Wintershall, which has its headquarters in Kassel, has been active in the exploration and production of oil and gas for more than 75 years and is now Germany's largest producer of crude oil and natural gas. In its exploration and production activities, Wintershall deliberately focuses on selected core regions where the company possesses a wealth of regional and technological expertise.
