Why CGG’s Global Automated Mineralogy Services?

We believe in challenging the status quo and doing things differently in order to maximize the value for our customers.


We challenge the status quo by designing products, services and quantitative workflows that answer key questions on reservoir characterization covering all lithology types that help to further reduce uncertainty at the well bore to play scale.

Established in 2006, our Automated Mineralogy services benefit from some of the best equipment and highest level of expertise in the Industry. We utilize state-of-the-art Scanning Electron Microscopy and Energy Dispersive Spectroscopy (SEM-EDS), including our proprietary RoqScan™ technology. Our experience covers all major and minor conventional and unconventional resource plays around the world.

Global Automated Mineralogy Experience


We group undertake various types of project, whether independent studies or forming part of an integrated multidisciplinary project. Automated mineralogy sample preparation and analysis is non-destructive allowing for the quantification of both compositional and textural data. Some of our extensive workflows and deliverables are presented below:

Quantitative mineralogyMineralogical analysis of core and cuttings.

Grain size and shape analysis
  • Reservoir quality and characterization
  • Quantitative mineralogical analysis of core, cuttings, SWC and thin sections
  • Quantitative pore analysis
    • Porosity
    • Pore size distribution
    • Pore aspect ratio
  • High resolution mineral mapping
  • Grain size and shape analysis
  • Rock typing
  • Quantitative lithotyping
  • Rheology (brittleness vs. ductility) and geomechanical calculations
  • Well-to-well mineral and elemental correlation (Chemostratigraphy)
  • Heavy mineral provenance evaluation
  • High resolution Backscatter Electron (BSE) and Secondary Electron (SE) imaging for diagenetic evaluation.
  • Borehole stability
  • Validation of log data
  • Input into optimized and geometric completions
  • Drilling contamination
  • Integrated petrophysical modelling and upscaling into seismic reservoir characterization models (seismic attribute volumes).

Two types of automated mineralogy services are offered:

  1. bespoke laboratory analysis for detailed rock properties evaluation, and;
  2. exclusively developed portable analytical system, RoqScan, for well site, core store and off-site analysis.

Details of these services are provided in their designated tabs.
