Russia Claims Seismically Defined Discovery of 511 Billion-Barrels of Oil in Antarctica

   

     Russia claims to have discovered a very large oil accumulation in an area of Antarctica controlled by the U.K. Research missions under the Weddell Sea assess the discovery at 511 billion barrels, which makes it rival Venezuela’s untapped Orinoco Sand Belt as the largest oil accumulation in the world. Resource extraction is prohibited in the territory by the 1959 Antarctic Treaty. It would also be very expensive to set up operations and facilities. Seismic methods were used to identify the resource. Russia has been accused of prospecting under the guise of research, but also insists it is in compliance with the treaty.

     The remote and environmentally sensitive continent may in the future have issues with resource development, but for now, it seems likely it will remain off limits. The U.K. authority of the territory in question is disputed by Chile and Argentina, but the whole continent has been limited to peaceful and scientific expeditions. Military and mining sites are prohibited. Russia may be trying to stretch norms with the provocative surveying. Apparently, the actual results have not been published so no one knows the details or even if the assessment is plausible.

     Russia has five research stations on Antarctica and has conducted many seismic surveys as part of that research. The discovery was outlined in evidence presented to the UK Parliament’s Environment Audit Committee (EAC) in mid-2024. Antarctic “competition” is predicted to heat up in the future. Strategic confrontation and legal ambiguity may become an issue in the future. China is building its fifth Antarctic research station. Several countries have contested territories there that are not recognized by the U.S., Russia, and other countries. China has blocked the expansion of some off-limits reserves. Antarctic competition is already happening.

     As noted, there is skepticism about the Russian assessment, both from the possibility of the source of the news being biased, and from the evidence being based on seismic alone.

     Brandon J. Weichert, writing for The National Interest, stated:

“The United States must take strong, proactive measures to secure its position in the Antarctic and work to deny the Chinese and Russians greater access to these massive, untapped resources.”

     I am not sure if I agree totally, but I definitely don’t want Russia, China, or really anyone else to be drilling for oil on the continent. It would be nice to see the data and seismic interpretations.
