Chornomornaftogaz
Chornomornaftogaz (also: Chernomorneftegaz, , , lit. "Black Sea oil and gas") is an oil and gas company located along Krymgazseti in Simferopol, Crimea. It is legally a subsidiary of Ukraine's state-owned oil and gas company Naftogaz. However, after the 2014 Crimean crisis it was seized by the region's parliament in the run-up to its annexation by Russia. There was also a privately owned oil company Chernomorneftegaz, registered in Moscow in 1998 and purchased by Rosneft in 2011, which is not linked to Chornomornaftogaz. History. The company was established with the order of the Ministry of Gas Industry  of the USSR on October 20, 1978 №209-org to develop oil and gas resources in the Black Sea and the Sea of Azov. In February 2014, Ukraine's state-owned oil and gas company Naftogaz sued Chornomornaftogaz for delayed debt payments of 11.614 billion UAH (almost €1 billion) in the Economic Court of the Crimean Autonomous Republic. In March 2014, Crimean authorities announced that they would nationalize the company. Crimean deputy prime minister Rustam Temirgaliev said that Russia's Gazprom would be the new owner. A group of Gazprom representatives, including its head of business development, has  been working at the Chornomornaftogaz head office since mid-March 2014. Formally, nationalized assets were transferred to the newly established company Crimean Republican Enterprise Chernomorneftegaz, which was later reorganized into state unitary enterprise Chernomorneftegaz. On 11 April 2014, the U.S. Treasury's Office of Foreign Assets Control announced that it had added Chornomornaftagaz to the Specially Designated Nationals and Blocked Persons List as part of the U.S. sanctions against Russia. Reuters quoted an anonymous U.S. official who explained that the United States wanted to make it impossible for Gazprom to "have dealings with Chornomornaftogaz", and if that were to happen , Gazprom itself could face sanctions. The European Union followed suit on 13 May 2014, the first time its sanctions list has included a company. Naftogaz has considered to file a suit against Russia in international arbitration for a compensation for the seized company. In December 2015, Chornomornaftogaz moved two jack-up rigs—Tavrida and Petro Hodovanets—from Odeske gas field to Russian territorial waters due to disputed status of the field and a risk that rigs will be arrested by the Ukrainian authorities.
