Rowlan Greaves is a senior staff engineer with Southwestern Energy’s Government & Regulatory Affairs team. He manages the company’s Freshwater Neutral program, which seeks to restore equal volumes of freshwater used in operations back to the environment. Greaves’ expertise in water management has helped Southwestern attain top marks for transparency in its water and chemicals practices.
Prior to joining Southwestern Energy in 2010, Greaves held project management roles at Tyco Thermal Controls and URS Corporation with an emphasis on water resources and liquids management. He also currently serves as Secretary of the Energy Water Initiative (EWI), a collaborative effort among oil and gas operators to study and improve water use and management across the industry. He holds a bachelor’s degree in civil engineering from Texas A&M University.
Water Resources Management & Stewardship
Water is a precious resource. It is vital for healthy communities, environments and businesses. As such, expectations are high for oil and gas companies to operate in a responsible and transparent manner – particularly when it comes to the use of water resources shared by many. This presentation will discuss elements associated with water management in the unconventional oil and gas space, including the freshwater neutral program utilized by Southwestern Energy.
Responsible water management starts with safe operations that protect personnel, the community and the environment. This includes equipment, best practices and a culture that enables and encourages top-tier fluids control and management. A key component of water management for most oil and gas operators is the efficient reuse of produced water back into operations, to the degree feasible and economically viable. The percentage of reuse is variable depending upon a number of factors such as the geographic setting, water cut of the reservoir, salinity of the produced water, and suitability for treatment. If available, other non-potable water sources may be considered for use with operations, which provides an additional environmental benefit of reducing freshwater usage for downhole well stimulations.
While the availability of water is of critical importance for unconventional oil and gas development, there are ways in which freshwater can be beneficially returned to the environment. One way is through water treatment and discharge, if economics and regulatory pathways allow. Another is through collaborative support and investment in conservation projects to restore or enhance aquatic waterbodies and habitats.
