Nano-Composite Resin Coated Proppant for Hydraulic Fracturing
Abstract. Proppant such as sand and ceramics is used in keeping the fractures open for hydrocarbon production in hydraulic fracturing operations. Its ability to withstand reservoir closure stresses and provide high conductivity is one of its key selection criteria. Sand is preferred over ceramics in unconventional plays due to its low cost and abundance. On the other hand, …
