| Abstract | A field on the application of an organic additive, carboxylic acid copolymer, was conducted in an actual geothermal system to evaluate its effectivenessin preventing silica deposition brine containing ultra high silica concentration (1000-1300ppm). A low concentrationof polymer was applied for about five months, and treatment efficiency based on silica concentrations in various sampling points ranged fiom 64-98 %. Treatment efficiency improved over time. Massive silica scaling in the fluid collection and disposal system was minimized, while nominal scaling at the separator vessel and gel deposition occurred at the pipeline |
