Thermal Compositional Simulator

Thermal Compositional includes temperature in compositional simulations and is typically used for hot water and steam injection simulations. Input data from some third party thermal decks are supported. This module can be used with Graphical Interface module or separately as a console version on the workstation or cluster.

  • K-values for hydrocarbon components via tables or via correlation formulas (surface).
  • Four phases: oil (hydrocarbon components), gas (hydrocarbon components, water), water and the solid phase. Phase transitions: evaporation, condensation, dissolution, combustion, modeling of chemical reactions.
  • Support for solid phase and chemical reactions for in-situ combustion process.
  • Equilibrium and nonequilibrium initialization.
  • Porosity dependence on temperature and pressure.
  • Liquid phases individual component densities, viscosities as functions of temperature and pressure.
  • Enthalpies of hydrocarbon components and rock as functions of temperature.
  • Relative permeabilities scaling with respect to composition and temperature.
  • Analytical, semi-analytical and numerical aquifers.
  • Analytical model of heat exchange with the environment.
  • Thermal conductivity dependence on conductivities of mobile phases, solid phases and rock.
  • Electrical heaters.
  • Dual porosity, dual permeability options.
  • Steam injection, mixture injection, multicomponent and multiphase streams, WAG.
  • Steam Assisted Gravity Drainage technology (SAGD).
  • Using CPU+GPU processors, clusters for faster calculation.
  • Reservoir coupling.

Fully Coupled Geomechanics Simulations

tNavigator uses a joint system of coupled equations to describe filtration processes in the reservoir and geomechanical effects on the unified grid.

  • The same model grid is used for reservoir dynamic and geomechanic simulations (block centers for reservoir simulations, block corners for geomechanics).
  • Joint system of coupled equations is solved numerically in a parallel way: geomechanics (only CPU cores), reservoir dynamics (CPU and GPU cores).
  • All model types (black oil, thermal, compositional) are supported.
  • Young’s modulus, Poisson constant, boundary condition for stress, boundary condition for displacement.
  • Modeling of geomechanical effects via hysteresis rock compaction data tables.
  • Mohr-Coulomb failure criterion is used for analysis of stress state and predict the potential rock fault. Possible fracture directions.
