3D confocal imaging methodology optimized for pore space characterization of carbonates

چکیده

Pore space characterization of carbonate materials is fundamental importance to a wide range earth science and engineering applications. In this study, we show how confocal microscopy can be used as reliable tool visualize quantify the heterogeneous pore in materials. imagery, quality images controlled by various factors including choice fluorophore, objective lens, medium imaging. Our experiments demonstrated that there no “fit-for-all” dye. The red dye provides more depth investigation, while blue capture large pores efficiently. investigation indicated quantitative description from significantly influenced imaging artifacts associated with complex carbonates. By applying image deconvolution, mitigated (e.g., spherical aberration, resolution deviation), extracted 3D pore-network model sample. We employed our optimized protocol macro- micropores, importantly their interconnectivity within an Indiana limestone (IL) computed pore-throat size distribution (PSD) was able inherent bimodal IL.

3D imaging and characterization of the pore space of carbonate core; implications to single and two phase flow properties

The ability of a rock to store and flow fluids is dependent upon the pore volume, pore geometry and its connectivity. Carbonate rocks are inherently heterogeneous having been laid down in a range of depositional environments and having undergone significant diagenesis. They are particularly difficult to characterise as the pore sizes can vary over orders of magnitudes and connectivity of pores ...

Generalized confocal imaging systems for free-space optical interconnections.

A generalized confocal imaging system, which is composed of two confocal lenses and one field lens, is proposed for free-space optical interconnections. Unlike in a conventional 4-f system, both the object distance and the image distance can be almost arbitrarily chosen. This advantage is especially important for practical setups in which the object distance and the image distance cannot be des...

Pore space reconstruction of vuggy carbonates using microtomography and multiple-point statistics

[1] To reconstruct complex porous media, such as carbonates, we propose a two-step approach to combine different types of images: microtomography at the resolution of a few microns to resolve large pores and vugs, with statistically reconstructed highresolution images for smaller features. Two-dimensional (2-D) thin sections provide multiple-point statistics which describe the statistical relat...
