| Abstract | A new correlation to estimate the solubility of carbon dioxide in water for the temperature interval of geothermal interest (fi-om 25?C to 350?C) is proposed. This equation was derived from a comprehensive statistical analysis applied to an up-dated thermodynamic database containing experimental solubility data reported in the literature. In addition, a usefbl equation is presented to quantify the propagated error generated through the use of the new polynomial correlation. These equations will be implemented into a new geothermal wellbore simulator (under construction) for modelling the vertical-ascend of two-phase flow in geothermal wells. |
