Oil is now flowing from the last of three shallow water but very harsh environment fields developed by ExxonMobil in the sub-Arctic Sakhalin area off the east coast of Russia. Production from the Sakhalin-1 project’s Arkutun-Dagi field is expected to hit a peak rate of 90,000 b/d, says the operator. It is being produced via the ice-resistant Berkut (Russian for ‘Golden Eagle’) gravity base structure, the largest platform yet installed offshore Russia, with a topsides weight of circa 28,000 tons. Total production from Sakhalin-1 will eventually total more than 200,000 b/d, when added to the existing output from the other two fields, Chayvo and Odoptu, which began production in 2005 and 2010 respectively. The oil from Arkutun-Dagi is being routed through the existing Chayvo onshore processing facility on Sakhalin Island and delivered through pipelines to the De-Kastri oil export terminal in Khabarovsk Krai, Russia.
