摘要： 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.

摘要： 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.

摘要： A method for selecting an aqueous displacement fluid comprising an aqueous solution of dissolved phosphate species includes obtaining reservoir parameters for a reservoir, receiving an input comprising a permitted loss of dissolved phosphate species resulting from mixing of the aqueous displacement fluid and resident water following injection of a selected pore volume of the aqueous displacement fluid, selecting an aqueous displacement fluid, and determining that a composition of the aqueous displacement fluid is within an operating envelope using the reservoir parameters and the permitted loss of dissolved phosphate species. The reservoir parameters include physical characteristics of the reservoir and chemical characteristics of the resident water. The operating envelope defines boundary conditions for one or more parameters of the composition of the aqueous displacement fluid to limit a loss of dissolved phosphate species upon injection into the reservoir to less than or equal to the permitted loss.

摘要： A method for analysing a crude oil to determine the amount of organic acid compounds contained in the crude oil includes extracting the organic acid compounds from a sample of crude oil to form an extract and determining the amount of the extracted organic acids In addition, the method includes dissolving the extract in a polar solvent to form a solution of the extracted organic acid compounds Further, the method includes introducing a sample of the solution of the extracted organic acid to an apparatus including a reversed phase liquid chromatography (LC) column and a mass spectrometer (MS) arranged in series. The reversed phase LC column contains a hydrophobic sorbent and the mobile phase for the LC column includes a polar organic solvent. Still further, the method includes separating the organic acid compounds in the LC column of the LC-MS apparatus and continuously passing the separated organic acid compounds from the LC column to the MS of the LC-MS apparatus to ionize the organic acid compounds and to obtain a chromatogram with mass spectral data over time for the ionized organic acid compounds. Moreover, the method includes determining the area(s) under the peak(s) in an extracted ion chromatogram derived from the mass spectral data assigned to one or more organic acid compounds. The method also includes determining the amount of the organic acid compound(s) in the sample by comparing the area under the peak(s) assigned to the organic acid compound(s) with the area under a peak in an extracted ion chromatogram assigned to a specific amount of a standard organic acid compound. In addition, the method includes extrapolating from the amount of the organic acid compound(s) in the sample to provide the total amount of the organic acid compound(s) in the extract.

摘要： A method for recovering crude oil from a reservoir including at least one layer of reservoir rock having crude oil and a formation water within the pore space thereof includes injecting into the layer(s) of reservoir rock from an injection well, alternating slugs of an aqueous displacement fluid comprising a concentrated solution of a water-soluble additive in an aqueous solvent and of an aqueous spacer fluid. The number of injected slugs of aqueous displacement fluid, n, is in the range of 15 to 1000 per swept pore volume, PVR, of the layer(s) of reservoir rock. The injected pore volume of each individual slug, PVSlug-i, of aqueous displacement fluid is in the range of 10−12 to 10−2 of the swept pore volume, PVR, of the layer(s) of reservoir rock. The total injected pore volume of the slugs of aqueous displacement fluid is in the range of 10−8 to 10−1 of the swept pore volume, PVR, of the layer(s) of reservoir rock. The injected pore volume of each individual slug of aqueous spacer fluid, PVSpacer-i, is in the range of 0.0001 to 0.1000 of the swept pore volume, PVR, of the layer(s) of reservoir rock. The total injected pore volume of the slugs of aqueous spacer fluid is in the range of 0.9000000 to 0.9999999 of the swept pore volume, PVR, of the layer(s) of reservoir rock. The reservoir rock has a dispersivity, α, in the range of 1 to 30% of the interwell distance between the injection well and production well. The amount of additive delivered to the layer(s) of reservoir rock by the plurality of slugs of aqueous displacement fluid is equal to or greater than a predetermined minimum additive quantity (MAQ).
