Argentina's state-owned YPF advanced its transformation into a shale company in the fourth quarter of 2025, as it completes its divestment of conventional blocks.
"We are committed to becoming a significant shale producer," chief executive Horacio Marin said during a quarterly investor report on Friday.
Shale oil production rose by 35pc to 165,000 b/d in 2025 from a year before. Output surged in the fourth quarter, quickening to a 42pc increase to 196,000 b/d from the same period in 2024. The company forecasts shale oil output at 215,000 b/d in 2026.
Conventional production fell to 90,000 b/d in 2025, a 32pc drop from 2024. Output was down sharply in the final quarter at 68,000 b/d, a 48pc decline from the same period a year prior.
Shale gas production reached 23.3mn m³/d in 2025, up by 14pc from the previous year. It averaged 19.5mn m³/d in the fourth quarter, up from 19.3mn m³/d in the same period a year before.
The jump in shale production was offset by a decline in conventional production.
The drop in conventional production translated into a 3pc overall decline in gas production to 36.2mn m³/d in 2025 and a 14pc decline to 29.6mn m³/d in the fourth quarter.
Conventional and tight gas production was 13mn m³/d in 2025, down from 17mn m³/d a year before. The drop was more pronounced in the fourth quarter, with conventional output at 10.1mn m³/d, down from 15mn m³/d in 2024.
The pivot toward a full shale company includes the sale or transfers of all conventional assets. YPF has unloaded 45 of the 48 conventional blocks in the first phase of its divestment. It plans to get rid of the rest this year, with 13 blocks in a second phase in the transfer process.
YPF will not produce conventional oil or gas in 2027, Marin said, adding that he does not expect an overall increase in production this year. But that would change in 2027 with the completion of new midstream and downstream infrastructure.
YPF leads the Vmos consortium that is building a new 430km (260-mile) oil pipeline from the Vaca Muerta unconventional formation to the southern coast. It will start moving 180,000 b/d in the final quarter of 2026, increasing to 555,000 b/d next year and, potentially, 700,000 b/d by 2030.
Meanwhile, the Southern Energy consortium is working on a 6mn metric tonne (t)/yr LNG export project that will use two floating LNG vessels. Operated by Argentina's Pan American Energy and Norway's Golar LNG, it will start commercial operation in 2027.
YPF and two partners, Italy's Eni and XRG — the investment arm of Abu Dhabi's National Oil Company — are working on a 12mn metric tonne/yr LNG project that will start exports in 2030-2031.
