Slurry Fracture Injection is a waste disposal technology developed by Terralog Technologies Inc. Oilfield produced wastes, such as produced sand, slop, and tank bottoms, are mixed with water into a slurry which is then injected into deep unconsolidated sandstone formations above fracturing pressure. The solids are permanently emplaced within hydraulic fractures generated during the pumping process, and the carrying fluid subsequently drains into the high permeability formation.
