摘要

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 for med from a diallyl ammonium salt and with said scale inhibitor, wherein said polymer formed from a diallyl ammonium salt has a molecular weight of great er than 50,000 (e.g. a molecular weight of 55,000 to 2,000,000).
