Hydrate Modeling - TOUGH+/HYDRATE & HydrateResSim

TOUGH+/HYDRATE v1.0

LBNL's new hydrate reservoir simulator (TOUGH+/HYDRATE v1.0) is now publicly available for licensing. TOUGH+/HYDRATE models non-isothermal gas release, phase behavior and flow of fluids and heat in complex geologic media. The code can simulate production from natural CH4-hydrate deposits in the subsurface (i.e., in the permafrost and in deep ocean sediments), as well as laboratory experiments of hydrate dissociation/formation in porous/fractured media. TOUGH+/HYDRATE v1.0 includes both an equilibrium and a kinetic model of hydrate formation and dissociation.

Also available is HydrateResSim. HydrateResSim (HRS) is a freeware, open-source reservoir simulator code available for use “as-is” from the NETL. HRS’ code was derived from an earlier version of the TOUGH+/Hydrate code.

 

code comparison study is currently being conducted to compare various hydrate reservoir simulators. Graphic comparisons of the models' outputs and the test problems are included.

HydrateResSim

HydrateResSim (HRS) is a freeware, open-source reservoir simulator code available for use “as-is” from the NETL. The HRS code was derived from an earlier version of the TOUGH+/Hydrate code. NETL makes no guarantees as to the compatibility or functionality of HRS with different computing systems, compilers, etc.

 

The HydrateResSim code is available as a .zip file. To receive this file please e-mail james.dean@netl.doe.gov  

 

code comparison study is currently being conducted to compare various hydrate reservoir simulators. Graphic comparisons of the models' outputs and the test problems are included.

 

Some of the key features shared by TOUGH+/Hydrate and HydrateResSim:

 

  • Both include an equilibrium and kinetic model of hydrate formation and dissociation,
  • Account for heat and up to four mass components (i.e., water, CH4, hydrate, and water-soluble inhibitors such as salts or alcohols),
  • Include four possible phases (gas, liquid, ice, and hydrate), and
  • Can describe various hydrate dissociation mechanisms (i.e., depressurization, thermal stimulation, salting-out effects, and inhibitor-induced effects).
