Journal ArticleDOI
Chemical geothermometers and mixing models for geothermal systems
TL;DR: The most widely used quantitative chemical geothermometers are silica, Na/K, and Na-K-Ca as mentioned in this paper, which can provide information about present probable minimum subsurface temperatures.
Journal ArticleDOI
Theoretical prediction of the thermodynamic behavior of aqueous electrolytes at high pressures and temperatures:II. Debye-Huckel parameters for activity coefficients and relative partial molal properties
TL;DR: In this article, the Debye-Hiickel parameters are sensitive quasi-asymptotic functions of pressure and temperature, which may be monotonic or exhibit extrema, depending on the property.
Journal ArticleDOI
Thermodynamics and kinetics for mixed calcium carbonate and calcium sulfate precipitation
Tzyy Haur Chong,R Sheikholeslami +1 more
TL;DR: In this article, the effects of CaSO4 on CaCO3 precipitation were studied in the batch tests at 60, 70 and 80°C in mixtures having calcium carbonate as the dominant salt and at a given total initial calcium concentration of 0.03 M with sulfate concentration ranging from 0 to 0.01 M.
Journal ArticleDOI
Kinetics and thermodynamics of calcium carbonate and calcium sulfate at salinities up to 1.5 M
R. Sheikholeslami,H.W.K. Ong +1 more
TL;DR: In this article, the effect of salinity on kinetics and thermodynamics of precipitaion for CaCO3 and CaSO4 when they exist in isolation as well as together was examined.
Journal ArticleDOI
Sulfate removal technologies for oil fields seawater injection operations
TL;DR: In this article, an innovative membrane distillation and liquid-phase precipitation (LPP) technology was developed for the selective removal of sulfate from seawater before injection, which can be injected safely in oil fields for flooding and pressure support.
