Digital Rock Analysis for Geology

Digital Rock Analysis ( DRA ) is the study of rock samples by use of rock imagery data with the goal of understanding rock properties.

Digital Rock Analysis encompasses a multi-disciplinary approach involving advanced microscopy and physics combined with geology, geochemistry, petrophysics, and petroleum engineering to understand the pore-scale microstructure of reservoir rock. It is used to help E&P operators reduce exploration and production risk while informing decision-making to improve recovery.

Thermo Scientific PerGeos Software is a comprehensive Digital Rock Analysis solution that provides geologists with advanced analytical tools to better evaluate the reservoir quality.

Rock core plug analysis using X-ray computed tomography

Using whole-core X-ray CT and micro-CT plug data: Understand lamination. Analyze core and heterogeneity logs. Measure fracture density and orientation. Characterize the pore space.

Segment pores, clays, and grains. Run accurate grain size and shape analysis. Perform advanced porosity calculation and pore size distribution analysis.

Digital rock analysis with focused ion beam milling

Focused Ion Beam coupled with Scanning Electron Microscopy systems (FIB-SEMs) are invaluable tools that produce high-resolution imagery of nanoporous structures of tight reservoirs and for multi-scale analysis.

Using FIB/-SEM image data: Quantify pores, clays, organic matter, grains. Perform 3D pore-space characterization. Analyze organic versus mineral porosity. Run 3D size and shape analysis on grains.

Scanning electron microscopy for geological thin section analysis

Scanning Electron Microscopy (SEM) systems allow geologists to capture high-quality images of thin sections of rocks.

Using SEM thin sections: Perform petrography workflows. Run grains size and shape analysis, pore-space characterization. Get high-resolution mineralogy information.

From Core to Pore, using imagery from large CT to FIB/SEM systems, PerGeos Software helps you digitally understand and validate observations and properties of your rock data with a high level of confidence.

Ability to interpret images at multiple resolutions from multiple modalities, advanced 2D/3D and 3D/3D registration tools and adaptive thresholding make PerGeos Software 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.
