- The chemistry of high-HCO/sub 3/ resources is emphasized because they present special complications about data interpretation, development of vapor, and potential for scale deposition. Solubility of CO/sub 2/ and its exsolution from liquids is treated according to the unique context presented by geothermal resources. Contrasts between this approach and the treatment of CO/sub 2/ solubility in physical chemistry and other geochemical contexts are presented. Dimensional units for solubility coefficients different from those of physical chemists are presented to favor engineering application. The effects of CO/sub 2/ on wellbore flow, initiation of flashing, and depth of the 2-phase zone are described and illustrated with examples. To aid the understanding of fluid behavior and the interplay with the design process, specially constructed charts - chemical maps - are presented, examples given for their use, and directions given for their construction.
