A fluid that is useful in well stimulation operations, and in particular, in hydraulic fracturing treatments, comprises a carrier fluid; a proppant; and a polymeric viscosifier, which is typically a polymer with a melting temperature at least about 120 DEG F and that resists degradation at temperatures of about 300 DEG F. The polymeric viscosifier can be a polyolefin, particularly polypropylene or polyethylene. The fluid is especially useful in stimulating production in formations with a temperature of about 300 DEG F or higher. |
