Since the expansion of hydraulic fracturing for oil and gas, use of freshwater resources as a hydraulic fracturing fluid has been increasing rapidly. As many areas across the U.S. are facing drought, the oil and gas industry will require water management strategies that maximize the use of non-potable water. In this study, the feasibility of using brackish groundwater reverse osmosis (RO) desalination reject concentrate and produced water as alternative water supply for frac fluid was evaluated. The results of water chemistries analysis showed a high concentration of alkalinity and sulfate in the RO concentrate. Also, significant concentrations of barium and calcium were observed in the produced water samples. Therefore, the down-hole scaling potential associated with different blend ratios of produced water and RO desalination concentrate were simulated using geochemical modeling software. Results showed possible calcite formation in all simulations. Simulations performed for the desalination concentrate showed less potential for barite formation, whereas a high potential for barite scale formation was observed in model simulations for the produced water (PW) and RO/PW blended samples. Finally, produced water dissolves rare earth elements (REE) as it flows through shale formations. Geochemical analyses of the Marcellus Shale have indicated that geothermal brines contain relatively high concentrations of REE. However, presence of high concentrations of barium can interfere with inductively coupled plasma - mass spectrometry (ICP-MS) analysis of produced water samples for REE due to the formation of polyatomic interferences. As an initial step towards assessing the feasibility of developing an economic strategic element recovery process, an accurate and reliable analytical ICP-MS method was developed to determine concentrations of REE in complex brine matrices with high barium concentrations. As a last step of this study, REE concentrations were analyzed in produced water and desalination concentrate samples.
