摘要：

For investigation of the risks associated with future geological storage of CO2, and for determining the minimum requirements for the quality of geological storage sites, detailed study of possible leakage mechanisms is necessary. Mechanisms for potential leakage from primary CO2 storage in deep saline aquifers have been studied. A buoyancy-driven flow of CO2 through a percolating network of permeable bodies in an otherwise sealing cap-rock has been simulated on a geological model of the overburden composed of geological features characteristic for a marine sediments. Channels and lobes from turbidite flows are significant constituents to form a possible leakage pathway in this study. (C) 2008 Elsevier Ltd. All rights reserved
