Geothermal production well temperature declines too slow

Please login with a confirmed email address before reporting spam

Hey all,

I'm new to comsol (i've been using it for 3 weeks now). I'm currently modelling something that looks like the 'geothermal doublet' application from comsol, but instead I have a pressure driven flow. It also does not contain a fracture.

My problem now is that I want to compute the production temperatue of my production wells over the years. It seems like the well influences the temperature as such it remains high around the production well. Even after 80 years the temperature only decreased with 10 degrees, while the surrounding dropped to the injection temperature!

The image attached is a cross section through the mirrored simplified model with two wells inside an aquifer in between two impermeable layers.

Anyone please help?
