Argentina's LNG Dream Gets Two Heavyweight Backers

Eni and XRG each take 32% stakes in three Vaca Muerta blocks, anchoring a floating LNG project aimed at 12 million tons a year.

Eni and XRG have each acquired 32 percent stakes in three upstream blocks in Argentina's Vaca Muerta shale formation, a deal announced June 29 that aims to supply a floating liquefied natural gas export project with capacity for 12 million metric tons annually. YPF will retain the remaining 36 percent stake, though regulatory approvals are still pending.

The agreement covers three blocks: Meseta Buena Esperanza, Aguada Villanueva, and Las Tacanas. Their reserves are intended to feed the Argentina LNG project across two dedicated floating units. Guido Brusco, Eni's chief operating officer for global natural resources, said the partnership strengthens the company's ability to convert large-scale gas resources into competitive LNG for buyers seeking reliable, diversified supply.

For Argentina, the arrangement marks a step toward monetizing one of the world's largest shale formations through two internationally established partners. Floating LNG technology shortens the path to first exports compared with onshore liquefaction plants, since it avoids many of the permitting and construction delays tied to fixed infrastructure. That could matter for buyers in Europe and Asia, who are looking to diversify supply as the global LNG market remains tight.

Other observers note that large energy projects of this scale often carry execution risk, particularly where regulatory clearance and financing milestones must align before construction begins. Analysts have pointed to similar floating LNG ventures elsewhere that faced delays despite strong initial backing, suggesting Argentina's timeline could shift depending on how quickly approvals proceed.

Beyond the upstream blocks, the project is expected to draw further investment into Patagonia's energy infrastructure and labor markets if it advances as planned. Whether Vaca Muerta becomes a major Atlantic Basin supplier will likely depend on how smoothly the partners navigate the remaining regulatory and commercial steps. The outcome could shape Argentina's position in global energy trade for years to come.
