Possibilities of Toxic Granular Solid Waste Disposal in Salt Solution Caverns

Oil and gas exploration and production activities produce large volumes of waste products that need to be managed properly. Post practices include technologies that still result in adverse environmental impacts. Until now, large volumes of solids and cuttings were disposed in shallow near surface facilities with fluids either being injected, or treated and discharged or land formed. Recent advancement in subsurface injection technology enables joint injection of liquids and solids into subsurface, but the disadvantage of this procedure is considerably high level of engineering necessary for size reduction of waste solids. Placement of solid wastes in dissolved caverns in salt is increasingly being viewed as an environmentally secure technology for disposal of low-toxicity wastes such as foundry sands (heavy metals), contaminated soil and other granular solid waste streams. The paper reviews siting considerations, cavern design and monitoring strategy to optimize cavern utilization and to demonstrate environmental security for waste containment.
