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.
The complexity of unconventional rock systems is expressed both in the compositional variance of the microstructure and the extensive heterogeneity of the pore space. Visualizing and quantifying the microstructure of oil shale before and after pyrolysis permits a more accurate determination of petrophysical properties which are important in modeling hydrocarbon production potential. We characterize the microstructural heterogeneity of oil shale using X-ray micro-tomography (µCT), automated u... Read more

Pore-scale evolution of trapped CO2 at early stages following imbibition using micro-CT imaging
Despite its major influence on storage capacity, CO2 plume migration rate, and rates of CO2 dissolution and mineralization, there are outstanding questions regarding the mechanisms, times scales, influence of geological heterogeneity, and degree of residual trapping. The aim of the present study is to track temporal evolution of residually-trapped scCO2 ganglia during the early stages following imbibition, extract critical parameters such as fluid phase connectivity and scCO2 cluster size an...

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

Pore-Scale observations of the effect of surface treated nanoparticles on drainage processes
In this study we observe, using pore scale X-ray micro-CT imaging and advanced petrophysical analysis, how surface treated silica nanoparticles improve sweep efficiency of n-octane in drainage corefloods. Specifically, upon injection of n-octane into a brine saturated core, preferential flow paths are observed and attributed to both viscous instability and rock heterogeneity; when the displaced phase contains a modest volume of nanoparticles, the same preferential flow paths are suppressed re...
