These scales are sulfates such as calcium sulphate (anhy- drite, Chapter Outline. Scale inhibitors are mainly used for the anti-scaling. During the nineteenth century, natural materials such as tannins, starch and lignin were used to prevent scale deposits in the interior of water boilers (Gill 1996). These chemicals are also known as threshold inhibitors since they are able to control scale threat at a very low concentration of a few milligrams per liter or lower [5], [41], [44]. most common oilfield scales are listed in Table 1, along with the primary variables that affect their solubility [2]. 6). 12 From Waste to Insight: Generating High Resolution It is well documented that oilfield scales are inorganic deposits formed due to the precipitation of solids resulting from brines that are present in the reservoir and production system.
