Material properties from two-dimensional image

A system for analyzing a rock sample, comprising:

• a first imaging device configured to produce a digital image volume representative of the rock sample;
• and
• a computing device coupled to the imaging device and comprising:
• a processor;
• and
• a memory coupled to the processor, and configured to store instructions that, when executed by the processor, configure the computing device to:
• segment the digital image volume, to associate voxels in the digital image volume with a plurality of rock fabrics of the rock sample;
• perform image processing on the digital image volume to determine a material property of each of the rock fabrics;
• select, from a set of nomograms, a nomogram having an associated grid size, wherein the selected nomogram associates the material property of each of the rock fabrics with a fractional bounceback parameter (FBP) value between a lower FBP threshold and an upper FBP threshold;
• and
• associate each voxel in the digital image volume with an FBP value based on the selected nomogram.

A non-transitory, computer-readable medium encoded with instructions that, when executed by a processor, cause the processor to:

• segment a digital image volume corresponding to an image of a rock sample, to associate voxels in the digital image volume with a plurality of rock fabrics of the rock sample;
• perform image processing on the digital image volume to determine a material property of each of the rock fabrics;
• select, from a set of nomograms, a nomogram having an associated grid size, wherein the selected nomogram associates the material property of each of the rock fabrics with a fractional bounceback parameter (FBP) value between a lower FBP threshold and an upper FBP threshold;
• and
• associate each voxel in the digital image volume with an FBP value based on the selected nomogram.
