AbstractThis dataset contains the input files for numerical assessment of the risk of CO2 leakage from gigatonne-scale geologic carbon storage sites over geological time scales. Numerical models are one-dimensional and evaluate vertical transport of CO2 through a multilayered sedimentary basin comprising a sequence of aquifers and caprocks.
DescriptionThis dataset contains the input files for numerical assessment of the risk of CO2 leakage from gigatonne-scale geologic carbon storage sites over geological time scales. Numerical models are one-dimensional and evaluate vertical transport of CO2 through a multilayered sedimentary basin comprising a sequence of aquifers and caprocks. The caprocks are assumed to be of either high or low sealing capacity, corresponding respectively to best-case and worst-case scenarios for CO2 migration. Accordingly, the dataset has two folders, each containing data for a leakage assessment scenario: - “Best_case_scenario.gid” in which the considered caprocks have low intrinsic permeability k=1·10-20 m2, high capillary entry pressure p0=2.5 MPa, and high powerlaw exponent n=6 for relative permeabilities - and - “Worst_case_scenario.gid” in which the caprocks have high permeability k=1·10-16 m2, low capillary entry pressure p0=0.1 MPa and low powerlaw exponent n=3 for relative permeabilities. In each folder, there is a file with the name of the folder ended as “_gen.dat” which contains the input data of the model, including material properties, initial and boundary conditions and the time intervals. There is also a file ended as “_gri.dat” that includes the information on the mesh. The file “root.dat” includes the name of the model. To run the simulation, execute the Code_Bright executable “Cb_v9_3.exe” in a folder that contains the three input files and the executable.
