Abstract
Compositions and methods are provided for plugging a fracture network in a wellbore. Exemplary compositions comprise a mixture of particles, some of the particles being degradable and other particles being elongated, having good compressive strength, and not being readily degradable at the conditions of the formation. The mixture of particles can temporarily bridge or plug fractures within the formation, and thus acts as a temporary diversion agent. After the degradable particles dissolve, the particles which are not readily degradable can remain in the fracture, helping to keep the fracture open and acting as a proppant.
