Fluids used in the hydraulic fracturing process consist primarily of 99.5% freshwater and sand. The remaining 0.5% is highly diluted additives found in common household products and the food we eat. Each additional additive serves a specific purpose, from limiting growth of bacteria to preventing corrosion of the well casing, to providing viscosity to help unlock the resources trapped in the solid rock. The amounts of these additives are adjusted depending on the type of rock, its geology and specifics of the well location. Fluids are mainly comprised of the following ingredients:
In addition to the ingredients listed above, there are small amounts of additional additives that are used for very specific and critical uses in the extraction process. Central to Sanchez Energy’s commitment to safe and responsible shale development is our support of public disclosure of these additives used in the hydraulic fracturing process. We disclose the additives we use through www.Fracfocus.org, which is an online registry managed by the Groundwater Protection Council (GWPC) and the Interstate Oil and Gas Compact Commission (IOGCC). These two organizations represent state regulators responsible for protecting local fresh water supplies and oversight of our daily operations.
