Vaca Muerta’s Pacific Question: Can Chile Become Argentina’s Oil Exit to Asia?
Chile is offering Argentina a Pacific route for Vaca Muerta energy exports. The hard infrastructure story is more precise: the Pacific route is already becoming real for crude oil, while Argentina’s LNG export future still points mainly toward Río Negro and the Atlantic.
Chile can become a real Pacific exit for Vaca Muerta crude oil. Argentina’s LNG strategy is taking a different route.
The Trans-Andean oil route is operating again, and ENAP has signed long-term contracts with YPF, Vista Energy, Shell Argentina and Equinor to receive crude oil from Vaca Muerta until June 2033. That gives Neuquén a concrete corridor toward Chile’s Biobío region and the Pacific.
Argentina’s larger LNG export strategy is being built around Río Negro and Atlantic-facing infrastructure. Chile’s Pacific pitch is therefore strongest as an oil corridor and as a second coast for Vaca Muerta, with LNG still at the level of a longer-term feasibility discussion.
Core market reading:
Vaca Muerta is becoming an export geography story. The strategic question is whether Argentina remains mainly an Atlantic exporter, or whether Chile turns part of Vaca Muerta into a Pacific-facing oil platform.
Why this is an oil question first
Chile’s offer to connect Vaca Muerta with Pacific markets sounds like a broad energy-integration story. In political language, it includes ports, logistics, LNG terminals, regulation, energy security and future routes to Asia.
For market analysis, the story needs a sharper distinction. The Pacific corridor is concrete today mainly for crude oil. Oil can move through existing pipeline infrastructure from Neuquén into Chile. It can supply ENAP’s refineries and, under the right conditions, use Chilean port infrastructure for Pacific shipments.
Natural gas follows a more complex industrial path. Gas can move across borders through pipelines, and Chile has LNG infrastructure. A large-scale export platform for Argentine LNG requires liquefaction capacity, dedicated upstream supply, pipeline capacity, financing, long-term offtake and regulatory certainty. Argentina’s most advanced LNG export path currently points to Río Negro.
This distinction gives the article its analytical edge: Vaca Muerta’s Pacific question is concrete for oil and still exploratory for LNG.
"The Pacific route becomes strongest when it is read as an oil corridor with strategic upside."
The oil route to Chile is already operating
The hard starting point is the ENAP agreement. In December 2025, Chile’s state oil company announced long-term contracts with YPF, Vista Energy, Shell Argentina and Equinor for the supply of crude oil from Vaca Muerta. The contracts run until June 2033 and have a projected value close to US$12 billion.
The crude moves through the Oleoducto Trasandino, a pipeline of more than 400 kilometers built in the 1990s. It connects Puesto Hernández in Neuquén with ENAP’s facilities in Hualpén, in Chile’s Biobío region.
After 17 years of inactivity, the pipeline restarted oil shipments in 2023 following rehabilitation work. Since then, shipments have averaged around 40,000 barrels per day. With the new contracts, throughput is expected to reach the pipeline’s full capacity of 110,000 barrels per day.
Buenos Aires Times reported that the initial combined volume under the deal is up to 70,000 barrels per day. ENAP stated that the supply would cover around 35 percent of its annual crude oil demand. For Chile, the deal strengthens supply security. For Argentina, it creates export revenue and opens a route across the Andes.
Talcahuano is the Pacific detail that makes the story strategic
The strongest Pacific point is the role of ENAP’s logistics system. The corridor supplies Chilean refining demand and can also support export flows through the Pacific.
ENAP stated that the agreement reinforces its logistics business because it enables the export of Vaca Muerta crude through the Terminal Marítimo San Vicente in Talcahuano. That point turns Talcahuano into more than a destination for Argentine crude. It gives the corridor a Pacific-facing hub.
This is where the Asia angle becomes plausible. Chile’s ports face the Pacific. Argentina’s main hydrocarbon basin sits on the other side of the Andes. If crude can cross the mountains reliably, Chile gives Vaca Muerta a route toward Pacific markets without sending every barrel toward the Atlantic.
