Field cases are an excellent source of information on real-life scale issues. In this first session on field experience, we will hear about the development of a comprehensive scale management strategy using a ‘scale risk factor’ to optimize chemical consumption on the Norwegian Valhall asset. A case study from the Southern North Sea will show how fresh water injection to prevent halite scale deposition resulted in complete blockage of the well with barium sulphate. Finally, a field case from deep water Gulf of Mexico will introduce a new treatment fluid to overcome challenges when fracturing wells using seawater.
