FRACTURE HAVING A BOTTOM PORTION OF REDUCED PERMEABILITY AND A TOP PORTION HAVING A HIGHER PERMEABILITY

摘要

A method of fracturing a subterranean formation comprising: introducing a fracturing fluid into the subterranean formation to create or enhance a fracture comprising a bottom and top portion; introducing a first treatment fluid into the fracture, wherein after introduction of the first treatment fluid, at least a portion of the first treatment fluid remains in the bottom portion; and simultaneously introducing a second and third treatment fluid into the fracture after introduction of the first treatment fluid, wherein after introduction of the second and third treatment fluids, at least a portion of the second treatment fluid remains in the top portion, wherein after introduction of the first, second, and third treatment fluids, the bottom portion of the fracture has a first permeability and the top portion of the fracture has a second permeability that is greater than the first permeability. The first treatment fluid can create or enhance the fracture.
