Which three companies are developing the Vaca Muerta Basin oil and gas blocks, and what are their respective equity shares?

XRG Group, Eni Group, and Argentina's national oil company YPF are jointly developing three onshore oil and gas blocks in the Vaca Muerta Basin. According to the agreement, XRG and Eni each hold a 32% equity stake, while YPF retains a 36% stake.

What is the strategic significance of these blocks for XRG’s global energy ambitions?

The blocks serve as the core gas supply base for Argentina’s planned annual 12-million-ton liquefied natural gas (LNG) integrated project, aligning closely with XRG’s global natural gas strategy. Securing upstream rights in the resource-rich Vaca Muerta Basin provides XRG with long-term, stable gas reserves and enables access to global markets via Argentina’s LNG export initiative, thereby strengthening its global energy portfolio’s resilience. Additionally, through this partnership—where YPF operates the blocks and supplies gas to two planned floating LNG units while commercializing associated condensate—XRG establishes a deep strategic tie with YPF and advances toward becoming a global integrated energy platform spanning natural gas, LNG, and petrochemicals.