The limitation is capacity. The Pacific oil route is useful and commercially real, with a smaller scale than the major Atlantic export system. It gives Argentina optionality, Chile supply security and Biobío/Talcahuano a stronger role in the Southern Cone’s energy map.
Chile’s opportunity is focused and credible.
It can become the Pacific outlet for a defined share of Vaca Muerta crude oil, alongside the larger oil and LNG infrastructure that Argentina is building on the Atlantic side.
The Atlantic route is the larger counterweight
The reason the Pacific story needs scale discipline is Vaca Muerta Oil Sur. VMOS is the larger oil export corridor. It links the Neuquén basin with the Atlantic coast in Río Negro and the planned export terminal at Punta Colorada.
Global Energy Monitor lists Phase 2 of the Vaca Muerta Sur Oil Pipeline, from Allen to Punta Colorada, with a capacity of 550,000 barrels per day, expandable to 700,000 barrels per day. GEM also lists the phase at 437 kilometers and US$3 billion in cost.
The timeline gives the Atlantic route a concrete watch point. GEM records plans for full commercial operation in July 2027, with commercial operations reported as on track to begin as early as December 2026. As of January 2026, the project was reported to be 51 percent complete.
This changes the scale comparison. A 70,000-barrel-per-day initial oil corridor to Chile is strategically meaningful. A 550,000-barrel-per-day Atlantic route is structurally larger. If fully developed, VMOS becomes the main oil-export backbone for Argentina’s shale boom.
The Chile route remains important as a second route, a diversification option and a regional integration case. For exporters, optionality has value. For Chile, the route has supply and logistics value. For Argentina, it reduces dependence on one coast, one terminal system and one export geography.
"The Pacific route is a corridor of optionality. The Atlantic route is the scale project."
Why LNG is different
The LNG question is the weak point in a broad claim that Chile can become Argentina’s energy exit to Asia. The main Argentina LNG projects are being structured around Río Negro and Atlantic-facing export infrastructure.
Reuters reported that YPF and Eni reached an agreement with XRG, the investment arm of ADNOC, to join an LNG project linked to Vaca Muerta. The project involves floating liquefaction units at a port in Río Negro, with gas arriving from Neuquén through pipeline infrastructure. Reuters also reported that LNG exports are expected to start by 2030 if the project advances.
Eni describes Argentina LNG as a project expected to deliver 12 million tonnes per year of LNG capacity through two floating LNG facilities of 6 million tonnes per year each. The project includes production, processing, transportation and LNG export infrastructure.
A Chilean LNG role remains possible over a longer horizon. Chile has LNG terminals, Pacific ports and energy-integration experience. The concrete industrial path for Argentine LNG is currently Atlantic-oriented. For now, Chile’s strongest claim is oil logistics and Pacific port optionality.
Key distinction:
Oil can use the revived Trans-Andean route. LNG needs a much larger liquefaction and export system, and Argentina is currently developing that system toward Río Negro.
The old gas crisis still shapes the trust question
Energy corridors are built with steel, contracts and money. They also depend on trust. Argentina and Chile learned this in 2004.
In April 2004, Argentina began cutting natural gas exports to Chile. Inter Press Service described the episode as a major Chilean energy crisis. Chile had built its gas strategy around Argentine supply, and the cuts exposed the fragility of cross-border dependence when domestic politics and supply constraints intervene.
This history does not block new integration. It explains why the new integration needs stronger commercial discipline. Chile knows that energy dependence on Argentina can become politically painful. Argentina knows that export credibility matters if it wants to become a stable supplier of oil, gas and LNG.
The roles have changed. In 2004, Argentina protected its domestic market by cutting exports. In the Vaca Muerta phase, Argentina wants export revenue, foreign currency and market access. This time, Argentina has something to lose if reliability fails.
The infrastructure question is also a credibility question.
Chile can offer ports and logistics. Argentina can offer Vaca Muerta supply. A durable energy corridor needs stable rules, predictable flows and contracts that survive pressure in winter, elections and price shocks.
What the corridor means for market observers
For market observers, the Chile route should be read as a focused opportunity. It works as an oil corridor with strategic upside, alongside Argentina’s larger Atlantic strategy.
