Chang et al., 20082008 - K. W. Chang, S. Minkoff and S. BryantModeling leakage through faults of CO2 stored in an aquifersee more developed a quasi-1D single phase flow model to examine the CO2Carbon dioxide upward migrationThe movement of fluids in reservoir rocks along a fault(geology) A surface at which strata are no longer continuous, but are found displaced, CO2Carbon dioxide lateral movement from the fault(geology) A surface at which strata are no longer continuous, but are found displaced into permeable layers and a continued but attenuated CO2Carbon dioxide flux along the fault(geology) A surface at which strata are no longer continuous, but are found displaced above the layers. The presented 1D model is compared with full-physics simulations in 2D. They concluded that although more CO2Carbon dioxide escapes from a deeper storage(CO2) A process for retaining captured CO2, so that it does not reach the atmosphere formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it through a fault(geology) A surface at which strata are no longer continuous, but are found displaced, less CO2Carbon dioxide reaches top of the fault(geology) A surface at which strata are no longer continuous, but are found displaced. Thus, attenuation can reduce riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event associated with CO2Carbon dioxide reaching the top of the fault(geology) A surface at which strata are no longer continuous, but are found displaced.
