Quantification of fluids injection in a glass-bead matrix using X-ray microtomography.

Several daily activities involve the accumulation or percolation of fluids through porous media. X-ray microtomography is a non-invasive technique capable of providing images of the internal microstructure of materials showing the different phases of fluid distribution present in the sample directly or at the pore-scale. This methodology was used to qualitatively and quantitatively assess samples consisting with glass beads of standard size, which contained fluid filling a porous region.

Effects of manual threshold setting on image analysis results of a sandstone sample structural characterization by X-ray microtomography.

Binarization process plays an important role in structural characterization by means of micro-CT images analysis. The choice of the correct threshold to separate porous phase from the material is the procedure for binary images creation. Slight variations of the threshold level led to substantial variations in physical parameters determination.
