Vista Energy Adds 66.8M Barrels in Vaca Muerta

Vista Energy reported on September 8, 2026, an estimated 66.8 million barrels of oil equivalent of proved reserves from its working interests in the Bandurria Sur and Bajo del Toro blocks. The company acquired these assets on May 7, 2026. The estimate reflects data as of December 31, 2025, and includes both developed and undeveloped volumes of crude oil, condensate, natural gas liquids, and natural gas.

The addition brings Vista Energy's pro forma total net proved reserves to 654.9 million barrels of oil equivalent as of December 31, 2025. In Bandurria Sur, where the company holds a 25.1% interest, there were 56 wells onstream and 99 remaining locations as of June 30, 2026. In Bajo del Toro, where Vista holds a 35.0% interest, there were 8 producing wells and 138 locations.

The May 7 transaction closed through deals with Equinor entities and YPF. Vista initially acquired 100% of Bandurria Sur Participaciones and a 50% stake in Bajo del Toro before partial assignments to YPF established Vista's final non-operating interests. The concessions extend into 2050 and 2055, backed by midstream agreements to transport new volumes.
