▎ 摘　　要

NOVELTY - Servicing (M1) a wellbore extending from a surface of the earth and penetrating a subterranean formation, comprises: recovering an aqueous-based wellbore servicing fluid from the wellbore; and removing water from the aqueous-based wellbore servicing fluid by contacting the aqueous-based wellbore servicing fluid with a porous substrate coated with a hydrophilic and oleophobic coating (41), where the water is removed from the aqueous-based wellbore servicing fluid via passage through the porous substrate, the water removed via passage through the porous substrate coated with the hydrophilic and oleophobic coating comprises a salt content, as measured by electrical conductivity, of less than or equal to5000 ppm, and a water concentration and a volume of the aqueous-based wellbore servicing fluid are reduced and a density of the aqueous-based wellbore servicing fluid is increased to provide a modified aqueous-based wellbore servicing fluid. USE - The methods are useful for servicing a wellbore extending from a surface of the earth and penetrating a subterranean formation. ADVANTAGE - The methods: improve water base wellbore servicing (e.g. drilling) fluids management; reduce waste and manage drilling fluid density; manage fluid volumes in a mud plant and potential fluid density and volumes at a rig site and provide for the production of heavier water based fluids with barite additions; and enable recovery of potable water and/or the production of a reduced volume of waste material needing disposal. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) servicing (M2) a wellbore extending from a surface of the earth and penetrating a subterranean formation, comprising recovering an aqueous-based drilling fluid from the wellbore, removing water from the aqueous-based drilling fluid by contacting the aqueous-based drilling fluid with a porous substrate coated with a hydrophilic and oleophobic coating, where the water is removed from the aqueous-based drilling fluid via passage through the porous substrate, the water removed via passage through the porous substrate coated with the hydrophilic and oleophobic coating comprises a salt content, as measured by electrical conductivity, of less than or equal to5000 ppm, and a water concentration and a volume of the aqueous-based drilling fluid are reduced and a density of the aqueous-based drilling fluid is increased, and adding a weighting material to the aqueous-based drilling fluid after the removing of the water from its; and (b) servicing (M3) a wellbore extending from a surface of the earth and penetrating a subterranean formation, comprising recovering a spent fluid from the wellbore, forming a concentrated composition by removing a portion of water from the spent fluid recovered from the wellbore, where the portion of the water is removed by contacting the spent fluid with a porous substrate coated with a hydrophilic and oleophobic coating, the water is removed from the spent fluid via passage through the porous substrate to provide the concentrated composition, the water removed via passage through the porous substrate coated with the hydrophilic and oleophobic coating comprises a salt content, as measured by electrical conductivity, of less than or equal to5000 ppm, and the concentrated composition has a water concentration and a volume that are less than a water concentration and a volume of the spent fluid, respectively, and a density that is greater than a density of the spent fluid, and transporting the concentrated composition to a disposal location remote from the wellbore and disposing of its.
