Сахалин Энерджи
The original consortium, was a joint venture between Marathon Oil, Mc Dermott, and Mitsubishi. They won a tender from the Russian Government in 1992. Later that year Royal Dutch Shell and Mitsubishi joined the joint venture. In 1994 the JV incorporated in Bermuda to form Sakhalin Energy Investment Company Ltd. Sakhalin Energy, led by Marathon, negotiated the first PSA directly with representatives of the Russian government. The Russian Party maintained project planning and budget approval. The initial investment decision was to proceed with the oil field development led by Marathon. McDermott sold its share to the other partners in 1997 and Marathon traded its shares to Shell for an interest in other properties (the BP operated Foinaven field, near the Shetland Islands, and an eight block area in the Gulf of Mexico—including the Ursa field) in 2000.
