Sakhalin Offshore Fields

The Sakhalin II (Сахалин-2) project, like its sister project Sakhalin-I, is a consortium to locate and produce oil and gas on Sakhalin Island and immediately offshore, in the Sea of Okhotsk, from two fields: Piltun-Astokhskoye and Lunskoye. Piltun-Astokhskoye is primarily an oil field, and Lunskoye is primarily a gas field. The project has been met with heavy criticism over the potential environmental impacts, which could include driving the world's last 100 remaining western pacific grey whales to extinction.

Marathon, McDermott and Mitsui formed MMM Consortium in 1991, Shell and Mitsubishi joined in 1992, to make it MMMMS. The consortium formed Sakhalin Energy Investment Company Ltd. (Sakhalin Energy) in April 1994 to develop and manage the Sakhalin II project.

The first ever Production Sharing Agreement (PSA) was completed with Russia in 1994, with the signing of the Sakhalin II project consortium. The consortium is managed and operated by Sakhalin Energy Investment Company Ltd. (Sakhalin Energy). McDermott sold its share to the other partners in 1997, and in 2000 Marathon traded its share to Shell for 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) and Marathon’s expenses in Sakhalin-II for that year.

In the Piltun-Astokhskoye field in July of 1999 production began from the Molikpaq platform, Vityaz Complex, and in September of 1999 the first crude was exported.

[edit] Consortium partners

  • 55% - Shell Sakhalin Holdings B.V. (Shell - UK/NETHERLANDS)
  • 25% - Mitsui Sakhalin Holdings B.V. (Mitsui - JAPAN)
  • 20% - Diamond Gas Sakhalin (Division of Mitsubishi - JAPAN)

The two field total project cost until 2014 was by Shell originally estimated at between $9 and $11 billion US dollars. However, the costs turned out to be substantially underestimated and in July 2005 Shell revised the estimate to $20 billion, causing much consternation among analysts and Russian business partners alike. There are six main phases to the project: field development in the Piltun-Astokhskoye oil field, field development in the Lunskoye gas field, upgrading infrastructure on the island (IUP — Infrastructure Upgrade Project) which includes a building pipeline to Prigorodnoye on Aniva Bay, building an onshore processing facility (OPF), building an oil export terminal (OET), and building a liquid natural gas (LNG) plant and terminal.

The two fields contain an estimated 1.2 billion barrels (190,000,000 m³) of crude oil and 500 billion cubic meters (18 trillion cubic feet) of natural gas, 9.6 million tonnes of liquefied natural gas a year and about 180,000 barrels per day (29,000 m³/d) of oil will be produced.

[edit] LNG

This will be the first ever LNG plant built in Russia. Shell estimates that the LNG plant will have the ability to meet eight percent of the world’s current LNG demand, 9.6 million tonnes of LNG per year, at the new plant, which will be in Prigorodnoye (Prigorodnoe) on Aniva Bay on the southern tip of Sakhalin, 13 kilometers east of Korsakov, on 4.9 km². Two trains will have an annual capacity of 4.8 million tones each.

The LNG plant will have two LNG storage tanks of 100,000 cubic meter net capacity each and LNG will be exported via an 805-metre jetty in Aniva Bay. The jetty will have two loading arms and one boil-off gas return arm, with ship loading expected to take between six and sixteen hours depending on the size of the cargo.

An important step for the project has been to have LNG contracts in place with major customers. The first shipments of LNG are projected to be summer of 2007.

So far Sakhalin Energy has signed up three LNG agreements:

  • Tokyo Gas : 1.1 million t/year - 24 years (May 2003)
  • Tokyo Electric Power Company: 1.5 million t/year - 22 years (May 2003)
  • Kyushu Electric Power Company: 0.5 million t/year - 21 years (2003).

The LNG plant construction consortium is awarded to two Russian companies, OAO Nipigaspererabothka (Nipigas) and the KhimEnergo consortium, together with two Japanese companies Chiyoda Corporation and Toyo Engineering.

