PerGeos Software Extensions

Go further in your Digital Rock Analysis

Thermo Scientific™ PerGeos™ Software is a configurable solution. In addition to the built-in, automated image processing workflows, PerGeos Software offers a suite of extensions designed to help users make statistical observations about the sample as it relates to their specific function and then allows them to transfer the knowledge in a digital environment for interactive QC for the entire asset team.

Pore Network Flow

The Pore Network Flow Extension offers a platform for simulating two-phase flow processes in porous rocks. The pore-space is modeled by a pore network model that is built based on a 3D image of the rock sample. The primary drainage, water flooding and secondary drainage processes can be simulated using the two-phase flow simulation tool. The wettability of the rock-fluid system is modeled by assigning contact angle distributions for each two-phase flow process. The saturation-dependent properties of relative permeability, capillary pressure and resistivity index are calculated for each simulated process.

Core Profile

The Core Profile extension facilitates correlated viewing of depth-matched with whole-core CT data, whole-core photos, and petrophysical logs in a single software environment. This module includes an automated core assembler that automatically aligns, stacks, and stitches whole-core data into a single image. The user can then segment and extract a virtual log from this dataset to compare to conventional petrophysical logs.


The Petrophysics extension provides access to image-based models that permit the simulation of flow and electrical and thermal properties of the sample, including absolute permeability, electrical resistivity, formation factor, capillary pressure, and more. With this information, geologists can link specific depositional environments and structures to associated physical behavior—a key aspect of reservoir quality.

Pore Statistics

The Pore Statistics extension extracts a pore network model from a segmented 3D dataset, including pore and pore throat sizes—important elements for flow modeling. Knowledge of these sizes is essential for providing guidance on and predicting the performance of production approaches for a reservoir rock type. The module also includes tools to quantify 2-phase and 3-phase fluids seen in micro-CT imaging. The ability to link rock characteristics to physical processes provides engineers with a physical basis to design completions and EOR/IOR components in a field’s development evolution.
