Re: Initial Geochemical Equilibrium between Minerals and Brine Thanks again, Lennard. The mineral assembly was measured for our rock sample, which is why I would like to stick to it. Indeed there are uncertainties associated with the measurements.…

Initial Geochemical Equilibrium between Minerals and Brine
Hello there, I'm simulating CO2 injection into sandstone aquifer of synthetic brine, NaCl. I've read in several papers in which TOUGHREACT w/ ECO2N is used and something is mentioned like "batch…

Boundary water
Hi all, I'm modeling CO2 underground injection and we are injection a mixture of brine and supercritical CO2. Under the system pressure and temperature and the injection rates,…

Re: Prescribed boundary conditions for chemistry but constant flow rate BCs for flow Nic, Thanks for your answer. What you suggested is what I did in the input files. I also tried to assign the boundary water to only the injection cell in the Record_15.…

Prescribed boundary conditions for chemistry but constant flow rate BCs for flow
Hi all, I'm using TOUGHREACT with ECO2N module. In the simulations, the flow is injected at a constant flow rate and due to dissolution/precipitation, the pressure would change at the boundary cell.…

Input conversion error, unit 33
Hi there, I've modified a sample input file flow.inp (in P5-ECO2N) to use our dimensions and parameter values. But after running the toughreact executable, this is the error message I've got.…
