The ECO2N (TOUGH2 and TOUGHREACT) and ECO2M (TOUGH2) simulators supported by PetraSim are widely used to simulate subsurface CO2 sequestration in saline aquifers by modeling physical, residual , solubility and mineral trapping of injected CO2 in sub and super-critical conditions.
- Use PetraSim to create radial or three dimensional TOUGH2 meshes representing cap rocks and reservoirs with heterogeneous properties.
- Import conceptual model layers using xyz ASCII file or using GRDECL files exported from Petrel or other modeling packages.
- Assign material properties to each conceptual model layer, or assign cell-based Permeability and Porosity values to represent heterogeneous materials.
- Create vertical or deviated injection wells using the interface or by importing an ASCII file containing data for multiple wells.
- Graphically display changed in gas saturation and dissolved CO2 over time.
- Use TOUGHREACT and PetraSim to model and visualization water-rock reactions, including changes in porosity caused by CO2 injection.
