PerGeos Software

Digital rock analysis

Thermo Scientific PerGeos Software for digital rock analysis is the industry's first software designed to help geoscientists rapidly interpret digital rock imagery so that E&P engineers can quickly and easily obtain meaningful, actionable data. Its visualization, processing, and analysis of 2D and 3D digital rock imagery enables improved evaluation of reservoir quality and faster understanding of static and dynamic rock properties that impact production.

PerGeos Software is comprised of the most advanced set of artifact removal, filtering, and analytical algorithms on the market. It can be used as a standalone software platform or bundled with a variety of applications to customize the user experience with additional functionality for digital core analysis.

Collaboration - Building a Common Rock Model

Oil companies currently analyze a wide array of image data types and formats when trying to understand the physical characteristics of reservoir rock. By learning how those characteristics relate to the potential value of a reservoir, geoscientists can then relate those observations to the production techniques required to optimize that value. Information extracted from these disparate sources can now be managed digitally with PerGeos Software via a collaborative workspace.

PerGeos Software offers a flexible, multi-disciplinary, modular architecture that supports the exchange of information and rock statistics between geologists, petrophysicists, and core analysts. Such collaboration facilitates the creation and sharing of a common rock model much faster than with traditional core analysis methods.

In addition to the standard, built-in, automated image processing workflows, PerGeos Software offers a suite of applications that provide a customizable user experience. Users can select from the following add-ons:

  • Pore Network Flow: Simulate two-phase flow in your rock and obtain curves of capillary pressure, relative permeability and resistivity index. With PerGeos Software Pore Network Flow feature, you can easily obtain two-phase properties from your porous rock.
  • Core Profile: A powerful, whole-core data application that enables co-visualization of whole-core CT, core photography, and petrophysical logs in a single workspace. Core Profile also creates virtual logs based on whole-core CT data for further calibration and communication of how changes in rocktype impact how petrophysical properties are measured down-hole.
  • Petrophysics: A suite of models for rock property analysis and simulations to derive measurements such as absolute permeability, Archie m (from formation factor F), thermal properties, and MICP saturation curve simulation.
  • Pore Statistics: An application that contains a straightforward operation to extract a pore network model from a segmented 3D dataset (FIB-SEM or microCT). The application includes automated workflows to quantify 2-phase and 3-phase fluid storage.

Consistency – Implementing Data Processing & Modeling Best Practices

PerGeos Software helps geoscientists rapidly interpret digital rock imagery to better understand formation features and measure physical properties on reservoir rock. A simplified user interface is combined with automated workflows, allowing users to quickly create and curate best practices to ensure high-quality data regardless of the image modality (CT, SEM, optical microscopy, etc.) and independent of the user’s intimacy with the software.

Confidence – Generating Reliable Data, Faster

Multi-scale, microscopic imagery and advanced digital rock modeling provide the only direct measurement for analyzing critical structural characteristics and physical properties, such as grain size, pore space and connectivity, clay distribution, and porosities associated with mineralogy or organic matter. The integrated philosophy of PerGeos Software enables users to investigate and combine multi-modal datasets to qualitatively and quantitatively validate results, giving greater confidence in the reliability of the observations and derived properties. PerGeos Software features tools to side-by-side compare and/or fuse datasets; for example, optical thin sections and mineralogy can be overlaid with ease. It also provides new functionality for core analysts who want to understand observations from core- to pore-scale.

The speed and accuracy with which PerGeos Software delivers digital rock results is important for reservoir engineers awaiting these critical inputs for their geomodels. Knowledge of these properties helps asset managers visualize and understand the ultimate potential recovery of a reservoir, thereby improving their estimates of reserves and overall production-related CapEx investments.

Customized – Engineered for Oil & Gas

PerGeos Software provides the flexibility to customize workflows via an intuitive user interface designed specifically for oil and gas reservoir characterization and digital rock analysis. PerGeos Software incorporates new artifact removal and analytical tools, including microCT beam-hardening filters and MICP simulation workflows that provide any user the valuable tools needed to answer the most challenging image and analytical questions. Even for non-experts, customized workflows are possible through Thermo Fisher Scientific’s in-house experts, who can create custom scripts to fit any requirement.
