Abstract: A method to provide fractures in a formation includes providing a wellbore in the formation and providing a casing in the wellbore. The method also includes providing communication between an inside of the casing and the formation and initiating a fracture from the communication between the inside of the casing and the subterranean formation. The method further includes propagating the fracture with a fluid comprising mortar slurry. The mortar slurry comprises water and hydraulic material, and at least 50 percent of the water is consumed to hydrate the hydraulic material.

Abstract: A method to provide a fractured subterranean formation includes providing an essentially horizontal wellbore in the subterranean formation and providing fractures in the subterranean formation using a plurality of fracturing fluids. At least one of the fracturing fluids has a specific gravity that exceeds the fracture gradient within the subterranean formation and at least one of the fracturing fluids has a specific gravity that is less than the fracture gradient of the subterranean formation.
