Resource Potential in the Arctic

The Arctic is estimated to hold a significant share of the world’s undiscovered oil and gas resources. A widely cited assessment by the U.S. Geological Survey (USGS) suggests that the region may contain around 13% of the world’s undiscovered oil and 30% of its undiscovered natural gas, much of it located offshore.

In total, this corresponds to an estimated 412 billion barrels of oil equivalent, highlighting the Arctic’s potential importance in global energy supply.

Regional Distribution of Resources

Arctic resources are not evenly distributed. Approximately three-quarters of the undiscovered resources are expected to be natural gas and natural gas liquids (NGL), with large concentrations in Russia’s Arctic regions, particularly the West Siberian Basin and the East Barents Basin.

In contrast, the North American Arctic, including Alaska and areas north of Canada, is believed to hold a larger share of the region’s undiscovered oil resources. Key areas include:

• Arctic Alaska, with significant estimated oil reserves
• The Amerasia Basin north of Canada
• The East Greenland Rift Basin

Together, these regions account for a substantial portion of the Arctic’s remaining oil potential.

Recent Developments and Exploration

Exploration activity in parts of the Arctic has confirmed the presence of commercially viable oil and gas fields. In the Barents Sea, for example, discoveries such as the Skrugard (Johan Castberg) field and the Goliat field have demonstrated ongoing interest in Arctic energy development.

At the same time, exploration in other areas, such as offshore Greenland, has so far yielded limited results, highlighting the uncertainty and complexity of Arctic resource exploration.

Technical and Environmental Challenges

Despite its resource potential, Arctic oil and gas development faces significant challenges. Harsh environmental conditions, including extreme cold, sea ice, and remote locations, require specialised technologies and infrastructure.

Climate change is also affecting operating conditions, altering ice patterns and placing new demands on engineering, transportation, and safety systems such as pipelines and offshore platforms.

Environmental considerations are particularly important in the Arctic. The region’s ecosystems are fragile, and oil and gas activities must meet strict standards to minimise impacts on wildlife and habitats.

Political and Economic Factors

Development in the Arctic is also influenced by geopolitical and economic factors. Disputes over maritime boundaries and resource ownership have historically delayed exploration in some regions, although agreements, such as the Norway–Russia maritime delimitation in the Barents Sea (2011), have enabled new activity.

At the same time, Arctic projects are often costly and complex, requiring long-term investment. Their economic viability depends heavily on global energy prices, technological advances, and competition from other energy sources.

Energy Transition and Future Outlook

In recent years, the global energy landscape has shifted significantly. Growing attention to climate change, renewable energy, and decarbonisation is influencing decisions about future oil and gas development.

While Arctic resources remain substantial, many projects face increasing scrutiny due to:

• environmental risks
• high development costs
• global efforts to reduce fossil fuel dependence

As a result, the future of Arctic oil and gas development is uncertain. Some regions may continue to see targeted development, while others may remain largely untapped.

Looking Ahead

Although the Arctic holds considerable energy resources, their development is likely to remain gradual and selective. Balancing economic opportunities, environmental protection, and Indigenous rights will be central to any future activity in the region.

Predicting the scale and timing of future Arctic oil production remains challenging, as it will depend on a complex combination of technological, political, and environmental factors.
