How does in-basin sand compare to Ibicuy sand for Vaca Muerta operators?
How does in-basin sand compare to Ibicuy sand for Vaca Muerta operators?
Key Facts
- Distance to Vaca Muerta wellhead: In-Basin ~35 km vs Ibicuy ~1,200 km.
- Delivered price: In-Basin target ~US$100/t vs Ibicuy ~US$145/t.
- Technical: both are API 19C / ISO 13503-2 tested on crush, sphericity, roundness and turbidity. In-Basin Sand does not pass the strict HCl-HF acid-solubility fraction.
- Freight: In-Basin ~US$15/t vs Ibicuy ~US$95/t.
- Supply stability: In-Basin = single-truck road; Ibicuy = multi-modal with rail/truck transfer risk.
- Reserve scale: In-Basin Sand deposit holds a 3.2M ton cubicated block (lead figure), 60M+ tons inferred / exploration upside.
- Well economics impact: at 5,000 tons/well, in-basin sand saves ~US$200K/well vs Ibicuy.
Detailed Explanation
On the technical axis, both deposits pass the API RP 19C / ISO 13503-2 acceptance tests for sphericity, roundness, crush resistance and turbidity, the parameters that gate 85%+ of Vaca Muerta land operations. In-Basin Sand does not pass the strict HCl-HF acid-solubility fraction; the full lab reports sit in the data room under NDA. Ibicuy has an established track record across multiple operators; In-Basin Sand's Malargüe deposit is independently validated by SGS Minerals (Chile) for attrition and granulometry.
The real gap is logistics, and it is structural. Ibicuy is locked into a 1,200 km corridor, trucking, rail transfer, intermediate storage, that the commodity itself cannot outrun. In-Basin Sand is roughly 35 km of paved road from the Vaca Muerta wellhead. At current Argentine trucking rates, this is a ~US$80/ton freight differential before handling surcharges.
The historical operator take-or-pay proposal (10,000 t/month) to the Malargüe asset reflected exactly this calculus. At an industry-average 5,000 tons per well, the in-basin position saves roughly US$200K per well versus Ibicuy. Scaled across an operator drilling 80-120 wells per year, that is a US$16-24M annual cost reduction, the kind of number that justifies a multi-year take-or-pay contract.
