Abstract

Den foreliggende oppfinnelse tilveiebringer en fremgangsmåte til å øke tilbakeholdelsen av en skallavsetningsinhibitor i et hydrokarbonproduserende system (f.eks. en underjordisk formasjon), hvor nevnte fremgangsmåte omfatter å bringe nevnte system i kontakt med en polymer dannet fra et diallylammoniumsalt og med nevnte skallavsetningsinhibitor, hvori nevnte polymer dannet fra et diallylammoniumsalt har en molekylvekt større enn 50000 (f.eks. en molekylvekt mellom 55000 og 2000000).
