TOUGH2 Example Problems

Download the TOUGH2 example manual. This manual includes detailed step-by-step instructions using PetraSim to run TOUGH2 example problems.

• Five Spot Geothermal Production and Injection (EOS 1). Problem 4 in the TOUGH2 user’s manual. Input and results files.

• 3D Contoured Top (EOS 1). Demonstrates use of a contour file to define the geometry of the surface of the reservoir. It also
  demonstrates a two part analysis, with an initial state calculation followed by a production analysis. Initial state input and results.  Well table data for the production analysis. Production input and results.

• Heat Sweep in a Vertical Fracture (EOS 1). Problem 3 in the TOUGH2 user’s manual. Steady state input and results. Transient input and results.

• Heat Pipe in Cylindrical Geometry (EOS 3). Problem 2 in the TOUGH2 user’s manual. Input and results files.

• Variable Salinity Problem (EOS 7). Problem 6 in the TOUGH2 user’s manual. Input and results files.

• VOC Contamination (EOS7R). Demonstrates the use of extra cells, modeling of an atmospheric boundary condition, and establishing an initial gravity/capillary equilibrium condition. Problem 8 in the TOUGH2 user’s manual. Initial state and transient files.

• Production from Geothermal Reservoir (EWASG). Problem 12 in the TOUGH2 user’s manual. Input and results files.

T2VOC Example Problems

• 1D Gas Diffusion of an Organic Compound. Problem 1 in the T2VOC user’s manual.

• 2D Steam Replacement of NAPL. Problem 4 in the T2VOC user’s manual.

• 3D Steam Replacement of NAPL. 3D variation of problem 4 in the T2VOC user’s manual.
