Navigating the complex labyrinth of contemporary energy and environmental issues requires a firm understanding of legal and policy concepts of oil and gas development. This course examines the legal and regulatory framework of domestic and international upstream and downstream oil and gas activities. The course explores key domestic statutory and common law sources, as well as regulations. It also surveys selected international and comparative materials such as joint field development agreements and arbitral decisions. The course maintains an environmental perspective and examines several important case studies such as the proposed Keystone XL pipeline, hydraulic fracturing (fracking) activities in the Marcellus Shale, and Arctic offshore hydrocarbon development.
