DescriptionPetraSim is the graphical interface for the TOUGH2 family of simulators. Developed at Lawrence Berkeley National Laboratory, TOUGH2 and its derivatives are recognized for their powerful simulation capabilities for fluid flow and heat transfer in porous and fractured media.
The TOUGH2 codes have been applied to problems ranging from Yucca mountain groundwater flow to multi-component environmental remediation.
PetraSim makes the power of TOUGH2 accessible to modelers through an interactive 3D environment that includes mesh generation, parameter definition, and display of results.
PetraSim significantly lowers the barriers to TOUGH2 use by freeing the analyst to focus on the model, while automatically handling the complex details of TOUGH2 input and output files.
PetraSim includes TOUGH2, T2VOC, TMVOC, and TOUGHREACT executables.

TOUGH2 is a general-purpose numerical simulation program for multi-phase fluid and heat flow in porous and fractured media. It belongs to the MULKOM family of codes, developed in the Earth Sciences Division of Lawrence Berkeley National Laboratory for applications in geothermal reservoir engineering, nuclear waste disposal, and unsaturated zone hydrology.
TOUGH2-MP is a massively parallel (MP) version of the TOUGH2 code, designed for computationally efficient parallel simulation of isothermal and nonisothermal flows of multicomponent, multiphase fluids in one, two, and three-dimensional porous and fractured media. In recent years, computational requirements have become increasingly intensive in large or highly nonlinear problems for applications in areas such as radioactive waste disposal, CO2 geological sequestration, environmental assessment and
remediation, reservoir engineering, and groundwater hydrology. The primary objective of developing the parallel-simulationcapability is to significantly improve the computational performance of the TOUGH2 family of codes. The particular goal for the parallel simulator is to achieve orders-of-magnitude improvement in computational time for models with ever-increasing complexity.
EWASG (included in the TOUGH2/T2VOC module) has been developed within the frame of a collaboration among Aquater SpA, an engineering services company of the Eni Group (now incorporated into Saipem SpA), the International Institute for Geothermal Research (IIRG) (now incorporated into the Institute of Geosciences and Earth Resources (IGG) of the National Research Council of Italy (CNR)) and the Earth Sciences Division (ESD) of Lawrence Berkeley National Laboratory (LBNL). Geothermal fluids usually consist of complex mixtures of water, salts and gases. As the thermodynamic and transport properties of such mixtures affect reservoir conditions and performance, the EWASG (Equation-of-state for WAter, Salt and Gas) module has been developed for the TOUGH2 multipurpose numerical reservoir simulator to handle three-component fluid mixtures of water, sodium chloride and a slightly soluble non-condensible gas (NCG).
T2VOC is a TOUGH2 module for 3-phase flow of water, air, and a volatile organic compound (VOC). T2VOC was designed to simulate processes such as the migration of hazardous non-aqueous phase liquids (NAPLs) in variably saturated media, forced vacuum extraction of organic chemical vapors from the unsaturated zone (soil vapor extraction), evaporation and diffusion of chemical vapors in the unsaturated zone, air injection into the saturated zone for removal of volatile organics (air sparging), direct pumping of contaminated water and free product, and steam injection for the removal of NAPLs from contaminated soils and aquifers.
TMVOC is a numerical simulator for three-phase non-isothermal flow of water, soil gas, and a multicomponent mixture of volatile organic chemicals (VOCs) in multidimensional heterogeneous porous media. It is an extension of the TOUGH2 general-purpose simulation program developed at the Lawrence Berkeley National Laboratory. TMVOC is designed for applications to contamination problems that involve hydrocarbon fuel or organic solvent spills in saturated and unsaturated zones. It can model contaminant behavior under "natural" environmental conditions, as well as for engineered systems, such as soil vapor extraction, groundwater pumping, or steam-assisted source remediation.
TOUGHREACT is a new extension of TOUGH2 that couples chemical reactions to fluid flow. Coupled modeling of subsurface multiphase fluid and heat flow, solute transport, and chemical reactions can be used for assessment of waste disposal sites, acid mine drainage remediation, contaminant transport, groundwater quality, CO2 sequestration, and mineral alteration in geothermal systems. TOUGHREACT can be applied to porous and fractured media with physical and chemical heterogeneity. The model can accommodate any number of chemical species present in liquid, gas, and solid phases. A variety of equilibrium chemical reactions are considered, such as aqueous complexation, gas dissolution/exsolution, and cation exchnage. Mineral dissolution/precipitation can proceed either, subject to local equilibrium or kinetic conditions. Changes in porosity and permeability due to mineral dissolution and precipitation can be considered.
TOUGH-Fx/HYDRATE v1.0 is a new code, developed by LBNL, that simulates the behavior of hydrate-bearing geologic systems. By solving coupled equations of mass and heat balance, TOUGH-Fx/HYDRATE can model the non-isothermal gas release, phase behavior and flow of fluids and heat under conditions typical of common, natural CH4-hydrate bearing deposits (i.e., in the permafrost and in the deep ocean sediments) in complex formations.
