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.

Three-dimensional characterization of micro-fractures in shale reservoir rocks

Three-dimensional characterization of micro-fractures in shale reservoir rocks

Fractures are crucial for unconventional hydrocarbon exploitation, but it is difficult to accurately observe the 3D spatial distribution characteristics of fractures. Microtomography (micro-CT) technology makes it possible to observe the 3D structures of fractures at micro-scale. In this study, micron-CT scanning is conducted on multiple mud-shale samples of source rocks in the Permian Lucaogou Formation, Junggar Basin. The Avizo software is applied to process and segment the micron-CT images... Read more

Pore‐Scale Experimental Investigation of Two‐Phase Flow Through Fractured Porous Media

Pore‐Scale Experimental Investigation of Two‐Phase Flow Through Fractured Porous Media

Understanding transport mechanisms that govern two-phase flow in fractured porous media has direct implications for natural and industrial processes such as extraction of hydrocarbons from fractured reservoirs, geologic sequestration of CO2, or fluid flow through aquifers.

We present the results of a systematic pore‐scale experimental investigation of two‐phase oil/brine flow through a miniature water‐wet, fractured sandstone core sample. X‐ray microtomography is employed to ge... Read more

Combining high-resolution with larger volume images for improved characterization of mudstone reservoirs

Combining high-resolution with larger volume images for improved characterization of mudstone reservoirs

Optimization of production from shale reservoirs requires understanding of rock properties over a range of scales.

Multiple imaging techniques can be combined to determine the nature, connectivity, and wettability of nano-scale pore systems as well as the underlying mineralogy and organic textures that control reservoir behavior and the propensity of the matrix to fail and to contain expulsion cracks. The current study demonstrates new capabilities in integrated multiscale and time-res... Read more

Laboratory Noble Gas Migration Experiments Through Rock

Laboratory Noble Gas Migration Experiments Through Rock

The Underground Nuclear Explosion Signature Experiment (UNESE) is a multi-laboratory effort to improve U.S. capabilities to detect, locate, identify, and characterize underground nuclear explosions. Here we present a lab-scale experiment developed to test advective gas transport though rock samples at in-situ conditions, and results of tests performed at ambient conditions on rocks collected from the site of a field-scale experiment. Gas transport results are compared to pore and fracture net... Read more
