Define oil and water production rate for cells

We are using EOS8 modulus to simulate a reservoir with oil and water 2 phases. For the production well, there are oil and water production. How do we define the oil and water rate for the…

lacking of continuous column of CO2 from the injection point to the caprock in a sandstone reservoir model

Hi, I am injecting CO2 in a high porosity and permeability sandstone reservoir during a period of 30 years. It is an isothermal model. I have a problem with the CO2 plume.…

MINC and low permeability case problem in Tough2

Hi All, I set up a case using the MINC with 2 continua. The first continua represents the fracture and the second one represents the matrix. For this case,…

Do you have a recommended module to simulation gas condensate reservoir?

It's a deep gas condensate reservoir, what's module is good for it? What about EOS7C? Thank you very much

Hi everybody, I have a question regarding a particular simulation (I am using Petrasim). Can you help me?

Hi everybody, I have a question regarding a particular simulation (I am using Petrasim). Can you help me? I am trying to simulate the heat and fluid flow within a volcanic edifice.…

Gas relative permeability: equation ???

Hello everybody, I have one question regard the document Tough v2, in "tough v2.0 manual" , we assume krg=1-krl if Sgr=0, we found that this is very strong assumption and which is not confirmed by…

Error on installation

I'm trying to install TOUGH2 for EOS2 and I'm having trouble in the compilation. I'm not sure if the code is right and when I type it, I receive this message.…

Oil relative permeability in EOS8

Hi All, I am trying to set up the input file for EOS8 module to run a water flooding oil case. As from the manual, the oil relative permeability is set to be linear with respective to oil saturation…

A problem with my simulation with EOS9nT

I have some problems in my modelling project with EOS9nT. In my example I want to simulate the nuclide release and transport process in a disposal site with a 3-D model.…

MINC Varying Fracture Spacing

After reading the manual, I can't tell if it is possible to vary the fracture spacing between different gridblocks using MINC in TOUGH2. Is there a way to do that? Thanks, John

Making input file

Hi all I am pretty new to TOUGH code and my domain problem is trapezoid. Actually, it is hard for me to make my input file boundary in notepad manually.…

Suggestion in change the GENER
