Geological and petrophysical properties of rocks

From core to pore, using imagery from large CT to FIB-SEM systems, Thermo Scientific Avizo Software for Digital Rock Analysis (DRA) helps you digitally understand and validate observations and properties of your rock data with a high level of confidence.


Whole core CT data

Import and pre-process CT imaging data. Assemble multiple large core scans, generate logs, perform dip and strike analyses, conduct rock typing and facies classification, generate automated reports. Understand lamination. Analyze core and heterogeneity logs. Measure fracture density and orientation. Evaluate and select sub-regions of interest for down-scale investigations.

 

Avizo Software DRA allows petrophysicists to generate pseudo-logs, to co-visualize core CT images, wireline logs, and unwrapped core images. Use dual-energy CT (DECT) technique to characterize core density and atomic number or to perform core classification based on reference materials.


Core CT plugs

Obtain actionable insights on your core plug imagery data acquired using X-ray computed tomography.

 

Perform rock typing, porosity estimation, or saturations analysis. Extract and analyze wormholes. Use dual energy CT (DECT) technique to obtain actual density information that can be compared with density logs and used for further characterization of rock formations. Identify and select sub-plugs for further down-scale analysis.


Micro-CT core plugs

Microfocus X-ray tomography (micro-CT) allows you to capture high-resolution imaging on core samples at the millimeter scale.

 

From this imaging data, Avizo Software DRA allows geologists, petrophysicists, and reservoir engineers to obtain advanced information on the rock micro-structure. Segment pores, clays, and grains. Run accurate grain size and shape analysis. Perform pore space and pore network analysis. Run fluid flow properties calculation, such as pore size distribution or grain classification.

 

Calculate absolute permeability and two-phase flow properties. Run fluid flow simulations. Calculate formation factor, electrical resistivity. Simulate mercury injection capillary pressure.


Rock thin section images

Scanning electron microscopy (SEM) systems allow geologists to capture high-quality images of thin sections of rocks and perform petrography workflows.

 

Avizo Software DRA offers a dedicated digital platform to extract petrology or mineralogy information from this thin section imagery data. It allows for the characterization of pore space, to capture properties such as pore size distribution, intergranular porosity, or grain size, shape and orientation. It also provides tools to perform mineralogical analysis using SEM-EDS data.

 

Avizo Software DRA also provides the unique ability to perform process-based modeling, which is the simulation of the formation of the rock by generating a 3D model from 2D images analyses.


Focused ion beam scanning electron microscopy of rocks

FIB-SEM electron microscopy systems are invaluable tools that produce high-resolution imagery of nanoporous structures of tight reservoir and for multi-scale analysis.

 

Avizo Software DRA provides a comprehensive, dedicated feature set to perform digital analyses of FIB-SEM rock sample images. It offers unique imaging artifact correction capabilities, pre-processing wizard, advanced segmentation, quantification, and simulation tools.

 

Avizo Software DRA allows geologists to accurately characterize 3D pore space and organic vs mineral matter volume fractions, to run 3D size and shape analysis on grains. It also provides tools for creating numerical pore network models to perform petrophysical analysis such as mercury injection capillary pressure simulation or fluid flow simulations for permeability calculation.


Multi-scale geological and petrophysical analysis

From core to pore, using imagery from large CT to FIB-SEM systems, Avizo Software DRA helps you digitally understand and validate observations and properties of your rock data with a high level of confidence.

 

The ability to interpret images at multiple resolutions from multiple modalities, advanced 2D/3D and 3D/3D registration tools, and adaptive thresholding make Avizo Software DRA a unique digital platform for powerful up-scaling workflows.

 

This allows geological and petrophysical properties to be numerically obtained with confidence since all scales of the pore space can be analyzed and interpreted to calculate properties such as global porosity or relative permeability.
