Uruguay Offshore Oil Exploration: 2026 Drilling Begins

• Uruguay offshore oil exploration is entering its first drilling campaign in a decade, with APA Corp expected to spud a well in late 2026 or early 2027.
• Six international majors — Shell, Chevron, Eni, APA, QatarEnergy and YPF — now hold interests across all seven of Uruguay’s contracted offshore blocks.
• YPF chief executive Horacio Marín says Block OFF-5 could ultimately outproduce Argentina’s Vaca Muerta shale play.
• Eni is seeking approval to acquire a 50% stake and operatorship of Block OFF-5 from YPF.
• Geological parallels with Namibia’s offshore discoveries are driving renewed interest in the South Atlantic margin.

Uruguay Offshore Oil Exploration Enters Its First Real Test

Uruguay offshore oil exploration has moved from paper acreage to committed drilling for the first time in a decade. APA Corp is lined up to spud the country’s fourth-ever offshore well in late 2026 or early 2027, with YPF following in 2027-2028. Uruguay’s three prior wells, drilled years ago, all came up dry — but this campaign carries a different weight of capital behind it.

The renewed interest traces back to Namibia. Explorers view Uruguay’s continental margin as a geological match to discoveries that reshaped expectations for the wider South Atlantic. Oilprice.com reports that Shell, Chevron, Eni, APA, QatarEnergy and YPF have all acquired rights across Uruguay’s seven offshore blocks in recent years.

Why Majors Are Betting on Block OFF-5

Block OFF-5 has emerged as the campaign’s centrepiece. YPF chief executive Horacio Marín has said the block could yield production volumes that eclipse Vaca Muerta, Argentina’s flagship shale play and a familiar reference point for readers tracking South America’s Vaca Muerta infrastructure build-out. Eni has moved to formalise its position, agreeing to acquire a 50% stake and operatorship in OFF-5 from YPF, a deal still pending Uruguayan regulatory sign-off.

QatarEnergy has taken a broader spread across the portfolio, acquiring stakes in blocks OFF-2, OFF-4 and OFF-7 from Shell subsidiary BG International. Chevron and QatarEnergy have also farmed into acreage adjacent to Sintana Energy’s OFF-3 block, where a first season of 3D seismic acquisition has just wrapped.

What Uruguay Offshore Oil Exploration Means for Storage and Export Infrastructure

Commercial production is years away, and Uruguay currently has none of the tank storage or export infrastructure a producing basin would need. But the geography is a genuine advantage: Atlantic-facing acreage with direct trade routes to Europe and Asia, without dependence on chokepoints like the Strait of Hormuz.

That combination is exactly why operators across Latin America are already investing in the region’s midstream backbone. OGSN’s ranking of Latin America’s leading tank terminals shows where that capacity is concentrated today.

Brazil offers the closest regional comparison for what Uruguay could eventually need on the LNG and product side, where regasification capacity has already doubled to meet growing import demand.

The Road Ahead for Uruguay Offshore Oil Exploration

The near-term test is straightforward: does APA’s well, and YPF’s following campaign, find hydrocarbons at all. Uruguay’s exploration history is short and largely unsuccessful, and deepwater drilling costs mean each well carries real financial risk regardless of how strong the Namibia comparison looks on paper. Uruguay offshore oil exploration will not resolve that uncertainty until drilling results start coming back from late 2026 onward.

What is already clear is the scale of major-company appetite. Six companies with global deepwater track records have committed capital to acreage with no proven commercial discovery to date. That level of pre-drill conviction is unusual, and it is the reason Uruguay offshore oil exploration is drawing comparisons to Namibia rather than being treated as a routine wildcat campaign.
