Rystad Energy estimates South America could lift daily oil output by 2.1 million barrels by 2035 if crude trades around $100 a barrel. The modelling assumes new projects move swiftly and that the region’s infrastructure can handle the surge. Adding that volume would represent a sizable share of global supply, reshaping trade flows. Such growth would also attract foreign investment into offshore drilling and pipeline upgrades.

Brazil, Guyana and Suriname together could contribute roughly one million barrels per day over the next decade, while Venezuela might add about 910,000 bpd provided fiscal reforms and sanctions relief materialise, Rystad Energy notes. Argentina’s Vaca Muerta basin is also expected to accelerate development, promising output that could outpace earlier forecasts. The combined output could push the region’s export share past 12 percent of global oil trade.

An extra 2.1 million bpd would ease current market tightness, pressuring prices downward and giving refiners more feedstock flexibility. Investors will gauge the pace of project approvals and the political climate in Venezuela as decisive factors. Energy firms are already lining up financing, signaling confidence that the projected capacity will materialise. The projection signals that South America could become a more prominent oil exporter within a decade.
