Argentina’s oil and natural gas industry is being reorganized around Vaca Muerta, the large shale formation beneath Neuquén and neighboring provinces. Conventional fields remain active in several basins, but unconventional production now provides the main source of national growth. This expansion has helped Argentina move away from recurring energy shortages and toward a future in which hydrocarbons could become one of its largest export industries.
The shift is especially important because Argentina has substantial domestic energy demand, an established refining system, and a history of importing gas during periods of peak consumption. Rising shale production therefore has two effects. It improves domestic supply while also creating more crude oil and natural gas that can be sold abroad.
Oil output has continued rising as companies drill longer horizontal wells, improve completion methods, and concentrate investment in the most productive parts of Vaca Muerta. Argentina produced about 865,000 barrels of oil per day in February 2026, according to industry data, while Neuquén Province alone supplied more than 600,000 barrels per day. The province’s output was around 30% higher than a year earlier.
Vaca Muerta’s importance extends beyond a single production record. The formation accounted for an estimated 62% of Argentine oil output during the first ten months of 2025, and the US Energy Information Administration expected national production to average about 810,000 barrels per day in 2026.
This gives Argentina a different position from many mature South American producers. Its most important oil region is still expanding, while older conventional fields are generally declining. The question is no longer whether Vaca Muerta can produce at commercial scale. The central issue is whether pipelines, storage facilities, export terminals, drilling services, and investment can expand quickly enough to support the next stage of development.
Oil Exports Depend on New Transport Capacity
Vaca Muerta produces a light, relatively low-sulfur crude commonly marketed as Medanito. This quality is attractive to refineries, but production growth has repeatedly approached the limits of Argentina’s existing pipeline system.
Several projects have therefore focused on moving more crude from Neuquén toward domestic refineries and export points. The Vaca Muerta Norte pipeline, completed in 2023, connected producing areas around La Amarga Chica with YPF’s wider transport network. It was part of a broader effort to remove logistical restrictions that had limited production growth.
Additional capacity is being developed toward the Atlantic coast. The Vaca Muerta Sur project is intended to connect Neuquén with a new export system in Río Negro Province, allowing larger volumes to reach international markets without relying entirely on older routes through central Argentina.
This infrastructure is essential because exports are rising alongside production. Argentina exported an average of approximately 180,000 barrels per day during the first half of 2025, compared with 154,000 barrels per day in 2024. Most of that volume was Medanito crude from Vaca Muerta and other Neuquén Basin fields.
YPF is also planning a much larger expansion of its upstream operations. In May 2026, the state-controlled company submitted a proposed US$25 billion development known as LLL under Argentina’s incentive regime for large investments. The project is designed to produce 240,000 barrels per day by 2032 through more than 1,100 wells, with the resulting crude intended for export.
Projects of this size could make oil a more reliable source of foreign currency for Argentina. That matters in an economy that has frequently faced pressure on its international reserves. However, reaching the projected volumes will require sustained drilling, competitive production costs, stable regulations, and access to international finance.
Natural Gas Growth Changes the Domestic Market
Natural gas has long played a major role in Argentina’s electricity generation, industrial activity, household heating, and transport sector. Domestic demand rises sharply during the Southern Hemisphere winter, when pipeline imports and LNG cargoes have often been needed to supplement local production.
Vaca Muerta has changed that balance. Argentina produced an average of around 5 billion cubic feet of natural gas per day during the first nine months of 2024, while August production reached its highest monthly level in 21 years. By September 2024, Vaca Muerta supplied approximately 74% of national gas output.
The Néstor Kirchner Gas Pipeline, later renamed the Perito Francisco Pascasio Moreno Gas Pipeline, became one of the most important parts of this transition. Its first stage increased the amount of gas that could move from Neuquén toward the main population and industrial centers around Buenos Aires. Further expansion and associated pipeline work could reduce the need for imported LNG and Bolivian pipeline gas.
Argentina has also begun reversing parts of its regional gas network. Pipelines originally constructed to bring Bolivian gas south can increasingly move Argentine gas north toward provinces that previously depended on imports. Additional connections may support exports to Chile, Brazil, Uruguay, and other regional markets.
Seasonality remains important. Argentina may produce enough gas for much of the year while still facing tighter conditions during cold winter periods. Storage capacity, pipeline compression, and flexible supply contracts will therefore remain necessary even as annual production rises.
LNG Could Take Argentine Gas Beyond South America
Regional pipeline exports alone cannot absorb the full scale of Vaca Muerta’s potential production. Argentina is therefore pursuing liquefied natural gas projects that would allow gas to reach markets in Europe and Asia.
The Argentina LNG initiative led by YPF has evolved toward floating liquefaction rather than a single large land-based plant. YPF, Italy’s Eni, and Abu Dhabi-based XRG signed a joint development agreement in February 2026 for a project expected to provide 12 million tonnes of annual LNG capacity through two floating facilities. The plan would integrate gas production, processing, pipeline transportation, and export infrastructure.
Floating LNG units could reduce the time required to begin exports and limit some of the construction risks associated with a large coastal plant. They still require major supporting investment, including dedicated gas production, pipelines across Patagonia, port facilities, and long-term sales agreements.
A separate Southern Energy project involving YPF and private partners is also designed around floating liquefaction vessels. These projects could create a new export market for gas that is currently restricted by domestic demand and regional pipeline capacity.
The scale of investment remains the main test. LNG developments require billions of dollars before exports begin, and buyers generally expect long-term commercial and regulatory stability. Argentina must therefore demonstrate that export rules, currency arrangements, taxation, and domestic supply obligations will remain predictable across political cycles.
YPF Remains Central, but Private Producers Drive Competition
YPF occupies a unique position in Argentina’s hydrocarbons industry. It is the largest domestic producer, an important refiner and fuel retailer, and the main sponsor of several strategic pipeline and LNG projects. Its decisions strongly influence the pace of development across Vaca Muerta.
The wider industry is more diverse. Major operators include Pan American Energy, Vista Energy, Tecpetrol, Pampa Energía, Pluspetrol, Shell, Chevron, TotalEnergies, and several local or international partners. Some concentrate on shale oil, while others have larger positions in natural gas or conventional production.
Competition among these companies has helped improve drilling productivity. Operators have reduced the time required to complete wells, expanded the use of local sand and services, and developed larger connected production areas. Vaca Muerta increasingly operates as an industrial system rather than a collection of isolated wells.
Even so, the sector remains sensitive to national economic policy. Capital controls, regulated domestic prices, import restrictions, inflation, and uncertainty over access to export revenue have all affected investment decisions in the past.
The Incentive Regime for Large Investments, known as RIGI, is intended to address some of these concerns by offering fiscal and regulatory protections to qualifying projects. Its effectiveness will depend on whether investors believe those protections will remain durable.
Argentina Moves From Energy Deficit Toward Export Expansion
Argentina’s oil and gas sector is now entering a different phase. The first stage of Vaca Muerta development proved that the formation could support large-scale commercial production. The next stage is focused on converting that production into reliable export income.
Oil is moving fastest because crude can be exported once sufficient pipeline and terminal capacity is available. Natural gas requires a more complex combination of domestic pipelines, regional connections, liquefaction facilities, and long-term contracts.
The opportunity is substantial. Higher production can reduce import costs, strengthen energy security, support industrial development, and generate foreign currency. It can also expose Argentina more directly to international oil and gas prices.
The sector’s future will be determined less by the availability of resources than by execution. Pipeline construction, LNG financing, regulatory consistency, operating efficiency, and access to capital will decide whether Argentina becomes a major long-term exporter or remains a producer whose growth repeatedly encounters infrastructure and economic limits.
