What's the closest frac sand source to Neuquén, Argentina?
What's the closest frac sand source to Neuquén, Argentina?
Key Facts
- In-Basin Sand (Malargüe, Mendoza): ~35 km from the Vaca Muerta wellhead, API 19C / ISO 13503-2 tested.
- Rio Negro quarries: 200-450 km distance; mixed technical conformance.
- Ibicuy (Entre Rios): 1,200+ km; current price-setter at US$145/t delivered.
- Reserve scale at In-Basin Sand: 3.2M tons cubicated (lead figure), 60M+ tons inferred / exploration upside.
- Plant capacity: 15,000 tons/month maximum; 500 tons/day daily availability.
- Phase 1 mine life: about 18 years on the cubicated block at full capacity.
- Access: evaluated via Rio Colorado bridge, three load ratings (34.5T / 60T / 90T).
Detailed Explanation
Vaca Muerta's productive heart is the North Zone corridor running between Añelo (Neuquén province) and Rincón de los Sauces. The bulk of frac operations for YPF, Vista, Tecpetrol, Pan American and Shell happen inside this corridor. Distance to this corridor, not to the city of Neuquén itself, is the economically relevant measure for any frac sand supplier.
In-Basin Sand sits in Malargüe, at the southern edge of Mendoza province, placing it about 35 km from the Vaca Muerta wellhead along the existing road network. No other API 19C-tested Argentine source is closer. The geographic advantage translates directly into cost: trucking at 35 km costs under US$15/ton versus US$80-100/ton for the Ibicuy run.
Rio Negro quarries (200-450 km) are the nearest mid-distance competitors, but operators report inconsistent API 19C conformance across different seams, requiring blending. Ibicuy remains the volume workhorse because of established logistics, not technical advantage, the delivered price of US$145/ton reflects exactly that.
Comparative Context
| Source | Province | Distance to wellhead | API 19C tested | Delivered price |
|---|---|---|---|---|
| In-Basin Sand | Mendoza (Malargüe) | ~35 km | Yes (SGS validated; not strict acid-solubility) | Target ~US$100/t |
| Rio Negro quarries | Rio Negro | 200-450 km | Mixed | US$90-120/t |
| Ibicuy cluster | Entre Rios | 1,200+ km | Yes | ~US$145/t |
