A new scale prediction software
ScaleSim™ is an advanced scale prediction software from Scale Consult, developed through 25 years of research and industry feedback. Evolving from Dr. Baard Kaasa's PhD scale code - formerly known as MultiScale - it has been refined into a robust thermodynamic simulation tool for complex oil-gas-water systems. ScaleSim predicts scale potential, scale mass, salt solubility, pH, gas-water equilibria, and water solubility in hydrocarbons across a wide range of pressures, temperatures, and fluid compositions.
ScaleSim integrates the Pitzer activity coefficient model with an Equation-of-State (EoS) PVT model to calculate thermodynamic properties and non-ideal behaviour in oil-gas-water multiphase systems. The framework incorporates classical thermodynamic models, chemical equilibrium calculations for acid/base reactions and salt solubility, and rigorous mass balances. This comprehensive approach enables precise predictions of full three-phase equilibrium and salt precipitation.
ScaleSim has been extensively validated against experimental data spanning diverse compositions of oil-gas-water systems. ScaleSim is applicable for conditions up to 3000 bar and 300°C.
ScaleSim includes all common ions and components typically found in oil and gas production systems and cover all types of hydrocarbon systems from dry gas to heavy oils and all types of water from condensed water to saturated brines. The PVT model includes all hydrocarbon components normally reported in PVT analyses and provides full characterisation of the C10+ fraction. The model accounts for all scale types typically encountered in oil and gas operations, including carbonates, sulfates, sulfides, chlorides, and others.
ScaleSim delivers exceptional computational speed, calculating complex multiphase profiles of up to 32 points in less than a second. Results are instantly available for plotting or export to Excel, enabling rapid and confident scale risk assessment.

ScaleSimPro - The process simulator
ScaleSimPro allows you to simulate scale potentials across complete topside systems—from separators and heaters to pumps and scrubbers. Using Excel as its interface, you can easily adjust conditions, flow rates, well contributions, lift gas rates, and all other parameters in the process to evaluate their effects on scaling, pH, and composition.
Built on the same advanced thermodynamic model as ScaleSim™, ScaleSimPro provides accurate and powerful simulations of scale risk, pH, and phase compositions through a full topside process. With its powerful scenario module, ScaleSimPro allows the user to model how scale potential, pH and all other parameters will vary using the expected production profile.

MEG Module
Mono Ethylene Glycol (MEG) is extensively employed as a thermodynamic hydrate inhibitor in subsea production systems, preventing gas hydrate nucleation and growth as produced fluids cool and water condenses. The presence of MEG significantly alters the chemistry and thermodynamics of the aqueous phase - affecting gas and salt solubility, CO₂ dissociation, and pH.
The MEG module in ScaleSim accurately models these effects using data-driven thermodynamic models developed at NTNU. With this module, users can simulate how MEG, along with additives like pH stabilisers, impacts scale risk and fluid behaviour in flowlines, separators and MEG process. When combined with ScaleSimPro, it is possible to model a full MEG loop including a MEG regeneration or reclamation process.

H2S Scavenger Module
H₂S scavengers are commonly used to remove H₂S from gas streams or well fluids — but their high pH can significantly increase the scale risk for carbonate and sulfide minerals such as CaCO₃, FeCO₃, and FeS once introduced into the process system. The H₂S Scavenger Module in ScaleSim allows users to simulate how injecting H2S scavengers such as triazine, MBO, or EDDM removes H2S and how it affects pH and scale risk in a topside process.
With this module, users can model the chemical impact of H₂S removal and understand how scavenger efficiency influences system chemistry. The simulation calculates changes in pH and scaling potential based on user-defined reaction efficiency.
