History of the transport system

Without pipelines, oil and gas go nowhere. The story of how the network was built: the major Gas del Estado pipelines, YPF's oil pipelines to Bahía Blanca, the interconnections with Bolivia, Chile, Brazil and Uruguay, and the projects to take Vaca Muerta production out.

What it means for a supplier

  • Every new pipeline is a project of hundreds of kilometers: pipe, coating, welding, non-destructive testing, earthworks, special crossings, pumping or compression stations, SCADA.
  • Operating and maintaining the network (inspection with smart pigs, cathodic protection, repairs) are long-term contracts.
  • Details on each pipeline that exists today are in Oil and gas pipelines.
