A Comprehensive Review of Saline Water Correlations and Data: Part II—Thermophysical Properties

This paper reviews the thermophysical properties of saline water correlations and data. The key parameters that influence the properties are considered, such as multi-component composition, high salinity, temperature, and pressure. Since the thermodynamic properties are reviewed in part I of the paper, this part (# II) focuses on the thermophysical properties involving viscosity, surface tension, electrical conductivity, thermal conductivity, osmotic coefficient, activity coefficient, and thermal expansivity. The properties are comprehensive to include all saline water types, i.e., brackish water, seawater, high saline water from basins, lakes, produced water from oil and gas hydraulic fracturing, and so on. The correlations are summarized in tabular forms and assessed based on their accuracy against available experimental data. Besides, guidelines for choosing some correlations are also discussed. Since the thermal conductivity has no multi-component model, a novel and straightforward model is proposed with excellent accuracy.
