  • METHOD OF INCREASING SCALE INHIBITOR RETENTION
    Publication number: 20170002258
    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.
