US Patent 9914872 Proppants

Embodiments of proppants are described herein. In one embodiment, a proppant for hydraulic fracturing includes a proppant body. The proppant body has a length (L) and an outside diameter (D), and the proppant body length (L) to the proppant body outside diameter (D) ratio (L/D) is about 0.3 to about 5.0. The proppant body includes a space frame, and the space frame includes a plurality of rigid members creating a plurality of openings allowing fluid to flow through the proppant thereby increasing permeability. In another embodiment, a proppant for hydraulic fracturing includes a substantially cylindrical proppant body with a substantially circular cross-sectional area and an internal flow path with a substantially circular cross-sectional.
