<p>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°F and that resists degradation at temperatures of about 300°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°F or higher.</p> |
