How to switch between injection well to production well (time dependent)
Hi, Everyone,
I am a PhD student. I need some urgent help in the TOUGH2. I wan to switch the well properties between the injection well and the production well during the simulation. I know there is a table to control the well properties. I have no idea how to realize this function. Can anyone help me ? Thanks. This is really important to me. I really appreciate your time in reading this post.

Yes, use the time dependent generation/injection rate in GENER to switch from injection to production. Use two sink/sources in the same element, one for the (positive) injection at certain times (using COMx to identify which component x you want to inject). When the injection goes to zero, make the second sink/source active by specifying a (negative) MASS flow rate. Just make sure the tables with LTAB entries you specify has zero rates for one sink/source while the other is non-zero.
Hope this helps

Hi Stefan,
Thanks for quick reply!
I am using Tough3 and tried sample problem of Five-spot (rfp-EOS1) with same as well as different sink/source name. And I found that there is no difference in the result. However, when tried with same sink/source name and GOFT is specified then it shows the result (in GOFT***.CSV file) of first entry in the GENER, which is quite convincing to me.I also found that, when I change the order of the sink/source in GENER there is a very slight/negligible change in the output, I am not sure if this is supposed to be happened.
All results and INPUT files are attached here in case if anyone is interested.
Thanks,
Amol
