Eni and XRG Take 32% Stakes Each in Vaca Muerta Blocks Ahead of Argentina LNG FID
The upstream deal locks in feed gas supply for a 12 mtpa floating liquefaction project with a final investment decision scheduled for the second half of 2026.
Eni and Abu Dhabi's XRG each signed agreements on Tuesday (2026-07-01) to acquire 32% stakes in three upstream gas blocks in Argentina's Vaca Muerta shale, with state-controlled YPF retaining the remaining 36%. The sale and purchase agreements were confirmed by both companies, formalising a partnership first outlined in a joint development agreement signed earlier in 2026.2,3
The blocks are designed to feed the Argentina LNG project — two floating liquefaction units to be moored off the Patagonian province of Río Negro, each with a capacity of 6 million metric tons per annum and a combined target of 12 mtpa. A final investment decision is scheduled for the second half of 2026.2,3
For XRG — the international investment arm of Abu Dhabi National Oil Company — the deal advances a goal announced in June 2025 of building a top-five integrated gas and LNG business with capacity of 20 to 25 mtpa by 2035.3 South America's underdeveloped liquefaction capacity and Vaca Muerta's demonstrated shale productivity make Argentina one of the few geographies where new LNG supply at scale remains credible within this decade.
The deal ties three international partners into a shared upstream position before final investment is committed. That structure distributes risk early: if offtake terms or financing conditions shift before the H2 2026 FID, each partner carries proportional exposure, with YPF holding a slight majority at 36%.2
The Argentina LNG initiative sits inside a broader policy push by President Javier Milei, who is advancing a $30 billion energy export strategy built around Vaca Muerta aimed at generating dollar reserves for Argentina's central bank.2 The SESA consortium of energy firms deploying the floating liquefaction facilities aims to unlock roughly $2.5 billion in annual foreign exchange earnings once operational.2
Argentina's broader infrastructure pipeline is filling in quickly. Earlier this year, Citigroup, Banco Santander, and JP Morgan were among lenders working on a roughly $1 billion financing package for a gas infrastructure project by Transportadora de Gas del Sur — part of a $3 billion investment known as the NGL Project, which the company expects to generate around $1.2 billion in annual exports.1 YPF is separately pursuing financing commitments in the area of $14 billion for the LNG project itself, according to people familiar with the matter.1
Whether that financing falls into place before the FID window matters more than the upstream stakes alone. The Eni-XRG agreement gives the project credibility with lenders and potential offtakers, but it does not fund the midstream infrastructure. The two floating liquefaction vessels, port facilities, and pipeline connections from Vaca Muerta represent the bulk of the capital still uncommitted.
JKM Asian LNG prices stood at $16.05 per million British thermal units on Wednesday (2026-07-01), a level that keeps new supply projects in reasonable territory relative to long-run breakevens. The project's export orientation toward Asian buyers makes JKM the relevant benchmark for eventual offtake pricing, not NYMEX Henry Hub front-month or ICE Endex TTF front-month. At current JKM levels, a 12-mtpa export stream from Río Negro would represent a meaningful new supply vector for Asian buyers with long-dated demand obligations.2
Vaca Muerta shale oil production is already on a steep ramp, expected to rise to around 1 million barrels a day by the end of the decade from roughly 600,000 barrels currently as producers scale up under Milei's investment framework.1 Gas development has lagged the oil buildout, partly because domestic price controls historically capped returns on gas production; the LNG export route changes that calculus by anchoring returns to international prices.
The sequencing risk is real. YPF's $14 billion financing effort is still being assembled, environmental and infrastructure permitting must clear in a legal environment that has been business-friendly but volatile, and global LNG project timelines have a consistent history of slipping. The upstream stake agreements are signed; the harder commitments come in the second half of 2026.1,2
