The Magnus oilfield lies approximately 160 km NE of the Shetland Islands in the UK sector of North Sea. Areal sweep and pressure support is achieved via sea water injection into the reservoir. Due to the layered nature of the reservoir, formation water and sea water are often co-produced and are commingled in the production wellbore. This has often resulted in downhole deposition of barium sulphate scale and an appreciable reduction in well productivity. A combination of scale inhibitor chemistry and its dcployment into the reservoir using novel diverting agents has significantly reduced the problems and are described in detail in this paper.
