GeoPark wins Corralera Noreste block in Vaca Muerta licensing round with $95 million commitment
GeoPark just picked up a new block in Argentina’s Vaca Muerta formation. The company won the Corralera Noreste acreage through Neuquén Province’s Ronda 1/2026 licensing round, run by provincial energy company Gas y Petróleo del Neuquén. The block sits near Rincón de los Sauces, in the northern part of the Vaca Muerta trend, and adds roughly 26,900 gross acres to GeoPark’s existing portfolio in one of South America’s busiest shale plays.
GeoPark secures Corralera Noreste block through provincial bid round
Gas y Petróleo del Neuquén — GyP for short — runs licensing activity across the province and managed this round from start to finish. Neuquén is one of Argentina’s most productive hydrocarbon provinces, and the round drew competitive interest from operators looking to get in or expand their footprint in Vaca Muerta.
Corralera Noreste sits near Rincón de los Sauces, a northern Vaca Muerta town that’s been attracting more operator attention over the past few years. The block totals roughly 26,900 gross acres, or about 24,200 net acres. For a company already active in the basin, that’s a meaningful land addition — not a minor footnote.
GeoPark has also identified two additional prospective horizons beyond those initial zones, representing further upside that sits outside the core estimate for now.
Total commitment of $95 million vovers entry bonus and initial appraisal vosts
GeoPark’s total committed cost for the block comes to approximately $95 million, covering both the entry bonus to secure the award and the costs tied to the initial appraisal program.
There’s no full-scale development commitment upfront. Instead, the company plans to move through appraisal in stages — a structure that limits financial exposure while the block’s actual potential is still being worked out. It’s a measured approach, and it makes sense given the size of the resource estimate on the table.
What happens beyond that $95 million depends entirely on what the appraisal program finds. Technical results and project economics will drive those future calls. GeoPark hasn’t put a number on what full development might eventually look like, and that’s deliberate — the phased structure is designed to keep options open.
Appraisal program to begin with two horizontal wells and extended production testing
The first phase at Corralera Noreste means drilling and completing two horizontal wells. Once those are in place, GeoPark will run extended production testing to get a real read on productivity and resource quality across the block.
The company estimates 200 MMboe of unrisked gross resource potential, based on two primary landing zones in the formation. That’s a big number — but “unrisked” is the key qualifier. It reflects theoretical potential before technical and commercial risks are factored in. GeoPark has also identified two additional prospective horizons beyond those initial zones, representing further upside that sits outside the core estimate for now. Whether the company pursues them will depend on what those early wells show.
Potential peak production of Up to 50,000 boe/d contingent on successful development
If appraisal goes well, GeoPark sees potential gross peak production from the two initial landing zones reaching between 40,000 and 50,000 barrels of oil equivalent per day. A notable ceiling — though the company frames it clearly as conditional on successful appraisal and development outcomes.
The block also deepens GeoPark’s existing presence in Vaca Muerta more broadly. Recognized as one of the largest shale oil and gas accumulations in the world, the formation has become a central focus for energy investment in Argentina. Operators from multiple countries have moved into the play over the past decade, drawn by its scale and the improving economics of horizontal drilling and completions.
Adding acreage in the northern trend gives GeoPark more room to build out its Vaca Muerta strategy. Corralera Noreste sits in a part of the play drawing growing attention, and its proximity to Rincón de los Sauces means existing nearby infrastructure could eventually support development work.
What the Corralera Noreste award means for GeoPark
Here’s where things stand: GeoPark won Corralera Noreste through Neuquén Province’s Ronda 1/2026 round, adding roughly 26,900 gross acres in the northern Vaca Muerta trend. Total committed cost sits at approximately $95 million, covering the entry bonus and the initial appraisal phase.
Appraisal starts with two horizontal wells and extended production testing. GeoPark estimates 200 MMboe of unrisked gross resource potential across two landing zones, with two additional horizons offering more upside beyond that. Peak gross production from the initial zones could reach 40,000 to 50,000 boe/d — if the wells perform and development moves forward as hoped.
The phased structure keeps near-term exposure manageable while leaving room to scale up if results justify it. For now, the focus is straightforward: get those first two wells drilled and find out what the block can actually deliver.
