Waste disposal in hydraulically fractured earth formations

Patent ·
OSTI ID:6373775
A method is described for disposing of solids waste material in an earth formation comprising the steps of: defining a formation zone of interest which has at least one layer of earth material which is relatively permeable to fluid flow and an adjacent layer of earth material which is relatively impermeable to fluid flow there through; injecting a slurry including particles of said solids waste into said zone of interest at a pressure sufficient to hydraulically fracture said zone of interest in such a way that a fracture is formed which intersects said layers of earths material; and continuing the injection of said slurry to deposit a filter cake of said particles in said fracture adjacent to said layer of relatively permeable material and to form a relatively unobstructed flow path through said zone of interest adjacent to said layer of material that is relatively impermeable to fluid flow.
