Confining beds option geothermal doublet



Does anybody have a benchmark problem or an example for a geothermal doublet (with 1 production well and 1 injection well) in a porous aquifer using the confining beds option (MOP(15)=1)? 

It seems that I can never reproduce the Gringarten analytical solution using TOUGH2 even for a very simple geometry. The result is close but quite not the same, especially the thermal breakthrough time observed using TOUGH2 is always too early compared to the one obtained using the analytical solution.

Thanks in advance for your replies!

  • Hi Virginie, If you post your input file and a citation for the Gringarten solution you are trying to match, I will take a look and see if I can suggest any changes that might give you a better match.  In general, you have to be quite careful when creating your grid to get a good match to an analytical solution.  Christine
