Oilfield scale is the term used to describe deposits of insoluble inorganic minerals such as calcium carbonate, barium sulphate, and metal sulphides. In general, scale deposits occur when waters with different ion contents are mixed although pressure and pH can also affect the deposition of some oilfield scales, e.g., calcium carbonate.
KAT use industry standard static bottle and dynamic flow loop testing for assessing scaling potential and determining the relative efficacies of chemical scale inhibitors.
KAT and AFS, can perform a desktop scaling assessment, supported by confirmatory laboratory testing, to identify the scaling risk potential in a production system (from bottomhole to topsides) using on PVT data, water data and anticipated operating conditions to determine relative saturation ratios and precipitation masses of scale components.
Our dual-operation Sand Pack and Core Flood test rigs can operate up to a maximum of 200°C [392°F] and 8,700psi [600barg] and are used for studying the behaviour of inhibitors in porous media to design and optimise scale inhibitor 'squeeze' treatments. They can also be used to assess both water and gas control technologies. KAT’s innovative temperature, pressure and flow control technology provides maximum experimental flexibility and test method customisation.
