Abstract
A method of treating a subterranean formation penetrated by a wellbore comprising injecting electrically conductive or electromagnetic fibers into the subterranean formation during hydraulic fracturing is provided. Suitable metallic materials, organic polymers, and organic polymers coated with or containing conductive or electromagnetic materials are described. The treatment is followed by measurement of resistivity and/or electromagnetic properties, optionally by a crosswell technique.
