Dolomite has introduced the new Porous Media Chip, which enables statistically representative modelling of complex porous sandstone rock structures. The chip will find application in academic research (earth science and engineering), the petrochemical industry, environmental testing and groundwater analysis

The chip features an idealised 2-dimensional net like structure of intersecting 100 µm diameter capillaries, forming pore bodies joined by different types of throats. Pore bodies and throats are assigned standard geometries to simplify structural modelling and analysis. The chip can be used in single and multi-phase fluid (oil, water or gas) flow studies through porous media.

The results can be used to estimate and predict the characteristics of soils and rocks. Operating over a wide pressure range up to 30 bar, the Porous Media Chip is compatible with Dolomite’s Top Interface 4-way and Linear Connector 4-way, allowing quick and reliable fluidic connection to 1.6mm OD tubing. Capillary connections can be added to increase the operating pressure up to 350 bar. The Porous Media Chip is also available in quartz for improved optical transmission.
