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： 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.
