Vaca Muerta from Mendoza: What You Need to Know to Operate in the Neuquén Basin

Vaca Muerta is the country's largest logistics demand

The Vaca Muerta formation occupies approximately 30,000 km² in the Neuquén subsoil and is the second-largest unconventional gas and fourth-largest unconventional oil reserve in the world. Its development requires a logistics chain that never stops: thousands of trucks a month, millions of tons of supplies and a coordination that combines speed with precision.

From Mendoza, the corridor to Neuquén is one of our most frequent routes. In this article we tell you what you need to know to operate.

The Mendoza–Neuquén corridor: key facts

• Distance: ~630 km from Maipú to Neuquén City
• Estimated transit: 7 to 9 hours depending on the specific destination
• Main route: RN 40 to Neuquén, then detours by pad zone
• Most frequent destinations: Añelo (~8 hrs), Rincón de los Sauces (~10 hrs), Loma Campana (~8.5 hrs)

Route 40 on the Mendoza–Neuquén stretch is fully paved and one of the highest-traffic routes in northern Patagonia. Under normal conditions, it is a reliable and predictable corridor.

What moves from Mendoza to Vaca Muerta

Frac sand (proppants)

It is the highest-volume input in the basin. Each unconventional well can consume between 800 and 1,500 tons of frac sand. Operators work with very tight time windows: the sand delivery has to arrive at the exact moment the fracking crew needs it.

From Mendoza we operate with frac-sand plants to the Añelo and Loma Campana pads at high frequency. It is a service where the carrier's reliability is worth more than the price.

RMI — Rig Move (dismantle, transport and assemble)

Drilling rigs and workover equipment move between pads. An RMI is a highly complex operation: the pieces are oversized, the timing is critical (every idle day has an enormous cost for the operator) and the coordination requires real experience.

For each RMI we do a specific assessment: route, permits, necessary escorts and coordination with the operator for the assembly times.

Hydraulic fracturing chemicals — ADR/IMO

Acids, inhibitors, gelling agents and biocides travel under ADR/IMO classification (dangerous-goods transport). Not just any truck can carry them: the vehicle must have the specific authorization, the driver must have a valid hazardous-materials (MATPEL) certification, and the documentation must be flawless.

We hold the current authorizations for this type of cargo. The documentation and safety protocol are integrated into the process from the start.

Housing modules for camps

Camps in the Neuquén basin are set up and dismantled constantly. Moving housing, sanitary and office modules between locations is a logistics operation that requires oversized-load permit coordination and field-assembly experience.

Authorizations you need to verify

If you are going to operate in Vaca Muerta —whether as an operator, service company or logistics provider— these are the authorizations you need to review:

• CNRT: national authorization for general and special cargo transport
• RUCA: enabling registry for the carrier company
• ADR/IMO: for dangerous goods (chemicals, fuels, flammables)
• Neuquén provincial authorizations: some site access routes require specific provincial authorization
• Entry protocols for each operator: YPF, Shell, Chevron and others have their own HSE requirements for vehicles and drivers entering their facilities

At Rutas del Sur we keep these authorizations up to date. For new clients who hire us to operate in the basin, we can support them in managing the entry documents.

The most common mistake: underestimating preparation times

Many projects fail in logistics not because the truck arrives late, but because the preparation took longer than expected.

The times to consider in Vaca Muerta:

• Oversized-load permits: can take 3 to 7 business days depending on the province and cargo type
• ADR documentation: must be ready before loading, not after
• Coordination with the operator: most require 24 to 48 hours' prior notice for entry to the location
• Pad operating windows: you cannot always arrive when you want — the pad has its own timing

For high-frequency operations (sand supply, drilling-campaign inputs), advance planning with the carrier makes it possible to guarantee precise delivery windows.

Why Mendoza is a strategic node for Vaca Muerta

The Neuquén basin is supplied from multiple points in the country, but Mendoza has specific advantages:

• Shorter distance than from Buenos Aires (~580 km closer)
• Direct connection to industrial-input suppliers
• Access to RN 40 without passing through congested areas
• The ability to coordinate return loads (wine, fruit, various supplies) to reduce costs

For companies with operations in both Mendoza and Neuquén, Rutas del Sur can operate the full corridor in both directions.
