Insights

Energy sector analyst

YPF secures long-term Vaca Muerta export volumes to Enap through 2033.

YPF and partners Vista, Shell Argentina and Equinor have signed shale oil export agreements with Chile’s Enap that run until June 2033. The contracts cover an initial combined volume of up to 70,000 barrels per day from Vaca Muerta, a key unconventional oil and gas formation. YPF’s own agreement allocates approximately 32,000 barrels per day, described as 45.45% of the total volume.

The parties state that this combined volume could generate estimated revenues of $12 billion for Argentina over the term of the contracts. The text links the deepening relationship with Enap to the rehabilitation of the Trasandino Pipeline (OTA) and the construction of the Vaca Muerta Norte Pipeline, which together facilitate exports from the Neuquén basin to Chile and potentially to Pacific markets.

The agreements illustrate sustained demand for Vaca Muerta crude and formalize export routes through existing infrastructure, including a system that currently transports 40% of exports from the Neuquén basin. Future disclosures in company filings may provide more detail on pricing formulas, cost structures and how these contracted volumes compare with YPF’s overall production and export base.
