Conclusion

The preceding analysis, which has been developed and used for real geothermal cases, can be used to characterize and control, within the framework of current geothermal regulations, the possible interferences between hydraulic and thermal drainage zones of the two wells of a geothermal doublet in an aquifer (at free surface or under load).

It is essential to be able to correctly anticipate possible interferences between structures, otherwise the thermal performance of thermodynamic machines, whether for heat or cold production, will rapidly deteriorate during operation.

Analytical calculations of the development over time of hydraulic and thermal plumes induced by the operation of geothermal borehole doublets operating in the aquifer are carried out under simplified operating conditions:

• aquifer...
