Abstract
An improved proppant and a method of increasing the conductivity of the fractures of subterranean formations is described. The proppant contains a mixture of bondable particles and removable particles. The bondable particles within a subterranean formation, adhere to adjacent bondable particles to form a permanent, self-supporting matrix and the removable particles from the self supporting matrix the ambient conditions of the fracture. The conductivity of the fracture and the overall productivity of the hydraulic operation is increased.
