METHOD FOR RECOVERING HYDROCARBON FLUIDS FROM A HYDRAULIC FRACTURING PROCESS

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 and 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.
