Employees and contractors at our Brae platform add profitable production from the North Sea. Other core regions include the U.S., Canada and Equatorial Guinea.


Marathon requires contractors to comply with its Health, Environment and Safety (HES) policies, standards and guidelines, and monitors their HES performance on the job. Together, Marathon and its contractors strive for excellence in health, safety and environmental performance.
Marathon's HES Vision is aligned with our Core Values, including those relating to Corporate Governance, Ethics and Integrity, Diversity, and Philanthropy. Business decisions affecting HES are guided by our Code of Business Conduct.
This HES Vision is applicable to Marathon Oil Corporation and all majority-owned subsidiaries. Meeting this commitment is a responsibility shared by everyone, including all employees, contractors and third parties. To realize this vision, we will pursue continuous HES improvement using a suitable "plan-do-check-revise" management system to assess risks, set targets, and measure progress.
Marathon's HES Vision is straightforward:
