Scale risk

ScaleChem calculates scale risk profiles from reservoir to water injection / disposal, identifying critical scale risk points to optimize chemical treatment. It auto-generates scale contours for a range of T and P so you can quickly see how the scale risk varies from current conditions. Both MEG and methanol systems are covered.

Facilities modeling

ScaleChem models topside facilities so you can check scale risk here too. Advanced features determine H2S partitioning in the oil, gas and water phases, enabling a check against material and safety limits.

Contour diagram

Temperature / pressure contour diagrams can be automatically generated for tens of thousand of points. The changes in scale potential as well as in any other calculated property can be conveniently visualised and exported as graphs or tables.
