A consortium led by the U.S.-based construction firm MasTec, founded by Jorge Mas, has secured a significant contract to develop infrastructure for the transport of natural gas from the Vaca Muerta shale formation in Argentina. The project, which involves the construction of gas pipelines to the coastal region of Sierra Grande, marks a strategic expansion for Mas—who is also the co-owner of Inter Miami CF—into the South American energy sector.
The selection of the MasTec-led group represents a shift in the landscape of major energy infrastructure projects in Argentina, which have historically been dominated by local conglomerates such as Techint. The project is linked to the broader push for the “Argentina LNG” initiative, aimed at scaling up the country’s capacity to process and export the vast gas reserves found in the Neuquén Basin.
Infrastructure Expansion in Vaca Muerta
As state-controlled energy company YPF continues to tender key projects, the focus has moved toward creating robust evacuation capacity. The pipeline project awarded to the consortium, which includes the Italian firm Bonatti alongside MasTec, is designed to serve the industrial requirements of the energy sector’s export ambitions.

For Jorge Mas, this venture into Vaca Muerta is a high-profile diversification of his business portfolio.
Competitive Dynamics and Industry Shifts
The energy infrastructure sector in Argentina has long been characterized by the presence of large, established domestic players. The entry of MasTec into the Vaca Muerta pipeline construction phase has highlighted the competitive nature of YPF’s recent tenders.
Strategic Importance of the Sierra Grande Pipeline
The pipeline connecting the Neuquén Basin to Sierra Grande is a critical component of the national strategy to enable large-scale LNG exports.
