TReactMech V1.0 is a new 3-D coupled thermal-hydrological-mechanical-chemical (THMC) code that solves the continuum geomechanical stress and failure equations using a finite element formulation coupled to non-isothermal, multiphase/multicomponent fluid flow, heat transport, aqueous and gaseous species advection-diffusion, and equilibrium/kinetic water-gas-rock reactions. TReactMech combines a new geomechanics approach with the latest TOUGHREACT V3.30-OMP multiphase reactive-transport capabilities. Notable applications of TReactMech V1.0 are in the simulation of coupled THMC processes in Enhanced Geothermal Systems, geological CO2 sequestration, hydraulic fracturing in unconventional hydrocarbon reservoirs, nuclear waste isolation, injection/production-induced uplift/subsidence, and other subsurface problems involving geomechanical, hydrological, and geochemical processes. A wide range of spatial and temporal scales can be modeled from fracture deformation in lab experiments, hydraulic fracturing at scales of tens of meters around injection wells, to complex kilometer-scale problems involving hydrological, mineralogical, and chemical heterogeneity and crustal heat and fluid flow over geologic time scales. The course will focus on the basic formulations used in TReactMech, including poroelasticity, Mohr-Coulomb failure, and coupling of geomechanics to fluid pressure, heat transport, and fracture permeability changes. Hands-on example problems will focus on the set-up of hydro-geomechanical problems, stress-strain simulations involving poroelasticity, injection-induced fracture shear and tensile failure, and simple reactive-transport coupling. Pre-requisites include prior experience or courses in TOUGH2 or TOUGHREACT.
