Water treatment processes make strides

摘要

As the water treatment of oilfield brines by desalination increases, the use of all desalination technique packages continues to grow. Combinations of chemical treatments, filtration, reverse osmosis (RO), and thermal, each playing a role, will become more standard operating practice in water treatment of oilfield brines. Dilution also will be used (if it is cost-effective and socially acceptable) to obtain the required water properties for reuse in frac fluid fabrication or environmentally acceptable discharge. All of these approaches will be applied in the effort to ensure that the water is reused to the maximum extent, reducing costs defined as financial, environmental, and social. In the process, these techniques will reduce the footprint on the locations where they are used and limit impact on the local communities.
