Claim Text:
1. A method comprising: preparing a hydraulic fracturing fluid that comprises a proppant mixture; adjusting the hydraulic fracturing fluid to a flow pattern operable to distribute a substantially equal distribution of an amount of proppant from the proppant mixture into a plurality of fracture clusters formed in a subterranean zone; and distributing the hydraulic fracturing fluid in the substantially equal distribution of the amount of proppant from the proppant mixture into the plurality of fracture clusters, each of the plurality of fracture clusters formed in the subterranean zone at a unique depth from a terranean surface; wherein adjusting the hydraulic fracturing fluid comprises inducing a laminar flow regime in which proppant materials with lower specific gravities move toward an outer annulus of the flow pattern while proppant material with higher specific gravities move toward a center of the flow pattern.
