Sakhalin Chayvo Field Orlan Platform

Our Arctic presence

ExxonMobil, with the industry's longest history operating in Arctic conditions in both Arctic and sub-Arctic locations, is best positioned to unlock the region's vast energy potential.


  • Sakhalin-1 is one of the largest oil and gas projects in Russia. 
  • While sub-Arctic, its location in the Sea of Okhotsk experiences more dynamic ice conditions than many offshore areas north of the Arctic Circle.
  • Exxon Neftegas Limited, the operator of the Sakhalin-1 consortium, produces oil and gas off the northeast coast of Sakhalin Island in the Russian Far East.
  • The Sakhalin-1 project includes three reservoirs: Chayvo, Odoptu and Arkutun-Dagi.
  • Advanced technologies are integrated into drilling programs, facility design and transportation systems to improve efficiency and ensure environmental protection.

Chayvo field

  • The Chayvo field development included using the onshore Yastreb rig and the offshore Orlan platform.
  • The Orlan platform is built to withstand earthquakes and difficult sea ice conditions offshore Sakhalin Island.
  • Chayvo production began in 2005 and development continues with additional drilling activities underway.
  • All Sakhalin-1 produced oil and gas is pipelined to the Chayvo Onshore Processing Facility where it is processed and stabilized for export.
  • The world’s longest extended reach well was drilled at Chayvo.

Odoptu field

  • The second phase of Sakhalin-1 included the development of the Odoptu reservoir.
  • The use of the Yastreb drill rig enabled access to the offshore Odoptu reservoir from an onshore location.
  • Odoptu production began in 2010.
  • A flowline transports the Odoptu field’s oil and gas to the Chayvo Onshore Processing Facility.

Arkutun-Dagi field

  • The next phase of the Sakhalin-1 includes the development of the Arkutun-Dagi reservoir.
  • The Berkut platform is an offshore, ice-resistant platform that is the largest oil and gas production platform in Russia.
  • Production from the Berkut platform commenced in January 2015.
  • Harsh sub-Arctic environment of the Sea of Okhotsk with winter temperatures dropping down to 44oC below zero, waves reaching 18 meters and almost 2 meter ice field in winter season.
  • The topsides of the platform weigh 42,000 tonnes and were the heaviest integrated topsides ever floated.

Dekastri terminal

  • The De-Kastri export terminal incorporates the world’s largest single point mooring facility.
  • The fully automated tower is located nearly six kilometers offshore.
  • The terminal has safely transported more than 60 million tonnes of stabilized crude oil without incident.


  • ExxonMobil has been active in Alaska for more than 60 years.
  • We are the largest holder of discovered gas resources in the North Slope and the largest interest owner of the Prudhoe Bay unit.
  • Our technology has increased recoverable reserves in the Prudhoe Bay unit by approximately 30%.
  • We are contributing to the next chapter of Alaska’s energy development through the Alaska LNG project.

Point Thomson

  • The Point Thomson natural gas condensate project is under construction on Alaska’s North Slope.
  • Production started up in 2016.
  • The project uses proven extended reach drilling technology to access offshore resources from onshore facilities.
  • Data collected from extensive field studies is used to minimize impacts on the environment and local wildlife.

Norman Wells

  • Norman Wells marked the start of the quest for arctic oil and gas.
  • Discovered in 1920, the reservoir has been continuously producing for more than 90 years.
  • The reservoir extends below the Mackenzie River which is covered by several feet of ice for most of the year.
  • To access the reservoir, we developed the first arctic use of artificial gravel islands and extended reach drilling.
  • Due to the extreme temperatures, the Norman Wells project led the development and use of off-site modular construction.

Grand Banks - Hibernia

  • Hibernia was the world’s first iceberg-resistant gravity-based structure and remains Canada’s largest offshore platform.
  • The Hibernia platform is able to withstand contact with a six-million ton iceberg.
  • Our robust iceberg management system uses satellite, aerial and marine reconnaissance to detect icebergs and safely alter their trajectory away from the platform.
  • ExxonMobil’s advanced oil recovery technology has been used to support both water and gas injection at Hibernia, with the potential to recover as much as 60 percent of the hydrocarbon resource.

Grand Banks - Hebron

  • The Hebron field will be developed using a stand-alone concrete gravity-based structure built almost entirely in Newfoundland and Labrador.
  • Production is expected to begin in 2017.

Beaufort Sea

  • Imperial is the operator of a Joint Venture with BP and ExxonMobil Canada in the Beaufort Sea for exploration licenses located more than 120 kilometers off the coast of Canada’s Northwest Territories.
  • Currently, Imperial is evaluating exploration technology alternatives and working with Indigenous and Northern Affairs Canada on exploration license tenure.

Kara Sea

  • ExxonMobil and Rosneft are exploring in the Kara Sea in license areas that include more than 125,000 square kilometers, which is equivalent to all the leases in the Gulf of Mexico combined.
  • In 2012 and 2013 studies were conducted mapping hydrocarbon deposits as well as collecting data about the seabed, wave patterns and wildlife.
  • In June 2013, ExxonMobil and Rosneft established the Arctic Research & Design Center to provide research, development and technical services for arctic oil and gas development, with near-term focus on the Kara Sea.

North Sea

  • We operate four offshore projects and hold interest in 20 more in the Norwegian sector of the North Sea.
  • Our experience in the North Sea led to the development of solutions for the protection of pipelines, seabed facilities and subsea tiebacks in ice-filled water.

Russian Arctic Shelf

  • In February 2013, ExxonMobil and Rosneft announced plans to increase the scope of their strategic cooperation by adding seven new blocks in the Russian Arctic.
  • In 2014, geophysical and environmental studies began in sections of the Chukchi Sea, Laptev Sea and northern Kara Sea, in license areas spanning 600,000 square kilometers.
