- •
Permeability enhancement/hydraulic fracturing is introduced in a thermo-poroelastic framework.
- •
A fracturing model is defined to calculate fracture size and aperture in all directions of space.
- •
An anisotropic fracture-induced permeability tensor is calculated at each point in the computational grid.
- •
The fully integrated framework of hydraulic fracturing in thermo-poroelasticity is coded using FOR- TRAN 90.
- •
Circulation tests and thermal recovery from the geothermal reservoir of Soultz-sous-Forêts are sim-ulated.
