The next test for US shale capital
Neuquén opens 15 Vaca Muerta block
On 4 May, Gas y Petróleo del Neuquén (GyP) and Governor Rolando Figueroa launched Round 1/2026 at the OTC in Houston, opening 15 hydrocarbon blocks to national and international bidders. The round was formally enacted on 29 May through its publication in the provincial Boletín Oficial, with awards expected before year-end and contract signature in Q1 2027.
The terms have been overhauled. Where prior GyP programs, PNH (2010 to 2017) and PEN (2018 to 2024), prioritised expanding granted surface and broadening the operator base, Round 1/2026 filters for technical and financial capacity.
A $100,000 bid bond per offer, royalty bidding around a 15 % base (effective range 15–18 %), and a coordinated three-bonus structure covering access, commerciality and cession signal a clear shift in how the province is looking to attract new investors. GyP participation is now a competitive variable at 10–20 % per block, effectively a modified carry-across exploration and exploitation.
Offers are scored across sealed technical and economic envelopes, with the most competitive work and royalty proposals winning out.
What is on offer?
The 15 blocks span three clusters, north, centre, and south, all sitting in the liquids window and selected for proximity to existing developments. Sizes range from roughly 50–240 km² (12,355–59,300 acres). Most carry access to existing infrastructure; some remain frontier acreage that will demand patient appraisal before commercial commitment.
A wave of new pipeline and LNG infrastructure, advancing under RIGI, is easing Vaca Muerta’s takeaway risk. New Atlantic oil routes and pipeline expansions could double crude evacuation by 2027, while gas and LNG projects open outlets for production growth.
The timing reflects a deeper recalibration. The old framework was built to attract capital into unproven territory. Vaca Muerta is no longer that. With the play delivering commercial returns at scale, the province is reshaping its terms to match the basin’s momentum and ensure awarded blocks translate into activity on the ground.
What is expected of this round?
Success will be judged on three metrics: How many of the 15 blocks attract offers, the diversity of bidders, and how aggressive the royalty proposals are. A round that brings Permian-focused independents to multiple areas would mark a turning point, confirmation that Vaca Muerta has decisively crossed into mainstream E&P investment.
A thinner outcome, weighted toward local incumbents on adjacent acreage, would suggest the international investor base is still building.
RIGI eligibility ($600 M onshore E&P minimum, 8 July 2027 deadline) is tight given Q4 awards, but not critical. Basin operators advanced projects for years before RIGI’s February 2026 upstream extension, and further support mechanisms for exploration-phase projects are plausible. The consultation window closes on 10 August; bids open on 19 August.
