Abstract
A method for characterizing one or more properties of a geological formation including brine, the method including inputting at least one first property of the geological formation into an equation of state (EOS) model, the EOS model accounting for a high temperature effect on the brine; solving the EOS model to determine at least one second property of the geological formation; and outputting the at least one second property to a display device.

A method for characterizing one or more properties of a geological formation including brine, the method comprising:
- (a) inputting at least one first property of the geological formation into an equation of state (EOS) model, the EOS model accounting for a high temperature effect on the brine;
- (b) solving the EOS model to determine at least one second property of the geological formation;
- and
- (c) outputting the at least one second property to a display device.
A method for characterizing one or more properties of a geological formation including an aqueous phase, the method comprising:
- (a) measuring at least one first property of the geological formation using a downhole tool;
- (b) inputting the at least one first property into an equation of state (EOS) model, the EOS model accounting for a high temperature effect on the brine;
- and
- (c) solving the EOS model to determine at least one second property of the geological formation.
