STOMP software is a collection of computer models (or "simulator modes" or "simulators") that numerically simulate multifluid subsurface flow and reactive transport processes. The simulators are specifically designed to provide scientists and engineers from varied disciplines with multidimensional capabilities for addressing a variety of subsurface environments, including nonisothermal conditions, variable saturations, phase transitions, nonwetting fluid entrapment, freezing conditions, hydrate formation and dissociation, and reactive systems.

Currently the STOMP software has the following operational simulator modes:

STOMP-W (Water Operational Mode)
STOMP-W-R (Water Operational Mode w/ ECKEChem Module)
STOMP-WAE (Water-Air-Energy Operational Mode)
STOMP-WAE-B (Water-Air-Energy Operational Mode w/ Surface Barrier Module)
STOMP-WO (Water-Oil Operational Mode)
STOMP-WOA (Water-Air-Energy Operational Mode)
STOMP-LGE (Aqueous-Gas-Energy Operational Mode, multicomponent, nonisothermal)
STOMP-LN (Aqueous-NAPL Operational Mode, multicomponent, isothermal)
STOMP-LGN (Aqueous-Gas-NAPL Operational Mode, multicomponent, isothermal)
STOMP-CO2 (Geologic Sequestration in Saline Reservoirs Operational Mode, isothermal)
STOMP-CO2-R (Geologic Sequestration in Saline Reservoirs Operational Mode, isothermal, optional ECKEChem Module)
STOMP-CO2e (Geologic Sequestration in Saline Reservoirs Operational Mode, nonisothermal)
STOMP-CO2ae (Geologic Sequestration in Saline Reservoirs Operational Mode, air component, nonisothermal)
STOMP-HYD (Gas Hydrate Operational Mode, nonisothermal, optional CO2 and N2, optional inhibitor)

Additional simulator modes are either under development, or planned for development over the next 3 years:
