Abstract: A method to provide a plurality of fractures in a subterranean formation includes providing an essentially horizontal wellbore in the subterranean formation and providing a casing in the essentially horizontal wellbore. The method also includes providing communication between an inside of the casing and the subterranean formation at a plurality of locations along the length of the horizontal wellbore and providing a mortar slurry within the casing. The method further includes initiating a plurality of fractures from the plurality of locations and propagating the plurality of fractures by adding mortar slurry to the wellbore. A pressure inside the casing within the subterranean formation is above a fracture opening pressure while the plurality of fractures is propagating.

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.
