The Vaca Muerta shale play in Argentina's Neuquen basin is a globally significant unconventional resource, transforming the country's oil and gas industry. Since its major discovery in 2010 and the commencement of commercial-scale production in 2013, output has grown steadily. Current production is approximately 550,000 barrels per day of shale oil and 100 million cubic metres per day of shale gas.

Robust Growth Projections

Analysts are highly optimistic about Vaca Muerta's future. Forecasts indicate an annual oil production growth rate of about 20% through the end of the decade, potentially reaching over 1 million barrels per day. By 2030-2032, oil output is projected to be between 1 million and 1.2 million bpd, with an upside to 1.4-1.5 million bpd. This growth is expected to offset declines in Argentina's conventional production, driven by increased drilling and improved operational execution by companies.

The Paradox of Major Company Exits

Despite these strong prospects, several international supermajors, including ExxonMobil, Petronas, and Equinor, have sold their Vaca Muerta assets, with speculation about others like Shell and TotalEnergies potentially following. This exodus is considered counterintuitive given the global industry's need to replenish undeveloped project inventories.

Reasons Behind the Divestments

Analysts cite multiple factors for the departures. A primary concern is "above the ground risk," referring to political and regulatory instability in Latin America, where frameworks can shift with changes in government, creating an unfavorable environment for international companies that prioritize stability. The current Argentine administration is viewed as more industry-friendly, which has increased asset valuations, making it an opportune time for some companies to sell. Furthermore, exiting companies often lacked the scale in Vaca Muerta to justify the large, long-term capital investments required for infrastructure and pipelines needed to be efficient and profitable. Instead, they chose to crystallize value and reallocate capital to other assets or regions, such as offshore projects, that better align with their core strategies and portfolio management goals.

Continued Investment and Future Outlook

The departure of some majors does not indicate a lack of interest in Vaca Muerta. Domestic companies like YPF, Vista Energy, and Tecpetrol, which are committed to making the necessary large-scale investments, are actively expanding. Overall investment in Argentina's shale sector is projected to rise significantly, with estimates showing a 17% increase from $9.4 billion in 2025 to nearly $11 billion in the current year. The play remains a focal point for growth, with its development trajectory now increasingly driven by focused, scaled operators.
