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

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

Computational elastic upscaling of sandstone on the basis of X‐ray micro‐tomographic images

Computational elastic upscaling of sandstone on the basis of X‐ray micro‐tomographic images

Up‐scaling the elastic properties of digitized rock volumes as obtained from X‐ray computer tomography (CT) imaging via computer simulations has the potential to assist and complement laboratory measurements.

This computational up‐scaling approach remains a challenging task as the overall elastic properties are not only dependent on the elastic properties of individual grains but also on the hardly resolvable pore spaces between adjacent grains such as micro‐cracks. We develop ... Read more

In Situ Chemically-Selective Monitoring of Multiphase Displacement Processes in a Carbonate Rock Using 3D Magnetic Resonance Imaging

In Situ Chemically-Selective Monitoring of Multiphase Displacement Processes in a Carbonate Rock Using 3D Magnetic Resonance Imaging

Accurate monitoring of multiphase displacement processes is essential for the development, validation and benchmarking of numerical models used for reservoir simulation and for asset characterization.

Here we demonstrate the first application of a chemically-selective 3D magnetic resonance imaging (MRI) technique which provides high-temporal resolution, quantitative, spatially resolved information of oil and water saturations during a dynamic imbibition core flood experiment in an Esta...

Validation of model predictions of pore-scale fluid distributions during two-phase flow

Validation of model predictions of pore-scale fluid distributions during two-phase flow

Pore-scale two-phase flow modeling is an important technology to study a rock’s relative permeability behavior. To investigate if these models are predictive, the calculated pore-scale fluid distributions which determine the relative permeability need to be validated. In this work, we introduce a methodology to quantitatively compare models to experimental fluid distributions in flow experiments visualized with microcomputed tomography.

First, we analyzed five repeated drainage-i... Read more

Heterogeneity Logs  in PerGeos 1.5

Heterogeneity Logs in PerGeos 1.5

The Core Profile workspace of PerGeos already provides the right tools to visualize logs, CT cores, Bore Hole images and Photographs.

A unique preprocessing step allows the cores barrel to be intelligently removed, the core to be re-oriented if it is not perfectly vertical, and all the cores to be stitched together regardless of the total size.

This allows a user to browse in real time an entire 3D digital well of 100+ cores and apply post-processing operations such as logs gene... Read more
