ECO2M: Injection under injection-pressure constraint
Hello, I'm running ECO2M to simulate a CO2 injection. Does anyone know if it's possible to simulate the injection under a bottomhole-injection constraint, instead of injection rate constraint?…

Mass balance of ECO2N
I was simulating constant CO2 injection into a 2D aquifer (salt not considered). For such 2-phase 2-component system, there should be 2 mass balance equations for CO2 and H2O, respectively,…

Numerical instabilities introduced after printout
I'm running a simulation with intermittent printouts using TOUGH3. I noticed that, after some of those printouts, numerical instabilities are seemingly introduced that stall the remainder of the run.…

Simple model test with ECO2N
I was testing the ECO2N module compiled by myself (Linux version). I built a simple model with 2 grids. I set pressure difference of 2MPa and gas saturation difference of 0.…

Drastic fluctuation of pressure vs. time curve
Hi, I simulated a simple model with EOS1, but I got a strange pressure vs. time curve. What may causes the curve fluctuation? The ground water velocity is 10-7 m/s, the production rate is 150 m3/h.…
