Patent ID: 8765646

Claim:
A method, comprising: combining a carrier fluid and a solids mixture to form a preferably flowable slurry, wherein the solids mixture comprises a plurality of volume-averaged particle size distribution (PSD) modes, wherein a first PSD mode comprises solids having a volume-average median size at least three times larger than the volume-average median size of a second PSD mode such that a packed volume fraction (PVF) of the solids mixture exceeds 0.75, and wherein the solids mixture, preferably the second PSD mode, comprises a degradable material; circulating the slurry through a wellbore to form a pack of the solids mixture having a PVF exceeding 0.75 in one or both of a fracture in a formation and an annulus between a screen and the wellbore; degrading the degradable material in the pack to increase porosity and permeability of the pack; wherein the second PSD mode comprises a water-soluble solid, and the carrier fluid comprises an invert emulsion wherein the water-soluble solid is dispersed in an oil phase, and the degradation comprises breaking the emulsion to dissolve the water-soluble solid in an aqueous medium; and producing a reservoir fluid from the formation through the increased porosity pack.
