Produced water is the major byproduct in the oil and gas industries. In oil and gas wells large quantities of naturally or injected water can be present. This water, which is trapped in the underground formations, is extracted to the surface during the production of the oil or gas. It contains hydrocarbons, salts, and various other components. Produced water is a growing source of concern due to environmental reasons. During CuriousU we will look at the several aspects associated produced water, and we will discuss and compares technologies that provide potential solutions to the problems it poses.
