摘要： A diverter fluid includes an aqueous carrier fluid, and a plurality of water-swellable polymer particles having a size of 0.01 to 100,000 micrometers. A method of hydraulically fracturing a subterranean formation penetrated by a reservoir includes injecting a fracturing fluid into the formation at a pressure sufficient to create or enlarge a fracture, injecting a diverter fluid into the formation, and injecting a fracturing fluid into the formation, wherein the flow of the fracturing fluid is impeded by the diverting agent and a surface fracture area of the fracture is increased. A method of controlling the downhole placement of a diverting agent is also disclosed, including injecting a diverter fluid including the diverting agent and an aqueous carrier fluid selected so that the polymer particles are fully swelled after contacting the aqueous carrier fluid for an amount of time sufficient to achieve a desired downhole placement.
