The understanding of the coupled thermo-hydro-mechanical behaviour of fault zones in naturally fractured reservoirs is of fundamental importance for a variety of societal and economic reasons, such as the sustainable energy transition for the safe use of natural resources. The idea here is to carry out a thermally controlled in situ fluid injection experiment in one of the faults accessible from the Tournemire underground research laboratory in Southern France. A heating system will be installed around the injection and enable a precise and controlled incremental increase the thermal load. In addition, an important monitoring system will be installed to measure the seismic and aseismic events as well as temperature evolution. A series of laboratory experiments will be conducted to understand the chemical and structural evolution occurring within fault zones during thermal and hydraulic loading.

了解天然裂缝性储层中断层带的耦合热-水-力学行为对于各种社会和经济原因具有根本重要性，例如安全使用自然资源的可持续能源转型。这里的想法是进行一个热控制的原位流体注入实验中的一个故障访问从法国南部的Tournemire地下研究实验室。加热系统将安装在注射周围，并能够精确和受控地增加热负荷。此外，还将安装一个重要的监测系统，以测量地震和地震事件以及温度演变。将进行一系列的实验室实验，以了解在热负荷和水力负荷期间断层带内发生的化学和结构演变。
