    Abstract: A subterranean fluid containing formation, for example, a hydrocarbon reservoir, may be hydraulically fractured by pumping a novel fluid down a well bore penetrating the formation to contact the formation at sufficient pressure to cause fractures. The novel fracturing fluid comprises a fluid thickened with a particular type of amorphous colloidal silica. The fluid may have an aqueous or hydrocarbon base.

    Abstract: A method of secondary recovery of hydrocarbons which involves injecting a fluid into an injection well and producing hydrocarbons from a production well involves the use of a novel thickened injection fluid. The fluid comprises an intimate mixture of water, hydrocarbon solvent and colloidal silica. The fluid is miscible with hydrocarbons in the reservoir and aqueous fluids and provides a decreased mobility ratio to enhance sweep efficiency.
