Devon’s exploration strategy has evolved significantly over the last 15 years. Prior to 2004, it was dominated by acquisitions, mergers, and low-risk exploration. The company then attempted to balance its low-risk, near-term projects with high-impact conventional exploration. Devon subsequently divested its Gulf of Mexico (GoM) and international assets in 2010 to focus on growing production and reserves from its North American unconventional and Canadian oil sands projects. In early 2019, Devon announced plans to divest its Canadian and Barnett Shale positions, in line with its strategy to focus on high-return tight oil assets in the US. In June 2019, Devon completed the sale of its Canadian assets to Canadian Natural Resources Limited. Devon's remaining Barnett position remains on the market at the time of publication, with the company aiming to complete its divestment by the end of the year.
