Low sulfate seawater mitigates barite scale

Abstract

Low-sulfate seawater (LSSW) technology provides operational and economic benefits for desulfating seawater to control barium sulfate (BaSO{sub 4}) and strontium sulfate (SrSO{sub 4}) scale. This concluding article in a three part series describes, from a scale control perspective, the membrane technology deployed in the North Sea Brae fields.
