摘要
Methods of treating a fracture in a subterranean formation including providing a proppant-free fluid comprising a first gelling agent and providing a proppant fluid comprising a second gelling agent and proppant aggregates. The proppant-free fluid and the proppant fluid are substantially immiscible. The proppant-free fluid is continuously pumped into the subterranean formation and the proppant fluid is continuously pumped into the subterranean formation, such that the proppant-free fluid and the proppant fluid are present simultaneously in a portion of the subterranean formation but remain immiscible. The proppant aggregates are then placed into a portion of the fracture in the subterranean formation to form a proppant pack having proppant-free channels therein.
