A method of operating a filtration unit of a filtration system includes

Method of filtering water

A desalination system includes a desalination platform, a first skid disposed on a first deck of the desalination platform, the first skid including at least one of a first filtration unit configured to produce a first filtrate stream, and a first permeate unit configured to produce a first permeate stream, a first interconnecting pipework coupled to the first skid, and a first pipework support disposed on the first deck, wherein the first interconnecting pipework is disposed on the first pipework support.

Systems and methods for supplying low salinity injection water

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.

Method of controlling salinity of a low salinity injection water

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. Further, the integrated system includes a control unit. Still further, the integrated system includes an injection system for one or more injection wells that penetrate an oil-bearing layer of a reservoir. Moreover, the integrated system includes a production facility to separate fluids produced from one or more production wells that penetrate the oil-bearing layer of the reservoir and to deliver a produced water (PW) stream to the blending system. The blending system is configured to blend the RO permeate and NF permeate blending streams with the PW stream to produce a blended low salinity water stream. The control unit is configured 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 maintain a composition of the blended low salinity water stream within a predetermined operating envelope.

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.

Process and system for supplying a low salinity injection water

An integrated system includes The integrated system also includes a blending system. 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.
