TOUGH History

Historical Overview of TOUGH Simulators

 

Simulator Description Released Key Reference
TOGA Released for licensing. TOGA (TOUGH Oil, Gas, Aqueous) is a numerical reservoir simulator for modeling non-isothermal flow and transport of water, CO2, multicomponent oil, and related gas components for applications including CO2-enhanced oil recovery (CO2-EOR) and geologic carbon sequestration in depleted oil and gas reservoirs. 2020 Pan and Oldenburg, 2020
toughio Authorized for distribution. toughio is an open-source library that provides tools to facilitate pre- and post-processing for TOUGH using the latest Python standards. It aims to make setting up of a TOUGH simulation user-friendly by relying on existing well-established Python packages, namely numpy, meshio and pyvista (Link to toughio documentation). 2020 visit site
TOUGH3 TOUGH3 replaces TOUGH2 in the TOUGH family of codes. TOUGH3 consolidates more than a decade of independent developments of the TOUGH codes by multiple researchers, including the massively parallel version TOUGH2-MP, into a single flagship simulator coded in FORTRAN90 capable of exploiting multi-processor machines. While TOUGH3 has significant coding changes to facilitate parallel execution particularly in parts of the code related to linear equation solution, experienced TOUGH2 users will find familiar subroutine names and FORTRAN code in the subsurface process (e.g., flow, transport, phase equilibria, capillary pressure, etc.) subroutines which remain relatively unchanged from the originals developed by Karsten Pruess and others over the last several decades. 2019 Jung et al., 2018
