Rapid and Cost Efficient EOR Screening using a
Rock-on-a-Chip Approach


A valuable complement to core floods…

Core flood experiments are the industry standard to assess EOR performance. However, often only a limited amount of reservoir rock material is available to run a sufficient number of experiments and it remains, to some extent, a black box restricting a detailed description of static and dynamic flow properties.

Micromodels that resemble porous media are both complementary and an alternative to core flooding experiments. When compared to core, an unlimited amount of Micromodel chips with the same porenetwork can be produced. Moreover, Micromodels allow visual access to the displacement process enabling a more detailed process description. Micromodels are generated based on rock images, thus this technology can be applied even if physical core material is not available / accessible.

Why Rock-on-a-Chip Technology?

We design Micromodel chips based on your rock types that:

  • Are cost efficient
  • Are reproducible
  • Require only small fluid volumes
  • Allow control of wettability
  • Reduce the number of required core floods
  • Allow cost efficient EOR process screening
  • Do not require physical core material

This technology provides you with unmatched capabilities to understand your EOR process. Not only recovery factor but in particular pore-scale oil ganglia trapping and mobilisation mechanisms.

The Way to Your Rock on a Chip

We customise the porous structures used for the Micromodel experiments using different sources, including thin section images, μCT images or grain-size distributions to ensure your chips reflect the porosity and permeability of your reservoir.
