ABSTRACT:
Compositions and methods are given for plugging of natural or artificially-created fractures in subterranean formations to reduce the flow of fluids. The compositions are mixtures of primarily inert particles of different sizes that leave a minimal flow path for fluids when the particles are packed in the fracture. If the fracture can close on the particles, the particles need not fill the width of the fracture before closure to cause plugging.
