Glossary:Geo-mechanics
Geomechanics is the study of the mechanical behavior of rocks, including their response to stresses and strains. In underground storage systems, geo-mechanical considerations include the stability of the rock formation, the potential for subsidence, faulting, or fracturing, and the potential impact of fluid injection or extraction on the rock’s mechanical properties. Geo-mechanical modeling is crucial for predicting the behavior of the system over time and ensuring its long-term safety and effectiveness. By accurately modeling the geo-mechanical response to fluid injection or extraction, we can identify potential risks and develop strategies to mitigate them. Understanding the potential for subsidence, fault reactivating, and fracturing can inform decisions about where to place injection wells and how to control injection rates.[1]
