A newly released report has positioned Greenland’s Jameson Land basin as one of the most significant undeveloped onshore oil plays in the world. An independent prospective resource evaluation by Sproule ERCE estimates the basin contains about 13.03 billion barrels (P10, gross unrisked) of recoverable oil. This estimate places the basin among major frontier discoveries, marking a pivotal moment for Greenland’s energy outlook.
The basin spans roughly 2 million acres in East Greenland. It is a structurally complex, underexplored region with minimal drilling history, but it has gained attention due to advancements in subsurface mapping, favorable geological modeling and growing commercial interest. The Sproule report identifies 58 prospects and leads, making it one of the most densely prospective areas in the Arctic for hydrocarbon development.
If accurate, the recoverable oil volume would rank the Jameson Land basin among the 15 largest undeveloped oil accumulations worldwide. In an era increasingly shaped by energy diversification and supply security, such figures are drawing investment interest, particularly from firms evaluating the long-term viability of frontier regions.
The resource estimate remains unrisked, meaning actual recoverability will depend on exploration, appraisal drilling and future infrastructure development. Still, the 13 billion-barrel estimate is substantial enough to direct international focus toward East Greenland.
Geological fundamentals: why the basin is considered world-class
The technical case for Jameson Land’s potential rests on several favorable geological features. The area contains multi-play systems with stacked reservoirs, thick sedimentary deposits and a mix of structural and stratigraphic traps. These traits support the presence of large, undrilled hydrocarbon systems that have remained sealed since formation.
The basin’s sedimentary sequences resemble those in proven hydrocarbon-producing regions in North America and Europe. Jameson Land shares structural similarities with rift basins like the North Sea and parts of Western Canada. The combination of rift tectonics and sedimentary fill has historically produced reliable petroleum systems under the right thermal and trap conditions.
Sproule’s evaluation noted effective source rock intervals with enough maturity to generate oil. Regional uplift and erosion, while geologically complex, have helped preserve trap integrity and migration pathways. Seismic and gravity data have also confirmed structural closures at multiple depths, increasing the likelihood of encountering hydrocarbons in different zones.
The basin’s stacked potential appeals to operators seeking scale through multi-zone drilling. Even partial success across the 58 mapped prospects could support long-term phased development.
Operational roadmap: joint venture, drilling plans and commercial context
The commercial structure behind exploration in Jameson Land has taken shape. White Flame Energy A/S, a subsidiary of 80 Mile PLC, holds a 30 percent working interest. It has entered a farm-out agreement with March GL Company, a private exploration firm that can earn up to 70 percent interest through a staged work program.
Two exploration wells are planned for the second half of 2026. These will test structural closures at depths over 3,500 meters, targeting reservoirs identified through 2D seismic and gravity surveys. Results from these wells will influence future capital allocation and development strategy.
The joint venture model fits the profile of frontier Arctic exploration. It enables smaller-cap firms to combine technical expertise while sharing financial and operational risk. March GL’s backing by institutional energy funds has been interpreted as a sign of confidence in the basin’s resource quality.
Timing is another factor. While several major companies are exiting Arctic exploration due to environmental targets or shareholder pressure, smaller and privately held firms are stepping into regions previously dominated by large corporations. Jameson Land is an example of how the risk-reward calculus is shifting across the exploration landscape.
Logistics, regulatory and environmental considerations in Arctic exploration
East Greenland poses logistical and regulatory challenges that extend beyond geological factors. The region lacks major infrastructure. Transportation and support systems must either be developed from scratch or significantly upgraded.
Greenland’s government has implemented a licensing system that seeks to balance commercial interest with environmental protection. Operators must complete environmental impact assessments and comply with requirements from the Mineral Resources Authority. Community consultation is also mandated as part of project approvals.
Environmental conditions further complicate operations. Drilling windows are limited by Arctic weather, permafrost and seasonal wildlife patterns. Sea ice and remote terrain restrict equipment mobilization and can constrain project timelines.
However, recent improvements in mobile drilling units, ice-capable transport and low-impact surface technologies make Arctic operations more feasible than in the past. Directional drilling and modular infrastructure offer ways to reduce environmental disruption.
As Greenland considers its broader resource strategy, the Jameson Land basin may set the precedent for future development in sensitive environments.
Jameson Land’s emergence contributes to a changing conversation around Arctic exploration. While political and environmental considerations remain central, the sheer scale of potential oil resources in this basin could influence decisions from both governments and investors.
For Greenland, the project aligns with long-term economic goals focused on resource-based development. While production is still years away, successful exploration could bring fiscal revenues, long-term jobs and more influence over its economic future.
