Exxon Mobil Corporation and its partners in the Sakhalin-1 consortium have begun production at the Sakhalin-1 project’s Arkutun-Dagi field—the last of the three sub-Arctic offshore Sakhalin Island in the Russian Far East to be developed. Peak daily production from the field is expected to reach 90,000 barrels.
The field will bring total daily production at Sakhalin-1 to more than 200,000 barrels. The other two fields—Chayvo and Odoptu—began production in 2005 and 2010, respectively.

Production from Sakhalin-1’s Arkutun-Dagi field will be routed through the existing Chayvo onshore processing facility on Sakhalin Island and delivered through pipelines to the De-Kastri oil export terminal located in Khabarovsk Krai, Russia.

Exxon Neftegas Ltd. is the Sakhalin-1 Consortium operator with 30%t interest. Coventurers include Sakhalin Oil and Gas Development Co. Ltd., with 30% interest, and affiliates of Rosneft, the Russian state-owned oil company, RN-Astra with 8.5%, Sakhalinmorneftegas-Shelf, with 11.5%, and ONGC Videsh Ltd. with 20%.
Arkutun-Dagi field is located about 25 km (15.5 miles) from the north-eastern shore of the Sakhalin island in the sea of Okhotsk. According to the development simulation model, the existing world’s most powerful drilling platform provides for well drilling with horizontal displacement of not less than 7 km (4.4 miles). As a result, the platform virtually appears as a giant multiple well platform, which allows maximum efficient offshore development.
