Transportadora de Gas del Sur (TGS) has taken a major step forward in Argentina’s midstream sector, confirming a final investment decision (FID) for its US$3 billion Natural Gas Liquids (NGLs) project in Vaca Muerta — now positioned as the largest liquids processing investment in the country’s history.
The company’s board has approved key commercial agreements with YPF, Pluspetrol, and Chevron, securing commitments covering more than 80% of the project’s capacity. TGS reports advanced negotiations with additional producers to fully subscribe remaining volumes.
“This is a strategic investment of great significance for Argentina’s energy development,” said Oscar Sardi, chief executive officer of TGS. “With an investment of US$3 billion, the project will enable exports of approximately US$1.2 billion per year, reaffirming our commitment to strengthening the country’s productive infrastructure.”
The development is designed to alleviate one of the critical bottlenecks facing Vaca Muerta: the handling and monetization of associated gas and its liquid components. By enabling the recovery and processing of NGLs, the project supports both increased crude oil production and improved gas transportation through existing trunk and export pipelines.
Industry stakeholders have long identified insufficient liquids processing infrastructure as a limiting factor for full-scale unconventional development in the basin. TGS’s investment aims to unlock additional production capacity while strengthening Argentina’s export position.
The NGLs project includes new infrastructure across the gas value chain:
- Expanded gas processing facilities at the Tratayén plant
- A multi-product pipeline linking Tratayén to Bahía Blanca
- A fractionation facility and storage plant in Bahía Blanca
- Upgrades to the port terminal to support exports
- A 62-mile (100-km) gas-stream segregation pipeline
Once operational, the system will industrialize liquids extracted from produced gas, creating a fully integrated processing and export chain.
TGS has described the project as the largest of its kind not only in Argentina but in the broader region, marking the first major liquids processing development in the country in over 25 years. Backers of the project have emphasized its role in supporting long-term energy growth and improving Argentina’s trade balance through increased export capacity.
