Abstract: Embodiments of scalable systems and methods for treating and/or processing a variety of waste streams from any oil or gas exploration and/or production activity, including both fluid and solid wastes. In one embodiment, a water treatment facility and/or system comprises one or more input stations for receiving solid wastes and/or fluid wastes, one or more oil and water separation systems for separating oil and hydrocarbons from the fluid, and a plurality of water treatment processes and/or systems to remove solids from the fluid. In other embodiments, a solids treatment system is disclosed that can process solid wastes from any oil or gas exploration and/or production activity as well as the water treatment facility. The treated water and solids can be used for beneficial re-use applications (both off-site and on-site) without any deep well injection.
