Kimber Hamilton joined Marathon in March of 2002 as a process engineer and environmental professional. She was responsible for environmental compliance from a process engineering perspective. In 2005 she moved to a corporate support role providing a multitude of services including estimating greenhouse gas emissions for the then owned downstream components and representing Marathon in the regulatory advocacy process through participation in a variety of trade associations and committees. At that time she also provided compliance assistance to operating organizations on a variety of air, water and waste regulations. She moved to Norway in 2009 to implement process safety management in that then owned asset. At that time she had the unique opportunity to be involved in a rapidly growing asset as Marathon took operatorship of Alvheim FPSO in less than a year. In 2010 she was in Houston providing support for safety, environmental compliance, process safety, organizational change management, and management system implementation to international operations and non-operating organizations. Finally in 2014 she took the Environmental Supervisor role for the Eagle Ford Asset where she remains in at this time.
Kimber has worked in the oil and gas industry for over twenty years, seventeen of those with Marathon. She graduated from New Mexico State University with a Bachelor of Science degree in Chemical Engineering. Throughout her career Kimber has fulfilled many roles including Process Engineer, Process Safety Coordinator, Environmental Professional and Environmental Supervisor.

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.
