Gazprom Neft has been able to produce more than 25 million tons of oil in almost 10 years of operation of the Prirazlomnoye field in the Barents Sea. Prirazlomnoye oil field is the first and so far the only offshore field in the Arctic in Russia where commercial oil production has been underway since 2013. Recoverable reserves amount to 79 million tons. Further development of the field involves drilling ultra-complex wells over 7.5 km long.
