Fault reactivation during CO₂ sequestration: Effects of well orientation on seismicity and leakage

Injection or withdrawal of fluid at depth may trigger felt seismicity. Such human‐induced seismicity is a key environmental concern related to the exploitation of natural underground resources. Thus, understanding how to avoid triggering felt earthquakes plays a crucial role in the success of underground anthropogenic activities, such as CO 2 geological storage. In this work, we conduct 3D simulations of injection‐triggered fault reactivation,...
