Abstract
A method and system for non-destructive characterization of porous media samples are disclosed. The method for porous media characterization by one or more central processing units (CPUs) includes obtaining one or more segmented images from a set of images of a porous media sample, determining one or more fluid-fluid interfaces (FFIs) within one or more segmented images for each pixel of the one or more segmented images, and based at least in part on the FFIs, extracting one or more characteristics of the porous media sample.
Claims19
A method for porous media characterization by one or more central processing units (CPUs), comprising:
- obtaining one or more segmented images from a set of images of a porous media sample;
- determining one or more fluid-fluid interfaces (FFIs) within one or more segmented images for each pixel of the one or more segmented images;
- and
- based at least in part on the one or more FFIs, extracting one or more characteristics of the porous media sample, comprising:
- determining one or more three-phase contact lines (TCLs) within the one or more segmented images;
- generating one or more two-dimensional (2D) slices of the one or more segmented images perpendicular to each of the one or more TCLs;
- processing the one or more 2D slices to map each pixel of the one or more 2D slices to at least one of:
- a TCL:
- an FFI;
- a fluid-solid interface (FSI);
- a solid phase;
- a wetting phase;
- or
- a non-wetting phase;
- and
- determining one or more contact angles of the porous media sample.
A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors, cause one or more central processing units (CPUs) to:
- obtain one or more segmented images from a set of images of a porous media sample;
- determine one or more fluid-fluid interfaces (FFIs) within one or more segmented images for each pixel of the one or more segmented images;
- and
- based at least in part on the one or more FFIs, extract one or more characteristics of the porous media sample, comprising:
- determining one or more three-phase contact lines (TCLs) within the one or more segmented images;
- generating one or more two-dimensional (2D) slices of the one or more segmented images perpendicular to each of the one or more TCLs;

- a TCL:
- an FFI;
- a fluid-solid interface (FSI);
- a solid phase;
- a wetting phase;
- or
- a non-wetting phase;
- and
- determining one or more contact angles of the porous media sample.
