Kazakhstan has sent Russia a request to resume oil supplies through the Druzhba pipeline, which has been suspended since May, the republic's energy minister, Arlen Akanzhanov, announced at a press conference. Druzhba is one of the largest oil gas pipeline systems in the world, designed to transport Russian and Kazakh oil to Eastern and Central European countries. Its total length is about 8.9 thousand km, including 3.9 thousand km passing through the territory of Russia. The capacity of the system is estimated at 1.2-1.4 million barrels per day.
