Abstract:
A method of treating a subterranean formation, comprising:injecting a blend comprising a fracture proppant material and a deformable particulate material into a subterranean formation, wherein individual particles of said deformable particulate material have a shape with a maximum length-based aspect ratio of equal to or less than about 5;wherein said individual particles of said deformable particulate comprise a material having a Young's modulus of between about 500 psi and about 2,000,000 psi at in situ formation conditions;wherein said individual particles of said deformable particulate material yield upon point to point stress with particles of said fracture proppant material under conditions of formation temperature and formation closure stress; said deformable particulate material also having a composition effective to substantially prevent total deformation of said individual particles upon said point to point stress under said conditions of formation temperature and formation closure stress.
