Traditional approaches to treating zinc from completion fluid flowback and produced water are cumbersome and costly, with potential for perpetual liabilities associated with onshore in-ground disposal. The system's treatment process canĪbstract This paper and its presentation provides an overview of an innovative way to treat zinc-contaminated water that might, for example, result from the use of completion fluids with extremely dense zinc bromide-up to 19.2 pounds (8.7 kilograms) per gallon-in high-pressure wells. residual zinc-contaminated fluid canīe produced months after completion operations are finished.
