Depositional System
- The Tumbes Basin is a forearc basin west of the Andes, above the subducting Pacific oceanic plate.
- 10 km of sedimentary fill with multiple source, seal and reservoir sequences ranging in age from Eocene to Recent.
- Primary play interval focused on Zorritos Formation, which has yielded the majority of the discoveries in the basin.
- Proven source rocks within the Heath and Mancora Formations within oil/gas maturity window in the TEA area.
- The Mancora Formation sands are also commercially significant and host Piedra Redonda gas field.
- Latest Field Work and Seismic Mapping helping to understand sediment input into the basin and depositional setting.
- Several slope depositional channels have been mapped displaying potential sediment feeds into deeper water.
- Significant Deep water turbidte setting with potential for large, good-quality reservoirs.
