Wintershall Holding GmbH is a wholly-owned subsidiary of BASF Group.
Wintershall is Germany's largest internationally active crude oil and natural gas producer. The company explore and produce oil and gas in Europe, North Africa, South America, Russia, and the Middle East.
They have been active for over 85 years and have a workforce in excess of about 2,000 employees from more than 50 nationalities.
In the autumn of 1990 Wintershall started cooperation with the Russian gas company, Gazprom, and concluded a long-term agreement on the marketing of Russian natural gas in Germany.
In 1993, WINGAS GmbH, the joint venture of Wintershall (50% plus one share) and Gazprom (50% minus one share) was established.
In 2005, Wintershall, Gazprom and E.ON Ruhrgas agreed to build the Nord Stream natural gas pipeline from Russia to Germany.
In 2006, Wintershall got a stake in Yuzhno-Russkoye gas field.
In September 2015, Wintershall's parent group BASF traded 100% of the company's gas distribution and storage business and 50% of its gas exploration arm, Wintershall Noordzee, for 25%-plus-one-share of Gazprom's Achimov deposits in Western Siberia's Urengoy oil, gas and condensate field. BASF had in 2013 signed a memorandum of understanding on the assets swap but the deal ran into trouble because of US and EU sanctions against Russia.
Under a binding contract signed on September 4, 2015, by Gazprom chair Alexey Miller and his opposite number at BASF, Kurt Bock at the Russian government's Eastern Economic Forum in Vladivostok, the German group would invest in and develop Blocks 4A and 5A of the Achimov gas and gas condensate deposits in the Urengoy gas field with Gazprom.
