Discovery off East Asia could transform South Korea's energy dependence and boost the country's geopolitics
One of the discovery of great economic and energy relevance was made in South Korea em 2024, attracting worldwide attention. According to reports from Bloomberg Línea and Exame, the country identified one of the largest potential oil and natural gas reserves in Asia. The preliminary estimate points to up to 14 billion barrels of recoverable oil, the result of studies conducted under authorization from the then president Yoon Suk Yeol.
The detail that sparked global interest was the presence of Brazilian geologist Vitor Abreu, native of Rio Grande do Sul, who participated directly in the technical analysis of the project. According to Abreu, there is about a 20% chance if the field proves productive, a rate considered standard in the hydrocarbon exploration sector.
Technical discovery and detailed geological studies
The discovery comes from seismic studies starting in 2023, led by international experts and supervised by the Ministry of Trade, Industry and Energy of South Korea. The surveys indicated hydrocarbon-rich sedimentary layers at a depth of more than two thousand meters on the east coast, a region still little explored.

According to Bloomberg Line (2024), the first drilling tests began in mid 2024 and will continue until the early 2025, with support from international engineering companies. Abreu highlighted that the place presents geological features similar to producing fields in the Gulf of Mexico, which increases technical interest despite the financial and environmental challenges.
Energy and economic impacts of the reserve
The estimated potential — of 14 billion barrels - It's enough to supply South Korea for up to four years, according to calculations by the portal Metropolises (2024). In the case of natural gas, reserves can guarantee energy autonomy of up to 29 years, which would drastically reduce dependence on imports.
The discovery comes at a strategic time, as the Asian country imports almost 100% of the oil it consumes, according to data from U.S. Energy Information Administration (EIA). Thus, the government sees this as an opportunity a milestone to redefine its energy policy e expand its geopolitical influence in the region.
Political challenges and financial resistance
Despite the optimism, the project faces political and economic barriers. Deepwater drilling requires high public investments e operating costs above the global average. Opposition parliamentarians warn that the financial risk is high, especially because the Australian company Woodside Energy, after 15 years of research, abandoned the project in 2016 due to economic unfeasibility.
Even so, Yoon Suk-yeol publicly defended the program as strategic for national energy sovereignty. Meanwhile, technicians seek to balance economic growth and environmental responsibility, as South Korea maintains its commitment to carbon neutrality by 2050.
Planning and future of energy exploration
Currently, the South Korean government is focusing its efforts on environmental impact studies and technical feasibility analyses. Operations are being supervised by state agencies in partnership with academic institutions and private energy companies. The goal is define clear rules for concession and supervision before the start of commercial exploitation.
Authorities claim that exploratory drilling will continue until the first half of 2025, when the conclusive report on the production potential will be presented. Case confirmed, the deposit can transform South Korea's role in global energy market, expanding its independence and strengthening its exports.
Discovery in a global context
The announcement of the reserve on the South Korean coast reinforces the global trend of reopening deepwater exploration fronts, similar to what happens in Guyana, Brazil and Namibia. According to Bloomberg Line (2024), these new areas can redefine the world energy map in the coming decades.
Experts say the discovery places the country in a strategic position to negotiate with major industry players, such as Saudi Arabia and the United States, balancing forces in the sector. Furthermore, the presence of a Brazilian in the geological team highlights the growing role of Latin American experts in large-scale international projects.
What does the future hold for South Korea?
Energy and foreign policy analysts assess that confirmation of the oil field could redefine the Asian economic landscape. However, prosperity will depend on transparent management, environmental responsibility and geopolitical balance.
Meanwhile, the work continues at a fast pace, and the world is watching closely for the next steps. If the exploration is successful, South Korea could emerge as a new energy powerhouse. But if it fails, the financial and environmental cost could be high.
What do you think: Should South Korea move quickly into exploration to ensure self-sufficiency or prioritize a more sustainable energy transition?
