Backers of the Vaca Muerta Sur oil pipeline approved its construction at a December 13 board meeting, advancing a project intended to carry shale crude from western Argentina to an Atlantic export outlet. The consortium put the investment at about $3 billion and was seeking entry into President Javier Milei's Large Investment Incentive Regime, or RIGI, according to the Buenos Aires Herald's account of YPF's market notice. The board's green light was a decision to proceed, not confirmation that the government had approved the project's RIGI application.
A route out of the shale basin
YPF, Argentina's state-controlled energy company, was leading the Vaca Muerta Oleoducto Sur venture alongside other oil and gas companies. The planned new stretch runs 437 kilometres from Allen in Río Negro province to Punta Colorada on the Atlantic coast, with storage and offshore loading facilities, the Herald reported. The wider route links output from Vaca Muerta in neighbouring Neuquén to the coast. Moving that crude at scale matters to an industry whose drilling capacity can outgrow existing pipes and domestic demand.
YPF told securities regulators the VMOS board had unanimously approved construction on December 13. The company expected work to begin immediately, aimed to finish in the final quarter of 2026 and targeted commercial operation for July 31, 2027, according to the Herald. Those were company targets at the time, not a guarantee of completion. Construction finance, permits, equipment and the execution of a long pipeline would determine whether the schedule held. The planned system included the export terminal and offshore loading points as well as the pipe itself.
The project's business model depends on producers committing oil volumes and capital. The Herald reported that the venture's main shareholders had committed a combined 275,000 barrels per day and assigned another 230,000 barrels per day of firm service to Chevron, Pluspetrol and Shell Argentina. These are contracted or planned transport commitments, not evidence that the pipeline was already moving that volume. YPF's role was important, but the report described it as having a minority stake in the operating venture rather than sole control over other producers' export capacity.
The investment regime's real test
The consortium submitted its RIGI proposal on November 15 and awaited an answer after a statutory review period, the Herald reported. That distinction matters amid competing claims to be the first project under the scheme. A company can decide to invest, submit an application and prepare construction without having secured the government's final approval for RIGI benefits. The regime, enacted in the June Ley Bases, offers qualifying large projects tax, customs and foreign-exchange advantages designed to compensate for Argentina's history of unstable economic rules.
Supporters argue that such long-term assurances make otherwise difficult export infrastructure bankable and help generate future foreign-currency earnings. Critics interviewed by the Herald in its earlier RIGI analysis questioned the generosity of the benefits and whether the rules sufficiently encourage domestic suppliers. The pipeline could therefore become a test both of the engineering and of the public bargain: how much additional investment incentives actually unlock, and how the returns are shared with provinces and the national economy.
A board decision was a meaningful step for an oil sector looking beyond the domestic market. But the government's investment story still needed an approved application, financing, physical construction and ships loading cargo. Until then, the promised export capacity and the RIGI benefits belonged to the project's plans rather than its completed record.
