Micro-CT Imaging

At Piri Technologies, six (6) state-of-the-art high resolution (to 700nm) Micro-CT scanners are coupled with a three-phase fluid delivery systems to perform flow experiments in different samples with various geological and geometrical properties. The system can be used to investigate multiphase flow in porous media, characterize the associated phenomena and finally map the pore network, fluid occupancy and interfacial areas. A novel core holder design allows flow experiments through small core samples (1-12mm) under confining stress inside the micro-CT scanner. The core flood system is designed to inject three phases with very small flow rates (Down to 0.0001 cc/min) with constant back pressure regulation at controlled pressure and temperature conditions. This equipment also has the ability to measure and monitor flow parameters such as gauge and differential pressures, flow rates, temperature and viscosities.  The scanners incorporate helical scanning technology which allows scientists to obtain artifact-free continuous data sets of very long core samples. This enables imaging of in-situ flow and fluid occupancy within core samples without losing sample area due to limitations associated with the traditional circular CT scan. These systems are used for a wide variety of experimental research to assist customers in reservoir or fluids evaluation as well as in-situ materials analysis.
