Abstract: A desalination system includes a feed pump having an inlet side and an outlet side. In addition, the system includes a first RO stage having an inlet, RO permeate outlet and RO concentrate outlet. Further, the system includes a second RO stage having an inlet, RO permeate outlet and RO concentrate outlet and an NF stage having an inlet, NF permeate outlet and an NF concentrate outlet. The system also includes a set of conduits adapted to connect: (a) the outlet side of the feed pump to the inlet of the first RO stage; (b) the concentrate outlet of the first RO stage to (i) the inlet of the second RO stage and to the inlet of the NF stage; and (c) the permeate outlet of the first RO stage, the permeate outlet of the second RO stage and the permeate outlet of the NF stage either directly or indirectly to a low salinity water injection line.

Abstract: A method of operating a filtration unit of a filtration system includes
feeding, during filtration, feed water containing suspended particulate material to an inside of each of a plurality of hollow fibres through a first inlet and a second inlet of each hollow fibre while simultaneously removing a filtrate from an outside of each of the hollow fibres through an outlet of a filtration elements. In addition, the method includes feeding,
during back-washing, back-wash water to the outside of the hollow fibres through the outlet of the filtration element. Further the method includes discharging, in a first back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from one end thereof. Still further, the method includes discharging, in a second back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from the other end thereof.-

Abstract: A method includes producing a first blended low salinity injection water for injection into at least one injection well that penetrates a first region of an oil-bearing reservoir and producing a second blended low salinity injection water for injection into at least one injection well that penetrates a second region of an oil-bearing reservoir. The reservoir rock of the first and second regions has first and second rock compositions, respectively, that present different risks of formation damage. The first and second blended low salinity injection waters comprise variable amounts of nanofiltration permeate and reverse osmosis permeate. The compositions of the first and second blended low salinity injection waters are maintained within first and second predetermined operating envelopes, respectively, that balance improving enhanced oil recovery from the first and second regions while reducing formation damage upon injecting the first and second blended low salinity injection waters into the oil-bearing reservoir.

Abstract: An integrated system includes a desalination plant including a reverse osmosis (RO) array to produce an RO permeate blending stream and a nanofiltration (NF) array to produce an NF permeate blending stream. The integrated system also includes a blending system. a control unit, and an injection system for an injection well that penetrates an oil-bearing layer of a reservoir. The blending system is to blend the RO permeate blending stream and the NF permeate blending stream to produce a blended injection water stream.
The control unit is to dynamically alter operation of the blending system to adjust amounts of at least one of the RO permeate blending stream and the NF permeate blending stream to alter the composition of the blended injection water stream from an initial composition to a target composition.-
