Abstract
A subterranean formation is treated by injecting a blend of fracture proppant material and deformable particulate material into the formation. The deformable particulate material may combine with the fracture proppant material to increase fracture conductivity, reduce fines generation, and/or reduce proppant flowback. The fracture proppant material may be a material such as sand, and the deformable particulate material may be a material such as polystyrene divinylbenzene beads.
Claims105
A method of treating a subterranean formation, comprising:
- injecting a fracturing fluid composition into said subterranean formation, wherein said fracturing fluid composition comprises a blend of a fracture proppant material and a deformable beaded material, wherein in said formation individual particles of said deformable beaded material yield upon point to point stress with particles of said fracture proppant material.
