The present invention provides a method for increasing the retention of a scale inhibitor within a hydrocarbon producing system (e.g. a subterranean formation), said method comprising contacting said system with a polymer formed from a diallyl ammonium salt and with said scale inhibitor, wherein said polymer formed from a diallyl ammonium salt has a molecular weight of greater than 50,000 (e.g. a molecular weight of 55,000 to 2,000,000).
La présente invention concerne un procédé destiné à augmenter la rétention d'un anti-incrustant dans un système produisant un hydrocarbure (par exemple une formation souterraine). Ledit procédé consiste à mettre ledit système en contact avec un polymère formé à partir d'un sel de diallylammonium et avec ledit anti-incrustant, ledit polymère formé à partir d'un sel de diallylammonium présentant une masse moléculaire supérieure à 50 000 (par exemple une masse moléculaire de 55 000 à 2 000 000).
