Welcome to the PerGeos Use Case Gallery

Below you will find a collection of use cases using PerGeos Software. Based on the technology of its predecessor Avizo Software, PerGeos is a robust software platform for visualizing, processing, and analyzing 2D and 3D digital rock image data.

These use cases include scientific publications, articles, papers, posters, presentations or even videos that show how PerGeos is used to address various scientific and industrial research topics.

Major advance in well bore analysis with CT inspection

Major advance in well bore analysis with CT inspection

Premier, COREX has been providing core analytical services to the oil and gas industry for more than 30 years. Within the last decade it has augmented its rock core investigations by sending samples for analysis approximately every week to Nikon Metrology’s centre of excellence for micro-focus computed tomography (micro-CT) in Tring, Hertfordshire.

Drilling for oil or gas is an expensive business, whether offshore or on land, so it is essential for E&P (exploration and producti... Read more

Dynamic strength and failure modes of sandstone under biaxial compression

Dynamic strength and failure modes of sandstone under biaxial compression

Geomaterials are increasingly being subjected to the quasi-static confinements and dynamic loadings, and thus it is critical to characterise dynamic behaviour under the coupled static-dynamic loading conditions. In this study, a series of dynamic biaxial compression tests was performed on cubic specimens of sandstone by using a triaxial Hopkinson bar system, high-speed three-dimensional digital image correlation (3D-DIC) and synchrotron-based micro-computed-tomography (μCT).

Experimental Investigation of 3D Printed Rock Samples Replicas

Experimental Investigation of 3D Printed Rock Samples Replicas

Laboratory Experiments on rock specimens are designed for understanding and characterizing subsurface environment, quantifying potential recovery, and tuning fluid flow models in porous media. The spatial variability and reservoirs’ heterogeneities predicate acquiring expensive cores from different locations. These experiments are mechanically and petrophysically destructive and cannot be repeated or extended on the same core. Replicating core samples with 3D-printing technology innovation ... Read more

Uncertainty span for relative permeability and capillary pressure by varying wettability and spatial flow directions utilizing pore scale modelling

Uncertainty span for relative permeability and capillary pressure by varying wettability and spatial flow directions utilizing pore scale modelling

Relative permeability and capillary pressure are key properties within special core analysis and provide crucial information for full field simulation models. These properties are traditionally obtained by multi-phase flow experiments, however pore scale modelling has during the last decade shown to add significant information as well as being less time-consuming to obtain. Pore scale modelling has been performed by using the lattice-Boltzmann method directly on the digital rock models obtain... Read more

X-ray computed tomography of planetary materials: A primer and review of recent studies

X-ray computed tomography of planetary materials: A primer and review of recent studies

X-ray computed tomography (XCT) is a powerful 3D imaging technique that has been used to investigate meteorites, mission-returned samples, and other planetary materials of all scales from dust particles to large rocks.

With this technique, a 3D volume representing the X-ray attenuation (which is sensitive to composition and density) of the materials within an object is produced, allowing various components and textures to be observed and quantified. As with any analytical technique, a ... Read more

Handling Large data in PerGeos

Handling Large data in PerGeos

We introduce here some techniques to visualize and process large data, mostly targeting the high resolution data acquired by Heliscan microCT.

The data is considered as “large” in the sense that its size exceeds the size of the GPU memory and/or the size of the RAM of the machine.

The following workflow:

  • Segmentation
  • Porosity / Connected porosity determination
  • Pore separation / Pore Size distribution
  • Grain size distribution
... Read more

Improving Whole Core Characterization with Automated Log Generation in PerGeos

Improving Whole Core Characterization with Automated Log Generation in PerGeos

The Core Profile Extension, available for PerGeos, provides a powerful toolset for visualization and analysis of whole core CT data. Within this extension the user can load and visualize an entire wells worth of CT data as well as performing detailed analysis of geological and chemical features by utilizing the powerful image analysis library fundamental to PerGeos.

In this example, we illustrate the usefulness of core profile in augmenting traditional core analysis routines and provid... Read more
