A study was conducted to investigate applied ion analysis of water used at various stages in the energy extraction industry. It was demonstrated that energy extraction involved the use of fluid and material to create or restore small fractures in a formation in order to stimulate production from new and existing oil and gas wells. This created paths that increased the rate at which fluids could be produced from the reservoir formations. The study focused the required analytical parameters and techniques for water used in the process of hydraulic fracking. There were three stages in which water analysis was required, such as fracking fluid, flowback water or produced water, recycled water or make-up water for fracking fluids, and wastewater. The pH of a sample was determined electrometrically using either a glass electrode in combination with a reference potential or a combination electrode. Source
