A discovery off Brazil’s Atlantic coast could prove to be the world’s third-largest oil field, the director of Brazil’s National Oil Agency said.
The Carioca field in the Santos Basin off the coast of Sao Paulo state has estimated reserves of 33 billion barrels, Haroldo Lima said on Monday.
“It could be the world’s biggest discovery in the past 30 years,” he said.
Brazil’s state oil company, Petrobras, which controls 45 percent of the field, said in a statement that the exact size of the find would be announced in the coming days after further studies were done.
PROFITABLE?
Petrobras engineers said they could not yet say whether extraction would be profitable.
Nevertheless, Petrobras stock rose 5.6 percent, closing at 82.97 reals (US$49.18), after surging as high as 7.7 percent in Sao Paulo.
Lima said that while his information was from Petrobras, it was “unofficial.” Brazilian Energy Minister Edison Labao advised waiting for the official disclosure.
If Lima’s estimates are correct, however, Carioca would rank behind Saudi Arabia’s Ghawar oil field and Kuwait’s Burgan field in size.
Carioca lies about 5,000m deep under a thick layer of salt. The remaining interests in the field are held by British Gas at 30 percent and Spain’s Repsol at 25 percent.
FOUR TIMES LARGER
If Lima’s announcement proves correct, Carioca would be at least four times larger that the Tupi field discovered in November, also in the Santos Basin.
That field, of which Petrobras holds 65 percent, is believed to have oil and gas reserves of 5 billion to 8 billion barrels. Extraction could begin at the earliest there in four or five years, experts said.
Petrobras’ production is 1.9 million barrels per day, while its estimated reserves are 13 billion barrels.
Brazil ranks 17th among the countries with the largest oil reserves.
Nvidia Corp yesterday unveiled its new high-speed interconnect technology, NVLink Fusion, with Taiwanese application-specific IC (ASIC) designers Alchip Technologies Ltd (世芯) and MediaTek Inc (聯發科) among the first to adopt the technology to help build semi-custom artificial intelligence (AI) infrastructure for hyperscalers. Nvidia has opened its technology to outside users, as hyperscalers and cloud service providers are building their own cost-effective AI chips, or accelerators, used in AI servers by leveraging ASIC firms’ designing capabilities to reduce their dependence on Nvidia. Previously, NVLink technology was only available for Nvidia’s own AI platform. “NVLink Fusion opens Nvidia’s AI platform and rich ecosystem for
WARNING: From Jan. 1 last year to the end of last month, 89 Taiwanese have gone missing or been detained in China, the MAC said, urging people to carefully consider travel to China Lax enforcement had made virtually moot regulations banning civil servants from making unauthorized visits to China, the Control Yuan said yesterday.

CAUSE AND EFFECT: China’s policies prompted the US to increase its presence in the Indo-Pacific, and Beijing should consider if this outcome is in its best interests, Lai said China has been escalating its military and political pressure on Taiwan for many years, but should reflect on this strategy and think about what is really in its best interest, President William Lai (賴清德) said. Lai made the remark in a YouTube interview with Mindi World News that was broadcast on Saturday, ahead of the first anniversary of his presidential inauguration tomorrow. The US has clearly stated that China is its biggest challenge and threat, with US President Donald Trump and US Secretary of Defense Pete Hegseth repeatedly saying that the US should increase its forces in the Indo-Pacific region
