Carbonate scaling - literature review and analysis
A survey of the literature on carbonate scaling is presented as it affects geothermal fluid systems. The geothermal brine, as the fluid is called, contains a number of chemical constituents which have leached into it from the reservoir rock. As the hot fluid is withdrawn through wells, a flow of steam, water, or a mixture of steam and water, results. If the well flows at a high enough rate, some brine will flash to steam because of the pressure drop, resulting in the steam/water flow mixture. The chemical composition of the brines is tabulated as the composition of the components in the water system before flashing and the composition of the non-condensible gases after flashing. Total dissolved solids vary from that of ordinary well water to concentrated solutions as high as 40% by weight. Calcium is a major cationic constituent, and biocarbonate an important anionic constituent of the brine. Prevention/treatment techniques, specific site experimental results, and computer models are presented.
