Original Abstract Submitted
A method for preparing a wellbore treatment fluid includes contacting a fluid with a high temperature suspension additive to form the wellbore treatment fluid. The high temperature suspension additive can be a reaction product of at least one monomer, a thermally unstable crosslinker, and a thermally stable crosslinker comprising a compound with at least four functional groups. Also, the high temperature suspension additive can maintain a viscosity of the wellbore treatment fluid at a temperature of at least 250° F. (121° C.) for at least about 4 hours with a viscosity equal to or greater than about 25% of a peak viscosity.
