X-Ray computed tomography (CT) scanner


The X-Ray computed tomography (CT) scanner delivers high-quality, in-situ saturation profiles of single and multiphase core samples as well as their properties. The apparatus can directly perform scans on exposed, whole core samples retrieved from the well or it can be coupled to a Vinci core flooding system, thereby enabling live visual monitoring of core flooding and Enhanced Oil Recovery (EOR) studies. In other words, the device has the ability to construct 3D and multiplan representations of single and multiphase flow in porous media at reservoir-representative pressure and temperature conditions. Specifically, the determined rock properties are porosity and saturation profiles. In core flooding experiments, a core sample, fitted into a Viton sleeve is loaded in an X-Ray transparent core holder. The specimen is then subjected to the desired temperature and overburden pressure conditions, achieved by virtue of a heating mantle embedded in the core holder walls and a closed confining pressure system. The core holder is fastened to the scanner table and a flexible tubing configuration allows its necessary horizontal displacement towards the emitter. Once the setup and preliminary safety measures have been performed, the experiments can be executed from a dedicated PC work station, located outside of the radiation-isolating testing room. The system comprises an X-Ray transparent core holder and a multi-slice, helical X-Ray CT scanner that rapidly acquires a tomographic image of the rock. The device is supplied with a proprietary software that animates the results and displays the chronological sequence of images.
