GeoPark starts drilling the Loma Jarillosa Este block in Vaca Muerta

The Company starts its first Vaca Muerta drilling campaign in its Argentina work plan, in which investment will be US$80-100 million in 2026.

GeoPark announces the start of drilling operations in the Loma Jarillosa Este block, targeting the Vaca Muerta formation in Neuquén province. This milestone is a decisive step in the Company’s accelerated growth plan in Argentina and consolidates its position as one of the leading new operators in the Neuquén Basin. To carry out the campaign GeoPark is working with over 30 contractors in different service specialties through 40 contracts, positively affecting the local and regional value chain.

The Company has allocated US$80-100 million in 2026 to develop Loma Jarillosa Este and multiply its production in Argentina by 3 or 4 times from 1,500 barrels of oil per day to 5,000-6,000 barrels per day by year-end. The ambitious medium-term plan is for a tenfold production increase in three years, reaching 20,000 barrels per day by end-2028.

“Vaca Muerta is one of the most dynamic unconventional plays in the world and we are building a position here that will be central to GeoPark’s regional portfolio. This asset is redefining our scale as a Company, consolidating GeoPark as a relevant operator in Vaca Muerta by creating a profitable and sustainable long-term production platform. Every well we drill brings us closer to that goal,” GeoPark Argentina’s Country Director Ignacio Mazariegos said.

GeoPark has already opened an office in Neuquén – where a 30-strong local team continues to grow in line with operations – and has taken one of its first corporate social responsibility steps by contributing US$250,000 to the Gregorio Álvarez Scholarship program in recognition of the importance of education to Neuquén’s sustainable development. The Company highlights the support received from provincial authorities, which has been key to meeting the demanding operational schedule.

Starting drilling underscores GeoPark’s commitment to Argentina as one of its main growth focuses, bringing investment, employment and technological development to the heart of Vaca Muerta.
