ABSTRACT:
A method of propping fractures in a subterranean formation employing high-strength particles of propping agent having at least one passageway formed through each of the particles and having the usual high compressive strength and particle size range and density to enable emplacement in the fracture by hydraulic transport. Each particle has its at least one passageway formed substantially directly therethrough for increased permeability to flow of fluids from the subterranean formation. Particles may have any of the shapes that are commonly and economically available.
