Zusammenfassung: | A method of removing built up aluminosilicate scale in a conduit of a geothermal plant reinjection well in which a fluid comprising mineralized water is flowing. The method comprises alternately treating the fluid in the conduit with an acid composition and a caustic composition via a lance, wherein treating is carried out without stopping the fluid flow in the conduit. The caustic composition may comprise a chelator and a surfactant dependent on analysis of the scale. |
