Oil Majors Bet Big on Uruguay Offshore to Mirror Namibia Finds
A consortium of global oil majors is committing capital to Uruguay's unproven deepwater blocks, betting that geological links to Namibia will yield a billion-barrel province free from Middle Eastern chokepoints.
APA Corp is preparing to spud the first exploration well in Uruguay’s deepwater later this year or early in 2027, marking the start of a high-stakes drilling campaign that has attracted nearly every Western oil major.
Shell, Chevron, Eni, QatarEnergy, and Argentina’s YPF have secured rights across all seven of Uruguay’s recently contracted offshore blocks. They are hunting for a new billion-barrel oil province, spurred by recent massive discoveries across the South Atlantic in Namibia.
The geological theory driving this investment is that South America and Africa were once joined, suggesting Uruguay's subsea formations mirror Namibia's prolific basins. However, the risk remains high. Uruguay has only seen three previous offshore wells, all of which came up dry.
The most aggressive projection comes from YPF. The Argentine company’s chief executive, Horacio Marín, said this week that the OFF-5 block could eclipse Argentina's massive Vaca Muerta shale play. “This could be much bigger than Vaca Muerta, it could yield millions and millions of barrels of production,” Marín said.
Italy’s Eni has already moved to shoulder that risk, signing an agreement late last year to acquire a 50% stake and operatorship of OFF-5 from YPF. The transaction is awaiting regulatory approval in Uruguay. “Block OFF-5 represents a highly prospective area that further strengthens Eni’s exploration portfolio,” the company said in November.
Other majors are rapidly consolidating positions. QatarEnergy recently acquired interests in three blocks—OFF-2, OFF-4, and OFF-7—from BG International, a Shell subsidiary. Chevron and QatarEnergy have also farmed into multiple blocks adjacent to Sintana Energy’s OFF-3 block.
For smaller explorers, this major-led rush provides crucial validation. Sintana completed its first season of 3D seismic acquisition on the OFF-1 block this month and is farming out OFF-3. “The ongoing and increasing level of investment and activity by major international oil companies in Uruguay is a strong endorsement of the prospectivity of the Company's Uruguayan assets,” Sintana said.
The financial appeal extends beyond geology. A successful offshore strike would grant operators direct access to Atlantic shipping lanes, providing Europe and Asia with crude that bypasses the Strait of Hormuz and other volatile chokepoints.
Any production is at least a decade away. Operators must first navigate deepwater drilling challenges and a total lack of existing infrastructure. The immediate focus for markets will be on the outcome of APA’s inaugural well, which will determine if Uruguay's offshore potential is geological fact or merely speculative theory.
