Hello all,

I’m new to OGS and would appreciate any guidance that you might be able to give on how to tackle a problem I am working on;

I’m modelling a deep closed-loop geothermal system comprising two vertical wells connected laterally toe to toe. I’ve been reading about the HEAT\_TRANSPORT\_BHE process as it looks to be somewhat close to what I’m trying to model, however, I’m not sure whether it’s possible to adapt it for my needs.

I would like to be able to get a read-out of how much thermal energy is transferred into the heat-bearing fluid from the surrounding rock at a given depth/temperature (and/or the fluid temperature achieved at surface). Is this possible to code into a polyline? I’d like to keep the model relatively simple.

Many thanks in advance to anyone who shares any thoughts on how to approach this.

Best regards,

Joe

Dear Joe,

according to my understanding, I think there is a suitable reference related to the model: [UFZ - Publikationsverzeichnis - Helmholtz-Zentrum für Umweltforschung UFZ](https://www.ufz.de/index.php?de=20939&pub_id=24137)

Best regards,

Thank you very much Chaofan. Apologies for the slow reply.  
It looks like there’s some very useful information in that paper, thanks.
