Industrial grade reservoir simulators like IMEX/ECLIPSE/INTERSECT/... are probably unsuited for the type of work you want to perform. You likely need to access and tweak the physical engine of the simulator. R&D codes are what you are looking for. Some source code, which allows you to tweak physics at core, are open source. Google MRST, ADGPRS, OPENFOAM, etc. I would expect some tweaks to be already available in those codes. This will require some investment on your side into the selected code. It is probably advisable that you select one that is used by people around you.

A very crude alternative is to tweak an industrial grade simulator with restarts or use some of the options that exist in some of those "a little bit far". But this is very crude and messy, I would not recommend that.

Hi Pierre Bergey, thanks for the feedback.

I already look into the open source R&D software as you mentioned above.

Agree with you that restarts or tweaking the industrial grade simulator will not be an option.

I will stick with MRST by SINTEF then even though it will take lots of time as well.

Thanks again

Hi Madhan,

I guess you mean flow diversion in the macroscale sense, not on the pore-scale.

MRST does the trick, though the degree of diversion will be highly dependent on many other factors... as a matter of fact, I believe total diversion is highly unlikely to be observed. I had an implementation on top of their polymer solver that was changing the permeability due to retention of particles.

It is not a hard work, you just need to make sure to update the rock properties every time a time step is taken.

Good luck

Hi Max Endo,

Exactly that's what I mean. I want to model it in the macroscopic-scale. You mentioned about other factors affecting diversion. Where can I further study on that factors? Do you have good references on that?

Actually changing rock properties (permeability) every time step that's what I called "Dynamic Permeability Model" however it is not so convenience in the CMG.

I am going to try in MRST, but the question is it possible to tune up the program by adding loop for dynamic permeability correction?

Thanks Max

On top of the head I don't remember any reference, but I can take a look and come back later.

About MRST: yes, it is possible. You just need to update rock properties and then recalculate the operators (transmissibilities, mostly). In the end you just need to add three of four lines into the equations file.

Regards,

Cut time step --> update permeability model each step --> initiate with previous condition --> re-run simulation.
