Method for reducing fluid loss during hydraulic fracturing or sand control treatment

A low viscosity fluid for reducing fluid loss in a relatively low permeability formation has a viscosity of less that 10 CP and contains a low molecular weight viscosifying agent The aqueous medium may be fresh water, salt water, brine or slickwater. The invention has particular applicability when a...

More Information
Summary:A low viscosity fluid for reducing fluid loss in a relatively low permeability formation has a viscosity of less that 10 CP and contains a low molecular weight viscosifying agent The aqueous medium may be fresh water, salt water, brine or slickwater. The invention has particular applicability when an ultra lightweight (ULW) proppant or sand control particulate is employed. The fluid may be used in reservoirs having a relative permeability less than 10 mD.
