Compositions and methods for the use in scale inhibitor squeeze treatments are provided. In some embodiments the present disclosure provides a method including introducing a pre-flush fluid into at least a portion of a subterranean formation, the pre-flush fluid including a choline chloride chemical additive; and introducing a treatment fluid including a scale inhibitor into the portion of the subterranean formation after at least a portion of the pre-flush fluid has been introduced into the portion of the subterranean formation.

Enhanced scale inhibitor squeeze treatment using a chemical additive

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.

Method of increasing scale inhibitor retention

A method for increasing the retention of a scale inhibitor within a hydrocarbon producing system by (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.

A method for delivering a scale treatment agent to a hydrocarbon producing system. The method includes the steps of contacting the system with a foam comprising the scale treatment agent, and shutting the scale treatment agent in the system for at least 0.5 hour.

Well treatment

This invention provides a method for inhibiting scale formation within a hydrocarbon producing system, said method comprising contacting said system with a copolymer formed from a diallyl ammonium salt and at least one other monomer.

Scale inhibiting well treatment

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.

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).
