Abstract: A method for increasing the retention of a scale inhibitor within a hydrocarbon producing system is provided. The method includes, the steps of: (i) pre-flushing the system with a liquid; (ii) treating the system with a scale inhibitor; and (iii) over-flushing the system with a composition comprising an ionic polymer and a liquid carrier. The concentration of the ionic polymer in the composition is 5 to 50% wt.

Abstract: 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).
Abstract: Provided is a method for inhibiting scale formation within a hydrocarbon producing system, said method comprising contacting said system with a polymer formed from a diallyl ammonium salt, a monomer comprising one carboxylate group and a monomer comprising at least two carboxylate groups or an anhydride group. Also provided are hydrocarbon well treatment compositions and polymers for use in connection with the provided methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
