JT Heat exchange in the cell containing well (using ECO2N)
Hello guys, In a non-isothermal run with gas (CO2) injection into an aquifer conditioned within supercritical domain of CO2, you expect some heating from compression and some cooling from expansion.…

The extent of CO2 injection cooling using ECO2N
Hi all, Aiming at thermal QC of another code by using Tgh2-ECO2N, I made a simple coarse model with dimension 25x5x100 where dx=dy=200m and dz=4m, por & perm were 0.…

Residual and solubility trapping
Hello everyone. I am working on Co2 storage using both ECO2N answer ECO2M. In the result we have 1-sg which represents the saturation of CO2 in gas phase.…

Pore Compressibility in ECO2M
Hi guys, I have a 3D cartesian model where I assign constant porosity across all elements in the model. In TOUGH2, I think we can assign only a constant value of pore compressibility.…

Constant gas production rate
We are using EWASG modulus to simulate a reservoir with water, salt, and NCG. For the production well, there are water and NCG production. We know that we can set total (gas + liquid) production…
