Water Sourcing

Range pioneered large-scale water recycling for shale gas development in Pennsylvania in 2009. Range aims to recycle to the maximum extent possible. Over the years, several iterations of technologies and best practices have been developed and employed as part of the Company’s water management plan.

For the Marcellus Shale play, Range implements a comprehensive water sourcing plan based on safety, best practices, and applicable laws and regulations. These plans address regional geology, topography, site location and water accessibility. Range has strategically focused on securing water for our operations from multiple abundant, drought-tolerant sources that include public water utility companies, the Ohio River, and the Susquehanna River in Pennsylvania.  Even though these are large sources, they are evaluated and regulated by the governing regulatory authorities; namely the Pennsylvania Department of Environmental Protection (PA DEP) and the Susquehanna River basin Commission (SRBC).  These regulatory authorities provide withdrawal and passby limitations on these sources to be protective of the environment as well as other users. To mitigate any possible operational impacts during low or restricted flow periods, Range has also invested in infrastructure to facilitate storage during peak flow periods. Range monitors water withdrawals and flow rates in accordance with regulations for all water withdrawal points.

Our area of unconventional operations within the Marcellus Shale is not regarded as a water scarce area due to the extensive fresh water resources in Pennsylvania. Our unconventional operations in Northern Louisiana are generally located within the Sparta Aquifer.  The Sparta is historically viewed as “depleted” from past use.  Range voluntarily does not utilize water from the Sparta aquifer for completions operations.

Range is constantly evaluating technologies and alternative fluid sources; such as municipal waste streams and acid mine drainage, but we have found that recycling of our own water as well as water from other local operators provides us the most opportunity and optionality.  Range aims to recycle to the maximum extent possible, which helps significantly reduce the amount of fresh water required, and improves capital efficiencies.
