| description | Methods of treating a fracture in a subterranean formation including providing a proppant-free fluid comprising a first gelling agent; providing a proppant fluid comprising a second gelling agent and proppant aggregates, wherein the proppant-free fluid and the proppant fluid are substantially immiscible; continuously pumping the proppant-free fluid into the subterranean formation; continuously pumping the proppant fluid into the subterranean formation, wherein the proppant-free fluid and the proppant fluid are present simultaneously in a portion of the subterranean formation but remain immiscible; placing the proppant aggregates into a portion of the fracture in the subterranean formation so as to form a proppant pack having proppant-free channels therein. |
