摘要:
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.
摘要:
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.
摘要:
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.
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 foamed 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).

摘要:
The present invention provides compositions of oil-soluble inhibitors suitable for use in inhibiting oil field scale formation. The compositions comprise an acid form of a known scale inhibitor and a tertiary alkyl primary amine. These compositions possess advantages over conventional compositions used for inhibiting oil field scale.
