Eni Locks In Uruguay Offshore Stake as South American Upstream Push Widens
Italy's Eni has secured a 50% operating stake in Uruguay's OFF-5 deepwater block, adding Atlantic frontier exploration to a rapidly expanding South American portfolio.
Eni SpA has signed an agreement with YPF's subsidiary and Uruguay's state energy company ANCAP to acquire a 50% operating stake in the OFF-5 exploration license off Uruguay's Atlantic coast. The deal, reported by Rigzone, formalizes an entry into one of the least-drilled deepwater margins in the Western Hemisphere.4
Uruguay has logged only a handful of exploration wells in its offshore history, leaving the resource potential largely uncharacterized. Analysts at Oilprice.com have drawn comparisons to the South Atlantic conjugate margin offshore Namibia, where major discoveries reshaped exploration priorities in recent years, though any analogy carries significant uncertainty given the scant drilling record.3
The Uruguay move is one piece of a broader southward push by Eni. In late June (2026-06-29), the Italian major and Abu Dhabi's XRG entered three Vaca Muerta blocks in Argentina, with production earmarked to underpin an LNG export project. The Argentina LNG joint development agreement, announced on February 12 (2026-02-12), targets two floating liquefaction trains with combined nameplate capacity of 12 million metric tons per annum. Operationally, the OFF-5 acquisition and the Vaca Muerta entry involve the same regional partner: YPF.2,4
The more politically charged thread in Eni's South American activity runs through Venezuela. On September 4 (2026-09-04), Eni finalized a 25-year agreement with PdVSA to relaunch development at the Junín-5 heavy oilfield in the Orinoco Belt. The field holds 35 billion barrels of certified oil in place but produces around 12,000 barrels per day currently — a gap that defines both the opportunity and the execution risk.7
Eni already has a substantial Venezuelan footprint through the Perla gas field, which accounts for roughly 35% of Venezuela's domestic gas demand and generated the bulk of Eni's 64,000 barrels of oil equivalent per day in the country last year. Junín-5 would represent a far larger bet: heavy oil development in the Orinoco requires capital-intensive upgrading infrastructure, and Venezuela's above-ground risks — sanctions history, PdVSA's operational track record, political unpredictability — have deterred sustained investment for decades.7
Venezuela holds an estimated 300 billion barrels of oil in place, more than Saudi Arabia, yet produces around 1 million barrels per day — less than Libya. The Eni-PdVSA deal lands alongside a cluster of foreign agreements being finalized simultaneously. As of late August (2026-08-31), Chevron, India's ONGC, GE Vernova and GeoPark were each preparing to sign final energy agreements in Venezuela, Reuters reported. ONGC is targeting a tenfold increase in output at the San Cristobal field with roughly $200 million in investment.1,5
Chevron's agreements announced on September 4 (2026-09-04) are larger in scale. The company announced new joint venture arrangements involving over $7 billion in investment over five years, with a stated objective of more than doubling its Venezuelan production to approximately 600,000 barrels per day — an increase of more than 300,000 barrels per day, or about a quarter of Venezuela's current total output. Those deals follow talks facilitated by the Trump administration.7,6
Separate from the company-level agreements, a U.S.-Venezuela pact announced the week of August 24 (2026-08-24) covers stakes in 17 oilfields carrying about 64 billion barrels of proved reserves. An earlier proposal had involved roughly 90 billion barrels. Foreign Policy reported on September 4 (2026-09-04) that Venezuelan critics have decried the arrangement as opaque and colonialist, a domestic political complication that companies with Venezuelan exposure will need to monitor.5,6
ICE Brent crude front-month was trading at $106.24 per barrel as of September 14 (2026-09-14). At that level, the economics of heavy Orinoco upgrading remain tight relative to lighter barrels, and the upgrade infrastructure required to monetize Junín-5 at scale does not yet exist in the volumes the resource would demand. Whether PdVSA can sustain the operational partnership through a 25-year horizon — across multiple U.S. administrations and Venezuelan political cycles — is a different question from whether Eni can drill a promising offshore block in Uruguay.
The two strategies carry different risk profiles. OFF-5 is a frontier exploration play where the primary uncertainty is geological. Junín-5 is a known resource where the uncertainty is almost entirely about above-ground conditions, counterparty reliability and the durability of U.S. sanctions policy toward Caracas. How Eni manages those two exposures simultaneously, from Rome, will be worth tracking as the Venezuelan agreements move from signing to implementation.7,4
