Abstract

Syreholdige behandlingsvæsker som omfatter en syreholdigvæske og minst en esterinneholdende, kvaternær ammoniumforbindelse (esterkvat) samt fremgangsmåte for bruk av samme. En utførelsesform av oppfinnelsen angår en fremgangsmåte for å hindre korrosjon på metalliske flater under en underjordisk behandlingsoperasjon, omfattende bruk av en syreholdig behandlingsvæske ifølge oppfinnelsen. En annen utførelsesform av oppfinnelsen angår å hindre slamdannelse under en underjordisk behandlingsoperasjon ved bruk av slik væske. En ytterligere utførelsesform angår å hindre dannelse av emulsjoner eller å redusere mengden av dannet emulsjon under en underjordisk behandlingsoperasjon.
