Claim 11:
12. A backpropagation-enabled method for estimating the permeability of rock from a three-dimensional image of rock, comprising the steps of:
obtaining a three-dimensional image of rock, the three-dimensional image having a resolution;
applying a backpropagation-enabled trained model to segment the three-dimensional image of rock;
estimating an image permeability of the rock from the segmented image;
deriving a non-wetting liquid capillary pressure curve from the segmented image;
determining one of more permeability correction factors from the non-wetting liquid capillary pressure curve and the resolution; and
applying the one or more permeability correction factors to the image permeability of the rock to obtain a corrected permeability of the rock.
