Pipesim-OLI Link
• Concept introduced at the last Simulation Conference
• Pipesim is the industry standard multiphase fluid flow simulator
• Used in inflow, wellbore, flowline and production system modeling
• File-based thermodynamic link between ScaleChem and Pipesim
• ScaleChem provides scaling information which Pipesim uses to model solids deposition
Pipesim-OLI Link
• Pipesim can read thermodynamic and phase behavior and properties from a PVT text file
• A grid of values at each data point (T,P) ranging from Tmin to Tmax, Pmin to Pmax
• 2-dimensional quadratic interpolation between grid points
• ScaleChem provides all this data, including scaling information with formation curves
• Pipesim can then predict the amount, type, tendency of the scale

Callable Corrosion Engine
• Developed for OLGA dynamic simulator
• Calculates corrosion rates given shear stress and pipe operating conditions
• Also has a module to estimate shear stress if not available
• Wide range of metal surfaces supported
• Multiphase flow added in addition to static, single phase and completely agitated conditions
