted Techouse for a FEED extension study for a sulphate removal unit for the Valhall IP platform in the Norwegian North Sea.

The FEED work will be delivered via the Aker BP and Aker Solutions Modification Alliance.

Aker BP aims to increase production and extend the life of Valhall’s wells by reducing the scaling caused by sulfate in seawater injected into the reservoir to maintain pressure and maximize production.

The sulfate reacts with the formation water in the reservoir, causing scaling that can result in clogging, impact reservoir performance, and damage to the well.

Techouse’s solution will reduce sulfate present in the seawater prior to injection into the reservoir, thereby removing the potential for scaling and the attendant formation of hydrogen sulfide.

The company has completed an initial study for the delivery and onshore functional testing for the project: it will undertake more detailed engineering during the FEED study over the remainder of this year.

Its agreement with Aker BP includes an option for engineering, procurement, construction, and onshore functional testing, and full offshore testing at the Valhall field center. The completed system should be ready for offshore installation in summer 2023.
