Vaca Muerta's Pacific Play: A Second Export Door Through Chile

The president of Neuquén's chamber of chemical, petrochemical and related industries, Yamil Quispe, says Vaca Muerta has moved beyond the promise stage and now anchors Argentina's pipeline of large-scale investment projects. According to the chamber, the shale formation concentrates 70% of the funds currently being evaluated under Argentina's Large Investment Incentive Regime (RIGI): of US$7.82 billion under review, US$5.4 billion is tied to shale gas extracted through fracking.

Quispe argues the field should not rely on a single export route. He proposes a dual strategy: keep the Atlantic corridor through Bahía Blanca and Río Negro for Europe and the South Atlantic, while developing a corridor across Chile to send liquefied natural gas (LNG) to Asia-Pacific buyers. To make that work, he wants to reactivate existing infrastructure — the Trans-Andean Oil Pipeline (OTASA), GasAndes and the Gasoducto del Pacífico — and, as the decisive step, build a liquefaction plant in Chile's Biobío region. Without such a plant, gas currently reaching Chile by pipeline cannot be loaded onto ships as LNG, which is the product that opens access to Asian markets.

Quispe said the Pacific route would cut roughly nine to ten days of sailing time to Japan, South Korea, China or India compared with going around the Atlantic, and that in a commodity market the freight saving is a direct competitive margin. He also noted Asia-Pacific accounts for around 70% of global LNG demand and that large importers are seeking to diversify suppliers to secure their energy transitions. On the Chilean side, he pointed to the chamber's position as the 'third ring' of Vaca Muerta suppliers and said the goal is to bring Chilean suppliers — and Chile's mining experience — into Argentina's gas sector.

What a Biobío LNG Plant Would Mean for Argentine Gas Export Math

The RIGI Numbers Remain a Proposal, Not a Final Tally

The 70% figure is the chamber's own reading of project flow under RIGI, the incentive regime designed to attract large capital with tax, customs and exchange-rate benefits. If accurate, it shows shale gas dominates the current queue of investment proposals and strengthens the argument that Vaca Muerta is the backbone of Argentina's export ambitions. But RIGI evaluation is not the same as approval: the final commitment of capital depends on official sign-offs, project financing and market prices, none of which is detailed in the chamber's statement.

Freight Is the Real Logic Behind the Pacific Corridor

The commercial case rests on shipping distance. A saving of nine to ten days on voyages to Japan, South Korea, China and India is meaningful because freight is a significant share of delivered LNG cost, and Asia-Pacific buyers hold most of the world's demand. However, the route only works if enough gas actually reaches Chile and if liquefaction capacity exists at the port. OTASA, GasAndes and Gasoducto del Pacífico are existing assets, but their current capacity, condition and commercial terms are not addressed here. The Biobío plant proposal, first raised by the chamber in 2020, remains a project concept rather than a financed development.

What Chile Gains — and Would Need to Deliver

For Chilean firms, the proposal frames Biobío and the wider Pacific coast as a potential exit point for Argentine gas, creating demand for engineering, construction and port services. The chamber explicitly wants to transfer lessons from Chile's mining supply chain to gas development in Argentina, which could open a new export-services market for Chilean contractors. The counterweight is that an LNG plant requires large capital commitments, environmental permitting and long-term gas supply agreements — none of which has been confirmed by any company or government authority.

Watching the Vaca Muerta–Chile Corridor: Signals for Investors and Suppliers

For companies, investors and suppliers watching the Argentina–Chile gas corridor, the relevant next steps follow from the specifics in the chamber's statement.

  • Treat the US$7.82 billion RIGI evaluation figure and the US$5.4 billion shale-gas share as the chamber's estimate; track official RIGI approval decisions to verify committed capital.
  • For midstream and infrastructure investors, assess the current operating status and capacity of OTASA, GasAndes and Gasoducto del Pacífico; the reactivation call implies these assets may need investment before they can serve an LNG export chain.
  • Chilean engineering, construction and mining-services firms should watch for formal Biobío LNG project announcements; the chamber identified Chilean suppliers and mining know-how as a channel into Vaca Muerta's 'third ring'.
  • Asian LNG importers evaluating Argentine supply should weigh the nine-to-ten-day freight advantage of a Pacific route against the absence of a committed liquefaction plant and supply agreements.
  • Policymakers in Biobío and Neuquén should expect permitting and cross-border energy decisions to determine whether the corridor moves from advocacy to construction.

Risk & Opportunity Assessment

Commercial RiskMediumThe corridor's economics rest on a US$5.4 billion shale-gas project pipeline still under RIGI evaluation and on a Biobío liquefaction plant that remains a proposal; neither financing nor supply agreements are confirmed.
Competitive RiskMediumAsia-Pacific LNG buyers already have established suppliers in the United States, Qatar and Australia; a nine-to-ten-day freight saving helps Argentina compete only if liquefaction capacity actually exists.
Regulatory RiskMediumRIGI review, cross-border pipeline use and Chilean permitting for a Biobío LNG plant all sit between the chamber's proposal and an operating export route.
Reputation RiskLowThe claims are advocacy from an industry chamber; if the Pacific export route stalls, the risk is overstated expectations rather than direct financial loss.
Technology DisruptionLowNo new technology is required; the proposal relies on proven fracking, pipeline and LNG liquefaction systems already in commercial use.
Commercial OpportunityHighAsia-Pacific accounts for roughly 70% of global LNG demand and the Pacific route cuts nine to ten days of freight time, while Chile's mining supply chain offers a ready pool of contractors.
