WebCarbon dioxide is retained in geologic formations in three ways (Hitchon, 1996). First, CO2 can be trapped as a gas or supercritical fluid under a low-permeability caprock. This … WebIn this study, a numerical model is developed and applied to analyze the role of discrete fractures on the flow and transport mechanism of CO2 plumes in simple and complex fracture geometries. A unified framework is developed to model the essential hydrogeological trapping mechanisms.
Web(4) Residual gas trapping mechanism As the CO2 migrating in the reservoir, the formation water co mes back into the CO2 saturated zone. At the pore scale, CO2 is continuous in porous rocks. However, with a decrease in CO2 saturation, the continuous CO2 is disconnected at these points. WebJan 1, 2000 · Hydrodynamic trapping refers to a time-dependent hydrogeological process where injected CO2 is effectively trapped by the existence of very long travel times to the …
