Title: HYDRAULIC FRACTURING AND FRAC-PACKING USING ULTRA-LIGHT, ULTRA-STRONG (ULUS) PROPPANTS
Abstract:
A method of fracturing or frac-packing a subterranean zone surrounding a well bore includes fracturing the subterranean zone with a fracturing fluid to form fractures; pumping proppant slurry comprising ultra-light, ultra-strong proppant into the fractures of the subterranean zone; and releasing pressure after pumping to form propped fractures. Particularly wherein the ultra-light, ultra-strong proppant has a specific gravity between 1.0 - 3.0 and a crush strength of 10,000 psi or higher.
