MOSCOW – The Sakhalin-1 partners Rosneft and ExxonMobil have installed the Berkut drilling platform over the Arkutun-Dagi field in the Okhotsk Sea offshore eastern Russia. Water depth is 35 m (115 ft).
Plans are for a drilling rig optimized for year-round operations at the far north location to drill 45 wells with a radius of up to 7 km (4.3 mi) from the platform.
Production from the field is expected to start in December.
According to Rosneft, the Berkut platform was designed for work in harsh sub-arctic conditions and to withstand waves up to 18 m (59 ft) high, ice floe pressure up to 2 m (6.6 ft) thick, and temperatures down to -44°C (-47°F).
Sakhalin-1 was the first shelf project approved by the Russian Federation on PSA terms in 1996.
The development takes in three fields, with Chaivo and Odoptu already in production. Operations could continue through 2050.
