ABSTRACT:
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.
