Semianalytical solution for CO2 leakage through an abandoned well.
Capture and subsequent injection of carbon dioxide into deep geological formations is being considered as a means to reduce anthropogenic emissions of CO2 to the atmosphere. If such a strategy is to be successful, the injected CO2 must remain within the injection formation for long periods of time, at least several hundred years. Because mature continental sedimentary basins have a century-long...
متن کاملAccelerating CO2 Dissolution in Saline Aquifers for Geological Storage — Mechanistic and Sensitivity Studies
One of the important challenges in geological storage of CO2 is predicting, monitoring, and managing the risk of leakage from natural and artificial pathways such as fractures, faults, and abandoned wells. The risk of leakage arises from the buoyancy of free-phase mobile CO2 (gas or supercritical fluid). When CO2 dissolves into formation brine, or is trapped as residual phase, buoyancy forces a...
متن کاملCO2 Storage in Geological Media: Role, Means, Status and Barriers to Deployment
Carbon dioxide capture and geological storage is an enabling technology that will allow the continued use well into this century of fossil fuels, mainly coal, for power generation and combustion in industrial processes because they are relatively abundant, cheap, available and globally distributed, thus enhancing the security and stability of energy systems. Geological media suitable for CO2 st...
متن کاملNumerical Models for Evaluating CO2 Storage in Deep, Saline Aquifers: Leaky Wells and Large-Scale Geological Features
Geological storage of CO2 is one of the most promising strategies for obtaining largescale reduction in global CO2 emissions. Deep, saline aquifers within sedimentary basins have been identified as attractive options for geologic storage with a large potential storage capacity for CO2 disposal. An important risk of geological storage is the potential for leakage along existing oil and gas wells...
متن کاملAn integrative approach to robust design and probabilistic risk assessment for CO2 storage in geological formations
CO2 storage in geological formations is currently being discussed intensively as a technology with a high potential for mitigating CO2 emissions. However, any large-scale application requires a thorough analysis of the potential risks. Current numerical simulation models are too expensive for probabilistic risk analysis or stochastic approaches based on a brute-force approach of repeated simula...
