The Odoptu and Chayvo fields were still linked to the SODECO
project of the 1970s - which later became Sakhalin-1 - but a second project was created around the Lunskoye and Piltun-Astokhskoye fields - which became known as Sakhalin-2 (see map).
Because the Odoptu and Chayvo fields were still linked to SODECO
, a second project was created around the Lunskoye and Piltun-Astokhskoye fields--Sakhalin-II.
The Sakhalin-I project, in which SODECO
holds a 30% participating interest, develops and produces petroleum and natural gas from the Chayvo, Odoptu, and Arkutun-Dagi fields located off the northeast coast of Sakhalin Island, Russia, and has offloaded over 550 million barrels of crude oil from 2006 to date.
This consortium brings together the talents of major companies: ExxonMobil, SODECO
of Japan, ONGC of India, and the Russian state oil company Rosneft.
Other Sakhalin-1 co-venturers are the Japanese company SODECO
(30 percent); the Indian company ONGC Videsh Ltd (20 percent); and two Russian companies, SMNG-Shelf (11.
Other co-venturers include the Japanese company SODECO
(30 percent), and Russian companies SMNG-Shelf (23 percent) and Rosneft-Sakhalin (17 percent).
also owns 30% in the project, while Russian oil major Rosneft and ONGC hold 20% stakes each.
