RESUMO
A new modular X-ray-transparent experimental cell enables tomographic investigations of fluid rock interaction under natural reservoir conditions (confining pressure up to 20â MPa, pore fluid pressure up to 15â MPa, temperature ranging from 296 to 473â K). The portable cell can be used at synchrotron radiation sources that deliver a minimum X-ray flux density of 10(9)â photons mm(-2) s(-1) in the energy range 30-100â keV to acquire tomographic datasets in less than 60â s. It has been successfully used in three experiments at the bending-magnet beamline 2BM at the Advanced Photon Source. The cell can be easily machined and assembled from off-the-shelf components at relatively low costs, and its modular design allows it to be adapted to a wide range of experiments and lower-energy X-ray sources.
