The exploration for oil and gas in Sakhalin-2 began in 1984. In 1986, Mitsui and McDermott formed a consortium, each side assuming 25 percent of the project cost. In 1991, Marathon Oil joined the consortium with a 37.5 percent share of the cost. In 1992, when the group acquired the rights to develop the fields, two more companies joined the project: Mitsubishi with a 12.5 percent share of the cost and Royal Dutch Shell at 25 percent. In April 1994, Sakhalin Energy Investment Company was formed to operate the project and to enter into a production sharing agreement with the Russian government. *9 Officially, the project's implementation commenced in April 1996. By that time McDermott had left the consortium. In 1998 a giant sea rig was installed in the Piltun-Astokhskoe field and the first oil is expected in 1999.
