Scaling formation
WebScale deposition leads to severe formation damage problems, great permeability reduction, pressure and production losses, and direct financial losses by the failure of some downhole equipment. Scale deposition can be defined as the aggregation of different materials within unwanted parts/areas in the oil/gas production system. WebScales are formed out of salts. These salts come inside the boiler through water in form of soluble solids and are precipitated when the concentration level increases because of …
