Approach•Calculate average apparent rock-fabric number from core data for each stratigraphic layer.
•Calculate permeability profile for each well using apparent rock-fabric number from stratigraphy and total porosity from logs as input into global permeability transform.
•Interpolate permeability between wells constrained by seismic stratigraphy.
Problem•Only porosity and gamma-ray logs available.•Highly variable rock fabrics typical of icehouse conditions.
