To harness the immense potential of geothermal energy for non-intermittent baseload power, low-permeability crystalline hot rocks need to be hydraulically stimulated create Enhanced Geothermal Systems (EGS) that enable economically profitable fluid flow rates. However, hydraulic stimulation is usually associated with seismic activity has led project cancellation in a few occasions. improve our understanding coupled hydro-mechanical (HM) processes behind during both injection and...
Porosity and permeability alteration due to the thermo-poro-elastic stress field disturbance from cold fluid injection is a deciding factor for longer, more economic, safer heat extraction an enhanced geothermal system (EGS). In Soultz-sous-Forêts system, faulted zones are main flow paths, resulting porosity–permeability development over time reorientation sensitive in comparison with regions without zones. Available operational data combined through validated numerical simulation model...
The United Downs Deep Geothermal Project (UDDGP) is designed to utilize a presumably permeable steep dipping fault damage zone (constituting the hydrothermal reservoir in very low permeability granitic host rock) for fluid circulation and heat extraction between an injection well at 2.2 km depth (UD−2) production 5 (UD−1). Soft hydraulic stimulation was performed increase of reservoir. Numerical simulations are analyze results evaluate Experimental field data used characterize initial static...
<p>Geo-energies, such as geothermal energy, geologic carbon storage, and subsurface energy will play a relevant role in reaching neutrality allowing net-carbon removal towards the midcentury. Geo-energies imply fluid injection into and/or production from subsurface, which alter initial effective stress state may destabilize fractures faults, thereby inducing seismicity. Understanding processes that control induced seismicity is paramount to develop reliable forecasting tools...
<p>Enabling a widespread exploitation of Enhanced Geothermal Systems (EGS) around the world by tapping into the heat trapped radioactive granites demands better understanding fluid-induced seismicity associated with their stimulation. Induced seismicity occurs not only during hydraulic stimulation, but also after shut-in. The induced earthquakes Mw > 3 at Basel and = 5.5 Pohang are two well-known examples...
