Wintershall Dea GmbH is a Germany-based exploration and production company focused on natural gas and crude oil. Formed in 2019 through the merger of Wintershall Holding GmbH and DEA Deutsche Erdoel AG, it is jointly owned by BASF SE and LetterOne. The company operates upstream assets across Europe, North Africa, Latin America, and the Middle East, with an emphasis on gas resources that supply regional energy markets and industrial consumers.
Beyond upstream activities, Wintershall Dea has interests in gas infrastructure and is involved in carbon capture and storage (CCS) and hydrogen-related initiatives aimed at reducing the carbon intensity of gas value chains. Its portfolio and expertise make it relevant to the chemical industry, where natural gas is both an energy source and a key feedstock for processes such as ammonia and methanol production.