The corridor strengthens three things at once. First, it gives Chile more supply security and reduces dependence on distant maritime imports. Second, it gives Argentina a Pacific-facing route for crude oil. Third, it turns Biobío and Talcahuano into more relevant nodes in the Southern Cone’s energy geography.
The larger question is whether the corridor remains a supply arrangement for ENAP or becomes a broader export platform. That depends on volumes, spare capacity, terminal performance, commercial agreements, price differentials and regulatory reliability.
For companies, the opportunity extends beyond production. It can emerge in pipeline operation, port services, storage, measurement, maintenance, engineering, environmental compliance, maritime logistics, customs systems, insurance, data services and cross-border project management.
Econosur’s European Suppliers in Vaca Muerta report examines how industrial suppliers reach this demand through operators, project companies, EPC and engineering structures, integrators, distributors and local service platforms rather than through one single Vaca Muerta market.
- Oil logistics: pipeline capacity, terminal operations, storage, maritime services and port handling.
- Cross-border infrastructure: maintenance, monitoring, metering, safety systems and regulatory coordination.
- Energy trading: crude supply contracts, Pacific market access, pricing and offtake structures.
- LNG development: liquefaction, upstream gas supply, pipeline links and Atlantic export infrastructure.
- Risk management: winter supply pressure, political reliability, environmental permitting and contract enforcement.
- Regional integration: Neuquén, Biobío, Talcahuano and Río Negro as nodes in a larger energy map.
What to watch next
The first point to watch is the actual flow through the Oleoducto Trasandino. The route is now backed by long-term contracts, with commercial importance depending on stable volumes and operational reliability.
The second point is Talcahuano. If the Terminal Marítimo San Vicente handles more Vaca Muerta crude for third markets, the Pacific route becomes more than a bilateral supply story.
The third point is VMOS. The key time window is December 2026 to July 2027: early commercial operation has been described as possible from December 2026, while full commercial operation is listed for July 2027. If the Atlantic pipeline advances toward full operation and later expansion, it will dominate Argentina’s oil-export scale.
The fourth point is Argentina LNG. If YPF, Eni and XRG move from development agreements into final investment decisions, LNG will strengthen the Atlantic side of the export map.
The fifth point is political reliability. Argentina and Chile can build a practical energy corridor, but the old gas crisis shows that integration works best when infrastructure is matched by trust and predictable rules.
Vaca Muerta’s larger export question
Vaca Muerta is becoming an export project with two different geographies.
Oil already has a working Pacific option through Chile. The ENAP contracts, the revived Trans-Andean pipeline and the Talcahuano terminal give the corridor commercial substance. This route matters because it connects Neuquén with the Pacific and gives Argentina an additional export direction.
LNG is moving differently. The larger LNG export strategy is being developed through Río Negro and the Atlantic. That path requires greater scale, more capital, more infrastructure and longer timelines.
The strongest conclusion is focused: Chile can become Vaca Muerta’s Pacific oil exit, while Argentina’s LNG future stays Atlantic-facing.
That distinction gives the story its strategic value. Vaca Muerta may become a two-ocean platform: Atlantic at scale, Pacific with optionality.

Commercial & Infrastructure Questions
The Pacific route is already more than a political concept, but its commercial significance depends on scale, infrastructure use and the procurement structures around the corridor. Three questions matter most for suppliers, investors and market-entry teams.
How much Vaca Muerta crude can realistically reach Pacific markets through Chile?
The route is commercially real, but it is capacity-constrained. The article records long-term ENAP supply contracts, initial combined volumes of up to 70,000 barrels per day and roughly 110,000 barrels per day of capacity on the Trans-Andean oil pipeline. That makes Chile a functioning export direction, but not an unlimited alternative to Argentina’s Atlantic system.
How much crude can move onward to third-country Pacific markets depends on more than nominal pipeline capacity. Stable upstream flows, spare transport capacity, terminal performance at San Vicente/Talcahuano, commercial agreements and the balance between ENAP supply needs and export use all affect the corridor’s realistic scale.
