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. On 20 June 2022, when the 2022 Russian invasion of Ukraine was in full swing, Sergey Aksyonov announced that "the enemy" had struck an undisclosed Chornomornaftogaz production facility somewhere in the Black Sea near Tarkhankut, the southwestern cape of the peninsula. Aksyonov reported that there had been three strikes at three natural gas rigs.
