Crysalt, a private scale predictor for oilfield brines

Field notes

The page describes a thermodynamic workflow rather than a black-box correlation: brine conditions feed speciation, activity, and mineral-saturation calculations across a single state or a pressure-temperature path. Its displayed example uses 60 °C and 50 bar, predicting barite and calcite supersaturation with concentrations, saturation ratios, and saturation indices. The listed coverage includes 10 scale minerals, more than 21 aqueous species, and conditions above 200 bar. The deployment model is a local MCP server or REST API.
