  • Patent number: 6752208
    Abstract: Methods of reducing proppant flowback during production of fluids form subterranean formations are provided. Compressed sieves made from a shape memory material are introduced into hydraulic fracturing opera into hydraulic fractures in subterranean formations during hydraulic fracturing operations or subsequent thereto. The heat of the formation, or introduced heat, triggers the return of the sieves to their previous uncompressed shape and size. The sieves thereby wedge themselves into position within the fractures and serve to filter proppant and formation fines from produced fluids.
