“Recognizing the latent value within produced water can offer tangible solutions to some of the world’s most pressing environmental challenges, from COemissions to the increasing scarcity of certain minerals and water itself,” said Samouei, a research assistant professor in the Harold Vance Department of Petroleum Engineering.
In 2020, the annual global quantity of produced water recovered from oil and gas operations surpassed 240 billion barrels, with Texas alone recovering 33 million barrels daily. The oilfields of the Permian Basin in Texas generate more produced water than all other U.S. shale plays combined. Treating this vast volume is cost-prohibitive, so produced water is mainly considered a waste product and injected in subsurface disposal fields for safe containment.
Much of his current research centers on developing the best flow of methods for extracting valuable minerals from brine in stages of refinement using COdesalination, which he says is “a groundbreaking approach to targeted mineral recovery from produced water.” The process includes a variety of filtration techniques, such as ultrafiltration and nanofiltration, and even utilizes reverse osmosis.
