Abstract: An integrated system comprising a desalination plant comprising a reverse osmosis (RO) array configured to produce an RO permeate blending stream, a blending system comprising a flow line for a fines stabilizing additive blending stream and configured to blend the RO permeate blending stream with the fines stabilizing additive blending stream to produce a blended low salinity water stream having a salinity of less than or equal to 5,000, 4,000, 3,000, 2,000, 1,000, 500, 400, or 300 ppm and a molar ratio of divalent cations to monovalent cations of greater than about 0.2, 0.3, or 0.4, a control unit configured to control operation of the blending system, and an injection system for one or more injection wells, wherein the one or more injection wells penetrate an oil-bearing layer of a reservoir. A method is also provided.
