Patent ID: 8127849

Claim:
A sand control method for a wellbore penetrating a subterranean formation, comprising: introducing into the wellbore a slurry of a composite and a carrier fluid, wherein the composite comprises polyamide particulates having an apparent specific gravity (ASG) between from about 1.05 to about 2.00; placing the composite adjacent the subterranean formation to form a fluid-permeable pack capable of reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore wherein at least one of the following conditions prevail: (a) the composite exhibits crush resistance under conditions as high as 10,000 psi closure stress; (b) the composite further comprises a non-reactive filler and further wherein the crush resistance and thermal stability of the composite is greater than the crush resistance and thermal stability of a substantially similar composite which does not contain the non-reactive filler; or (c) the composite further comprises a non-reactive filler and further wherein the composite is prepared by blending the polyamide particulates with the non-reactive filler in a molten state.
