CT Scanner

CT Scanners

X-ray microcomputed tomography (to many known as CT scanning) is an essential technique to determine the interior microstructure of materials in three dimensions or even four if repeated 3D images are collected over time, either in situ (while the development is taking place) or ex situ (stop and go types of measurement). Therefore, the technique allows us to determine the 3D structure of the pore networks in porous reservoir rocks and to see how the pores are changing over time, e.g. when reactive fluids are flowing in through the pores. From the three dimensional microstructure, it is possible to retrieve petrophysical properties of the reservoir rocks and to perform modelling of e.g. fluid flow processes.

At building 375, there are two CT scanners located. One provides a spatial resolution, in volume pixel (voxel) size, down to about 3 µm and the other provides a resolution down to about 0.5 µm. The effective achievable resolution depends on the sample size and sample composition, i.e. the larger the sample, the lower the resolution can be obtained. As a rule of thumb there is a factor of 1000 between the sample size and the needed resolution, i.e. for a 1 inch core plug the voxel size will be about 30 µm.

DHRTC is also member of the 3D Imaging Center (3DIM) at DTU, which means we have access both to the instruments located in Building 310 (that complement our instrument) and the expertise in X-ray imaging and image analysis located within 3DIM.

It is possible for external users to have their sample analysed at DHRTC or 3DIM depending on the project. We can help decide which instrument is suitable for your project.
