Devon Energy Corporation (Devon) is one of the largest independent oil and gas companies in North America. The company is primarily engaged in the exploration, development and production of crude oil and natural gas resources in the US and Canada. Its exploration and production (E&P) activities in the US are located in the Mid-Continent, Permian Basin, Gulf Coast and the Rocky Mountains regions. Devon’s Canadian Operations are located in the Horn River Basin, Deep Basin, Foothills, Central, Northwest and Lloydminster areas and the thermal oil sands projects in Alberta. Earlier, the company was also involved in offshore operations in the Gulf of Mexico and other international markets such as China, Brazil, Azerbaijan and other international locations. However, Devon announced its plan to restructure operations in November, 2009 by concentrating its E&P activities on North American onshore fields and divesting its offshore international operations. The company sold off its non-core offshore operations during Q4 2009–Q2 2011; since then, all its E&P activities are located onshore in North America.
