Specify the time-dependent pressure boundary condition in TOUGH+HYDRATE
Hi, everyone Can I set a time-dependent pressure boundary condition in the TOUGH+HYDRATE? I wonder if it is possible to decrease the pressure of the production well over time. Thanks!

Gas production units in TOUGH+ is it m3/d or Sm3/d in Hydrate_Status : T+H v 1.5
I am trying to figure out whether T+H v 1.5 reports Sm3/d in Hydrate status file or simply m3/d. If it is m3/d then how do i get the necessary Thermodynamic variables to change it to Sm3/d.…
