Proppant is a small size ceramics ball, which are used to keep the artificial or hydraulic fractures to keep the shale rocks fractures open. It prevents opened fracture from closing on release of pressure. They help in oil and gas production by forming a conduit for hydrocarbons to flow more freely through. It comes in a variety of shapes, sizes, densities, and quality, and it plays an important role in determining the eventual permeability of fissures.
