problems with non-isothermal three phase flow in the porous media

Please login with a confirmed email address before reporting spam

I have built a non-isothermal three phase flow in the formation: low temperature CO2 injection into the formation to displace oil. Set the phase saturation, pressure and temperature as the primary variable.

I have encountered this problem with my model: everything is ok, but the pressure drop sharply after short time of flooding.
The saturation model and pressure model I use are from the paper NIU BEN wrote Coupling Miscible Flow and Geochemistry for Carbon Dioxide Flooding into North Sea Chalk Reservoir and add a energy model.

Now I have built 2D and 3D models.

Can anybody give me some instructions???
Tks
