A method for filling an annular area within a wellbore penetrated by a subterranean formation is provided. The method includes the steps of: (a) introducing a proppant into a wellbore to form a gravel pack of the proppant, wherein a specimen of the proppant has a non-globular and non-fibrous shape, and wherein the shape is further selected to provide the proppant the ability to bridge together such that the proppant has a maximum bridging span of at least 3 times larger than a largest overall dimension of the proppant specimen, where the maximum bridging span is the largest outlet hole diameter that the proppant can bridge under the weight of gravity; and (b) passing fluid through the gravel pack.