[edit] Oil export terminal

Located on Aniva Bay, 500 meters east of the LNG plant. Total storage capacity will be 1.2 million barrels (190,000 m³) in two tanks (about six days pipeline throughput). Subsea pipeline to a tanker-loading unit (TLU), which is located about five kilometers offshore in the bay can load oil at a rate of 50,000 barrels per hour (8,000 m³/h).

[edit] Infrastructure upgrade projects

Sakhalin II will create permanent work for up to 2,400 people and jobs for an estimated 10,500 more during the construction period. Together with Sakhalin-I, unemployment should remain low and island improvements greatly expanded. To complete the plants and pipeline, Sakhalin Energy will spend $300 million (US) to upgrade the islands infrastructure: roads, bridges, waste management sites, airports (including one at Nogliki), railways and ports, at more than 50 construction sites.

  • Sakhalin Western Marine Port: To allow for the inbound receipt of Phase 2 construction materials including pipeline and Onshore Processing Facility cargo, the Port of Kholmsk, on the southwest part of the island, has been upgraded. Work includes: dredging works, quayside works, installation of rail sidings, access roads, 4 x 20 t and 1 x 32 t gantry cranes erected, Berth 5 has been refurbished, final works at the port including office and warehouse upgrades are currently ongoing.
  • Federal Roads and Bridges: 39 bridges & bridge approaches, bridge and culvert construction, 16 km of federal roads are being reconstructed, and a further 12 km of federal carriageway is being asphalted.

[edit] Environmental impacts

The project has been dogged by environmental and social criticism and opposition from numerous environmental groups including Sakhalin Environment Watch, World Wide Fund for Nature, Friends of the Earth, Bankwatch, Pacific Environment, IUCN, as well as from residents of Sakhalin and independent scientists.

One key concern is that the project, the NGO's argue referring to an International Scientific Review Panel (ISRP) report on Sakhalin II project impacts to the critically endangered Western Gray Whale, will push the world's last 100 or so western pacific grey whales into extinction.

Other concerns are that the project will destroy the marine environment, threaten the livelihood of tens of thousands of fishermen, destroy the key salmon fishing area off the island by dumping one million tons of dredging spoil waste into the sea, and finally imply a permanent threat of a large oil spill in the Okhotsk and Japanese seas.[1]

The key NGOs demands in this regard are:

  • Pipeline crossings across all spawning rivers and streams on Sakhalin Island must be made with a bridge over the river, on specially designed suspension systems, to avoid damage to the streambed and water channels.
  • The new proposed platform for the Piltun-Astokhskoye field for Sakhalin-2 Phase 2 must be moved at least 12 nautical miles from shore in order to ensure that the platform does not harm the habitat of the critically endangered western grey whale.
  • Discharge of any wastes into Aniva Bay is categorically impermissible.
  • Shell, Mitsubishi, Mitsui and Gazprom, must take full financial liability for any oil spill within Russia (including Aniva Bay and the La Peruse strait) from tankers and compensate all expenses for liquidating and cleaning polluted areas, and pay compensation to injured people. The international financial institutions should financially guarantee that the clean up funding and compensation is available after the accident.[1]

Criticism has also come from other sides. In 2003, the European Bank for Reconstruction and Development, a potential financier of the project deemed Sakhalin-II 'unfit for purpose' due to environmental concerns. The project, many argued, was in direct violation of the Equator Principles, a set of voluntarily guidelines adopted by the world’s leading banks, and a number of Equator Principles banks have already indicated that they will not fund Sakhalin II.

Shell has responded to these concerns saying that the project meets lenders' policies and that environmental and that social issues have been met.

[edit] Recent developments

In 2005, Shell agreed to swap 25% of Sakhalin-II to Gazprom, in exchange for 50% of a natural gas field in the Russian Arctic, plus cash. Several days after the deal was signed, Shell doubled its cost estimates for Sakhalin-II to $20 billion. This move is reported to have highly angered Gazprom and the Russian government, since this implied lower potential profits for them.

On September 18, 2006, Russian regulators withdrew an environmental permit for Sakhalin-II, citing damage to salmon streams. This was widely interpreted as a move by the Russian government to force a renegotiation of the Sakhalin-II deal.[2]
