How can i investigate the interaction between gas-rock or gas water rock in phreeqc?

26 November 2020 1 9K Report

I want to investigate the reaction between a mineral (Calcite) and a gas phase (H2) which has been stored at a depleted gas reservoir.

I try to model this by defining a solution and put H2(g) as equilibrium phase and defining a Reaction by Calcite, but it doesn't give me a reasonable result.

I really appreciate if some one can help me with this

Dear Dr. Sara,

You can use this exemple to follow interaction mineral and gaz, if you have a Ca CO3 you can use CO2 activity.

Kind regards
