Statistical approaches to leak detection for geological sequestration
Geological sequestration has been proposed as a way to remove CO₂ from the atmosphere by injecting it into deep saline aquifers. Detecting leaks to the atmosphere will be important for ensuring safety and effectiveness of storage. However, a standard set of tools for monitoring does not yet exist. …

Modeling & Optimization of CO2-Mixture Frost Growth as a Carbon Capture Process & Integration with Sequestration
… cryogenic carbon capture with subsurface geological sequestration. The first part of the study advances understanding of CO2 frost growth and densification during cryogenic desublimation. A machine-learning framework, trained on an extensive literature-based data set, predicts initial …

Reactivity of Iron-Bearing Minerals Under Carbon Sequestration Conditions
… world's ecosystem. A promising strategy is the geological sequestration of carbon dioxide, in which carbon dioxide emitted from large point sources is injected underground for storage. Under storage, carbon dioxide trapped as a carbonate mineral may be stable for geological time periods. …

Monitoring microseismic activity in core samples encased in core flooding apparatus subjected to confining and pore pressures
Geological sequestration of CO2 is considered as one of the most promising technologies to mitigate global warming. The process of CO2 injection and storage in the porous sandstones, however, may be accompanied with an increase in microseismic activity. In order to better understand the causes of …

Geomechanical Stability Analysis for Co2 Sequestration in Carbonate Formation
… pillars to build up the confidence of geological sequestration of CO2. Large scale CO2 sequestration in deep carbonate formation is a complicated geological process, which will non-reversibly transform the presumed equivalent and stable status of a sedimentary basin that formed over …

Geophysical Numerical Modeling Approach for Characterizing and Monitoring Potential Carbon Sequestration Injection Sites
Geological sequestration has been proposed as a viable option for mitigating the vast amount of CO2 being released into the atmosphere daily. Test sites for CO2 injection have been appearing across the world to ascertain the feasibility of capturing and sequestering carbon dioxide. A major concern …

Geo-chemo-mechanical modeling of sedimentary rocks: application to unconventional reservoirs and geological CO2 sequestration
… of oil and gas from organic-rich shales, geological sequestration of CO2 in sandstone host rocks and storage of nuclear waste in impermeable rocks are among the most challenging problems worldwide. Technical challenges and environmental concerns slow the growth of organic-rich shale …

Capillary Pressure Effects in the Geological Storage of Carbon Dioxide
… pertaining to surface tension effects in the geological sequestration of carbon dioxide. The aim of the thesis is to further our understanding of the role of surface tension, or capillarity, in geological flows. We consider a number of important problems related to carbon storage and present …

Improving capabilities of pore-scale modeling of multiphase flow for geological storage of CO2
… modeling of two-phase flow with applications to sequestration of carbon dioxide (CO2) in deep saline geological formations. These formations are widely available and have relatively high storage capacity to host injected CO2 for long-term as a practical solution to reduce CO2 emissions from power …

Study of reactive flow, ground deformation and real-time tomography with applications on CO₂ sequestration
Geological sequestration of CO₂ is an option to either mitigate or defer global warming and avoid dangerous climate change. Carbon dioxide is also injected into reservoirs to increase resource extraction. Currently, the rate of CO₂ injection in pilot sequestration plants or the enhanced oil …
