Reservoir geomechanics is the study of the mechanical behavior of geological formations under the influence of fluid extraction and injection processes, crucial for optimizing hydrocarbon recovery and ensuring the structural integrity of reservoirs. It integrates principles from geophysics, rock mechanics, and petroleum engineering to predict and manage subsurface stresses and deformations, minimizing risks such as subsidence, wellbore instability, and induced seismicity.

Subsurface stresses

Subsurface deformations

Subsidence is the gradual sinking or settling of the Earth's surface, often due to natural processes like the compaction of soil or human activities such as groundwater extraction. It can lead to significant infrastructure damage, increased flood risk, and environmental impacts, necessitating careful monitoring and management strategies.

Subsidence

Wellbore instability

Induced seismicity refers to earthquakes and tremors caused by human activities that alter the stress and pressure conditions in the Earth's crust, such as mining, reservoir-induced seismicity, geothermal energy extraction, and hydraulic fracturing. Understanding and mitigating induced seismicity is crucial for minimizing risks to infrastructure and communities in areas where such activities are prevalent.
