Patent ID: 8662172

Claim:
A method for treating a subterranean formation penetrated by a wellbore, comprising: combining a carrier fluid, a first amount of particulates, a second amount of particulates and a third amount of particulates into a slurry; wherein the first amount of particulates have a first average size distribution and the second amount of particulates have a second average size distribution, and wherein at least one of the first amount of particulates and the second amount of particulates comprise an expanding material, and wherein the third amount of particulates comprise a degradable material; placing the slurry in the wellbore; lowering a screen into the slurry; forming a gravel pack in an annulus between the screen and a surface of the wellbore; degrading the degradable material to increase permeability of the gravel pack and reduce a volume of the gravel pack; expanding the expandable material to increase a volume of the gravel pack in the wellbore; and thereafter injecting or producing a fluid through the gravel pack.
