Through the reassignment of capacity it also reaches distributors, the Vaca Muerta producers that need to evacuate gas, large users and generators, and indirectly the ecosystem of transport and infrastructure services thesis. verif Mar 13, 2026 ↗

Our reading
The State unwinds the legacy contracts and frees up firm capacity so that whoever uses it contracts it: less of a bottleneck to evacuate Vaca Muerta, open access and enforceable contracts with a firm horizon to 2028. Market rules on the critical path of Argentine gas (R2/R3). thesis
Analyze this rule for my company
Where it lands, province by province2
Neuquén This is THE evacuation rule for Neuquén's gas: the reassignment of Perito Moreno pipeline capacity and the open tenders define how much additional Vaca Muerta gas reaches demand — an enabling condition for the entire incremental production plan of the basin's operators. favorable stability → long-term investment thesis
Río Negro The GPM and the Neuba system loops cross Río Negro: more firm-transported gas = more compression, work camps and pipeline maintenance on Río Negro territory, and it strengthens the case for the Golfo San Matías LNG/petrochemical corridor, which depends on guaranteed evacuation. favorable stability → long-term investment thesis
