Environment

We believe protecting the environment is critical to operational excellence, and that compliance with regulations and laws is not negotiable.

Management Approach

We manage our environmental risks using the Responsible Operations Management System and strive to continuously improve our environmental performance. The executive vice president of operations has overall leadership accountability for our environmental performance, with oversight from the Health, Environmental, Safety and Corporate Responsibility (HES&CR) Committee of the board of directors.

To eliminate or reduce environmental impacts from our operations, we develop sound practices for local and regional management of emissions, water and waste. Through environmental management strategies and processes, we:

  • Promote compliance with all applicable regulations. In the absence of fully developed regulatory structures, we follow World Bank Guidelines in effect at the time of facility design and project execution.
  • Identify, evaluate and implement potential solutions to reduce air emissions, waste and freshwater use and to prevent spills.
  • Track and report environmental performance data and management practices to internal and external stakeholders.

Performance

We are committed to reduce spills and releases to the air and water, minimize wastes, and promote responsible water management and land stewardship. Reducing our operational impact on the environment also can reduce costs, improve efficiency, allow employees to focus on producing oil and gas safely and cost-effectively, and have other business benefits.

In 2017, we:

  • Served as a founding member of The Environmental Partnership, which is committed to continuously improving the industry’s environmental performance.
  • Cut methane intensity by over 50 percent in our Oklahoma asset, meeting our target set in 2016.
  • Promoted compliance by finalizing implementation of an electronic system for tracking applicable regulations and associated tasks.
  • Increased water consumption from 29 million barrels in 2016 to 70 million barrels, primarily due to entry into the Permian Basin, higher activity levels in other U.S. resource plays and use of completion designs that required more water.
  • Took action to reduce waste and minimize freshwater use in the Permian Basin, including building a 300,000-barrel produced water recycling facility within six months of entry, treating and reusing produced water in stimulation jobs within three months of entry, and working to make produced water an economic supply source during droughts.
  • Recorded all-time low number of spills in our conventional assets in both count (8 spills) and total volume (66 barrels).
  • Recorded lower spill volumes to the environment year over year in our established resource play assets – Bakken, Eagle Ford and Oklahoma.
  • Increased solid waste disposal 63 percent due to higher volumes generated by the addition of our new Permian Basin asset, Brae Bravo decommissioning and incinerator ash in Equatorial Guinea.
