Evaluating efficiency and stability of calcite scaling inhibitors at high pressure and high temperature in laboratory scale

Abstract Reduction or prevention of scaling is commonly achieved by injecting scaling inhibitors into the geothermal circuit. Inhibitor-efficiency tests can be carried out in static or dynamic experiment set-ups allowing measurements at high pressures and high temperatures (HPHT). For these measurem...
