    摘要： A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) wherein the proppant comprises from 1 to 100 percent in weight of stiff, low-elasticity and low-deformability elongated particles (34) and proppant-spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The channelant can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include fibers to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

    摘要： A proppant material is provided that is in the form of generally rigid, elastic plate-like particles having a maximum to minimum dimension ratio of more than about 5. The proppant may be formed from a corrosion resistant material or having a corrosion resistant material formed thereon. The plate-like particles may be substantially non-deformable and may be formed from stainless steel or carbon steel provided with a corrosion resistant coating. The particles may have a thickness of from about 100 to about 300 μm and may be in the form of a grating. A method of hydraulic fracturing in a formation penetrated by a wellbore is also provided wherein proppant material in the form of generally rigid, elastic plate-like particles having a maximum to minimum dimension ratio of more than about 5 are introduced into the wellbore. The particles may be formed from a corrosion resistant material or having a corrosion resistant material formed thereon. Non-plate-like proppant may be introduced into the wellbore in conjunction with the plate-like proppant.
