Treatment Enables High-TDS Water Use as Base Fluid for Hydraulic Fracturing

摘要

The beneficial use of produced water is receiving great attention in the oil and gas industry. As oil and gas are produced, large quantities of water containing high amounts of total dissolved solids (TDS) are produced in the process. Most of the high-saline produced water is reinjected into disposal wells. Reclaiming produced water as the base fluid for hydraulic fracturing not only helps to alleviate the industry's dependence on fresh water, but also lowers the overall cost of the fracturing treatment.