How does the Vaca Muerta–Chile Pacific route compare with the VMOS Atlantic export corridor?
The two routes serve different strategic functions. Chile provides an operating Pacific option, diversification and access to a second coast. VMOS is the scale project: the article cites Phase 2 at 550,000 barrels per day, expandable to 700,000 barrels per day, far above the present Trans-Andean system.
For investors and exporters, the useful distinction is therefore not which route “wins.” The Pacific corridor provides optionality and regional integration; VMOS is designed to become the larger oil-export backbone. The commercial value of Chile rises if Talcahuano develops beyond an ENAP supply point into a repeatable platform for Pacific third-market shipments.
Which infrastructure and supplier opportunities are emerging along the Vaca Muerta–Chile oil corridor?
Relevant demand areas extend beyond crude production. The corridor can create requirements in pipeline operation, maintenance, metering, storage, port services, engineering, environmental compliance, maritime logistics, customs systems, data services and cross-border project management.
These categories should not be read as automatically open procurement opportunities. Commercial accessibility depends on the asset owner, project stage, incumbent suppliers, qualification procedures, local service expectations and whether procurement sits with an operator, engineering contractor, terminal, logistics provider or specialist partner.
Public sources can establish pipeline capacity, contract announcements, project design, named operators and official export ambitions. They do not reliably show current spare capacity, active procurement packages, incumbent supplier positions, qualification windows, buyer-level technical requirements or which market-entry route remains realistically open for a specific supplier.
That gap is where project verification and primary market research become commercially useful.

Discuss a Research QuestionFAQ
Can Chile become Argentina’s energy exit to Asia?
Chile can become a real Pacific exit for part of Vaca Muerta’s crude oil exports. The existing Trans-Andean oil route and ENAP’s long-term contracts make the oil corridor concrete. Argentina’s LNG projects are being structured mainly around Río Negro and the Atlantic.
Is the Pacific route mainly about oil or gas?
Today it is mainly an oil question. Crude oil can move through the Oleoducto Trasandino toward ENAP’s facilities in Biobío and the San Vicente terminal in Talcahuano. LNG exports are being developed mainly through Argentina LNG and Atlantic-facing infrastructure in Río Negro.
What is the Oleoducto Trasandino?
The Oleoducto Trasandino is a pipeline of more than 400 kilometers that connects Puesto Hernández in Neuquén with ENAP’s facilities in Hualpén, Chile. It was inactive for 17 years and restarted shipments in 2023.
Why does VMOS matter?
Vaca Muerta Oil Sur is the larger Atlantic-facing oil export project. Phase 2 is listed by Global Energy Monitor at 550,000 barrels per day, expandable to 700,000 barrels per day, with a 437-kilometer route from Allen to Punta Colorada.
Why does the 2004 gas crisis still matter?
In 2004, Argentina began cutting natural gas exports to Chile, triggering a major energy crisis. That history still matters because cross-border energy corridors depend on infrastructure, trust, contracts and political reliability.
What is the main strategic question?
The main question is whether Vaca Muerta becomes a one-coast export project through the Atlantic, or a two-ocean platform where part of its crude oil reaches Pacific markets through Chile.
How much Vaca Muerta crude can realistically reach Pacific markets through Chile?
The route is commercially real but capacity-constrained. The article records long-term ENAP supply contracts, initial combined volumes of up to 70,000 barrels per day and approximately 110,000 barrels per day of Trans-Andean pipeline capacity. Third-country Pacific exports also depend on stable flows, spare capacity, terminal performance and commercial arrangements at Talcahuano.
How does the Vaca Muerta–Chile Pacific route compare with the VMOS Atlantic export corridor?
The Chile route provides an operating Pacific option and diversification value, while VMOS is the larger-scale Atlantic export project. The strategic distinction is Pacific optionality versus Atlantic scale.
Which infrastructure and supplier opportunities are emerging along the Vaca Muerta–Chile oil corridor?
Relevant demand areas include pipeline operation, port services, storage, metering, maintenance, engineering, environmental compliance, maritime logistics, customs systems and cross-border project management. Actual procurement access must be verified by asset owner, project stage and qualification route.
