摘要： An oil recovery process that utilizes one or more filtration media having an efficiency of 30% or greater for particles of 1 micrometer size or greater and a flow rate of 2 milliliters per minute per centimeter squared of media per unit pressure of the liquid (ml/min/cm2/kPa) to remove silica and/or oil and/or dissolved organics and/or dissolved solids from produced water which includes separating oil from the produced water and precipitating silica into particles and wherein the produced water having the precipitated silica is directed to a filtration medium which operates in a direct flow filtration mode and removes the precipitated silica from the produced water to form a permeate stream.

摘要： An oil recovery process that utilizes one or more filtration medium comprises a filter cake and a second filtration medium being nonwovens sheet to remove silica and/or oil and/or dissolved organics and/or dissolved solids from produced water which includes separating oil from the produced water and precipitating silica into particles and wherein the produced water having the precipitated silica is directed to a filtration medium which operates in a direct flow filtration mode and removes the precipitated silica from the produced water to form a filtrate stream.

摘要： A process for the extraction and recovery of bitumen from oil sands and a process for the treatment of tailings are disclosed. Bitumen is recovered in a process comprising contacting a polysilicate microgel with an ore sand oil to produce a froth comprising bitumen and a tailings stream comprising water, sand and clay fines. Preferably the tailings stream is dewatered and recovered water may be recycled to the extraction process. Polysilicate microgel may be carried through to a dewatering step and enhances flocculation in dewatering said tailings.

摘要： A method for recovering and treating hydrocarbon fluids using a hydraulic fracturing process wherein a fluid stream containing liquid or gaseous hydrocarbon species or both, produced water, suspended solids, and dissolved contaminants is recovered from a well. Hydrocarbon species are separated from the fluid stream to produce a second fluid stream comprising liquid water, which is then directed to a filter medium and essentially all of the second fluid stream passes through the medium to produce a permeate stream and a filter cake, and the filter cake is separated from the medium and disposed of separately.
