ABSTRACT:
A method of servicing a wellbore comprising placing a wellbore servicing fluid comprising a density segregation inhibitor composite into the wellbore, wherein the density segregation inhibitor composite comprises a high density additive and a low density additive; and wherein the high density additive comprises barium sulfate, iron oxide, manganese oxide, or combinations thereof. A method of inhibiting segregation of particles in a wellbore servicing fluid comprising preparing a composite material comprising a high density additive and a low density additive, wherein the low density additive comprises an elastomer which can increase in volume by greater than about 300% based on its original volume when contacted with a fluid.
