The future needs roots

The mining entrepreneurs Carl Julius Winter and Heinrich Grimberg found the company Wintershall. Its business in the initial years focused on mining potash salt. That also explains the company’s name: The Germanic word “Hall”, meaning salt, was appended to the surname of the founder Winter.

The legal predecessor of DEA Deutsche Erdoel AG is established as Deutsche Tiefbohr-Actiengesellschaft (DTA). The Managing Director is the 25-year-old merchant Rudolf Nöllenburg from Krefeld. The company initially operates as a drilling contractor. However, it would soon start drilling its own wells – including one that struck oil for the first time. Crude oil is officially declared the new main business in 1906; the company is renamed Deutsche Erdöl-Aktiengesellschaft (DEA) in 1911.

DEA Deutsche Erdoel AG drills the world’s first oil shaft, the Nöllenburg shaft, in Pechelbronn in Alsace. Up to then, oil was either extracted close to the surface or by means of wells. In the complex shaft construction method, however, oil is “mined” with the aid of an underground cavity.

Wintershall, which has now evolved into Germany’s largest potash company, expands from 1931 into crude oil production. The first step leads to Nienhagen near Hanover. DEA is also active there, so the two companies become direct rivals for the first time with neighbouring production derricks.

The history of Wintershall und DEA, two German companies both steeped in tradition, also includes their role during the era of National Socialism. As strategically important companies for the war economy, Wintershall and DEA benefit from the National Socialists taking over power. Forced labourers are used and exploited at both companies; the companies are also involved in producing oil reserves in Eastern and Southern Europe. To extensively reappraise this dark chapter in the companies’ history, take a critical look at it and assume the responsibility it implies, Wintershall initiated a project in 2018 together with the renowned Gesellschaft für Unternehmensgeschichte (Society for Business History) to look into the companies’ role in the era of National Socialism. The research also looks at the proximity of the companies’ management at that time to the NSDAP.

Crude oil production gets a boost, and the still young Federal Republic of Germany acquires a new and forward-looking branch of industry: in 1951 and 1952, Wintershall and DEA discover large natural gas reserves in Rehden and Pfungstadt. In the following decades, natural gas business becomes increasingly important. This is helped by the 1973/1974 oil crisis – a reminder that less dependency on Arabian oil sources is advisable.

Wintershall and DEA start their expansion abroad together after the Second World War. From 1954, they take part in developing oil and gas reserves in the Peruvian jungle. Both companies later cooperate, among other places, in Libya, Oman and Dubai.

DEA Deutsche Erdoel AG enters the Norwegian market. The target: the rich oil and gas reserves on the Norwegian continental shelf. They would later become one of Europe’s most important sources of energy.

Operations get underway in the Gulf of Suez: Oil production starts at the Ras Budran, Ras Fanar and Zeit Bay fields. That is the reward for ten years of work for DEA Deutsche Erdoel AG. Production off the Egyptian coast is one of the company’s earliest production projects outside Europe.

The oil price crises in the 1970s give a new boost to domestic oil reserves. From 1985, Wintershall and DEA are developing Germany’s largest oil field off the North Sea coast of Schleswig-Holstein as equal partners in a consortium. Production on a drilling and production platform designed specifically for the protection requirements of the Wadden Sea gets under way in 1987.

Wintershall concludes a long-term agreement for marketing Russian natural gas in Germany with the Russian company Gazprom. It marks the starting point of a cooperation comprising of pipeline projects and joint ventures to produce oil and gas in Russia and ends with the Russian war of aggression against Ukraine in 2022.

DEMINEX, a joint venture of the German mineral industry founded in 1969 to boost production abroad, is broken up. Wintershall takes over its regional activities in Russia, Azerbaijan and Argentina, and DEA its activities in Egypt and Norway – mainly countries that are still among Wintershall Dea’s core regions today.

Wintershall becomes operator of the Brage oil field and the Brage production platform, thereby significantly expanding its business in Norway with its first self-operated project on the Norwegian continental shelf and stakes in the Gjøa and Vega fields. Output climbs from 3,000 to 40,000 barrels a day – and the company grows by 240 employees.

Asset swap with Gazprom: Wintershall takes a stake in developing two further natural gas and condensate blocks in western Siberia. In exchange, the company transfers its entire natural gas trading and storage business to Gazprom and so focuses on its upstream operations.

Entry into the Mexican market: DEA Deutsche Erdoel AG takes a 50 per cent stake in the producing onshore oil field Ogarrio and becomes its operator. The company also acquires shares in Block 2 in the Gulf of Mexico. Thanks to further stakes, it establishes a major position in the national upstream market within just one year.

Wintershall and DEA Deutsche Erdoel AG become Wintershall Dea. The merger creates Europe’s leading independent oil and gas company. It holds concessions worldwide, has around 3,000 employees, and produces a combined 575,000 barrels of oil equivalent a day to begin with.

Wintershall Dea and the energy company Equinor launch the NOR-GE project. The aim is to develop a comprehensive and safe value chain for the capture, transport from the European mainland and subsea storage of CO2 (Carbon Capture and Storage - CCS) in the Norwegian North Sea. NOR-GE, along with the "Greensand" CCS project off the Danish coast and with hydrogen projects in Germany, is an important milestone for Wintershall Dea to contribute to the energy transition.

Wintershall Dea withdraws completely from Russia due to the Russian war of aggression on Ukraine. The company decided to leave the country in an orderly manner and in compliance with all applicable legal obligations.

Wintershall Dea CEO Mario Mehren says: "Wintershall Dea will terminate its activities in Russia. Continuing our business in Russia is not sustainable. Russia's war of aggression is not compatible with our values. It has destroyed cooperation between Russia and Europe."

For the first time ever in the EU, the entire CCS value chain is being implemented with project “Greensand”: In March 2023, the first injections of CO₂ are completed successfully on the Nini-platform off the Danish coast. This shows that it is possible to capture, transport, and store CO₂ safely and reliably across national borders and that the CCS technology will be able to contribute to a decarbonised future. 

As a leading member of the Greensand consortium Wintershall Dea collaborates with operator INEOS Energy and more than 20 other partners.
