Loma Campana is the flagship unconventional development of Vaca Muerta — a 50-50 joint venture between YPF and Chevron, operational since 2013 and still among Argentina's most prolific shale oil producing blocks. Per Argentine Oil Secretariat data, hundreds of horizontals have been completed on the block to date, and development continues. Every completion consumes API 19C proppant. In-Basin Sand sits 30 km from the Loma Campana logistics gate.
Loma Campana lies immediately west of Añelo, Neuquén — the physical centre of the Vaca Muerta oil-window development. Proppant arrives by truck. Today most of that truckload freight begins on a barge at Ibicuy (Entre Ríos), then transfers to long-haul trucks for the final leg. A Malargüe origin eliminates the barge leg entirely.
| Source | Distance to Loma Campana | Delivered price |
|---|---|---|
| In-Basin Sand (Malargüe) | ~30 km | ~US$100/ton |
| Ibicuy (Entre Ríos) | ~1,400 km | US$140/ton |
| Río Negro regional suppliers | 200–400 km | US$90–120/ton |
Loma Campana's horizontals typically consume +30/+70 mesh for primary proppant and -70/+140 for near-wellbore placement. In-Basin Sand produces both cuts under API 19C, validated by SGS Minerals (Chile). Crush resistance, roundness and turbidity all in spec.
In-Basin Sand's operating team submitted a 10,000 t/month take-or-pay proposal to Chevron procurement in 2023. No contract was signed. Conversations are reconnecting under NDA for the 2026–2027 cycle.
The plant's 15,000 t/month capacity maps well to a single-pad dedicated program on Loma Campana, or a combined YPF + Chevron supply carve-out in the broader block. Mine life at full throughput is 37+ years.
