GeoPark strengthens its presence in Latin America after completing the purchase of assets in Vaca Muerta

• Vaca Muerta is a regional benchmark for energy sovereignty and economic development.
• GeoPark has completed the acquisition of the Loma Jarillosa Este and Puesto Silva Oeste blocks and has become an operator in a basin with high growth potential.
• The blocks have an initial production of 2,000 barrels of oil equivalent per day and can reach 20,000 barrels per day by 2028.

GeoPark, a leading independent energy company in Latin America, announced the completion of the acquisition of the Loma Jarillosa Este and Puesto Silva Oeste blocks in Vaca Muerta, one of the most prolific and dynamic unconventional formations in the world. Through the operation, GeoPark becomes the official operator of these strategic assets in Argentina and consolidates its growth platform in the region.

The blocks currently produce close to 2,000 barrels of oil equivalent per day and a development plan aims for 20,000 barrels per day by 2028 by drilling 50–55 wells andbuilding a 20,000 barrel per day Central Processing Facility (CPF) as well as an oil pipeline connecting the two blocks, ensuring an integrated and efficient operation.

The development of Vaca Muerta is a regional success story that within 10 years went from being an exploration possibility to producing more than 60% of Argentina’s oil and gas. It enabled Argentina to post an energy sector trade surplus of $5.7 billion in 2024 and is expected to account for over $30 billion of exports by the end of the decade, with accumulated investment of over $47 billion.

In August 2025, Vaca Muerta produced 508,800 barrels of oil per day as Argentina’s total reached 813,096 barrels per day, the highest level since 1999. Vaca Muerta also produced over 160 million m³ per day of gas — four times as much as Colombia — and these statistics demonstrate the basin’s relevance as a Latin America energy engine.

Energy development has directly impacted Neuquén, making it one of the most prosperous provinces in Argentina with a GDP per capita of $61,128, four times higher than the national average. Every direct job in the hydrocarbon industry creates more than five indirect jobs in sectors such as transport, engineering, industrial services and technology.

GeoPark underscores its commitment to the development of Vaca Muerta, contributing its experience in the management of complex assets in different geographies and strengthening its technical capabilities in unconventional assets. The Company’s strategy of protecting its core business and growing in strategic areas seeks to continue creating value for its stakeholders and consolidate its role as a key energy sector player for development in Latin America.
