High Pressure Microscope

Manufacturer: Vinci Technologies
Model Number: HPM

The HPM is designed to visualise accurately the Wax and Asphaltenes precipitation at onset conditions up to 15,000 psi and 200°C. The HPM enables to identify the solid particles and monitor the change in size and morphology of Wax crystals and Asphaltenes solids as a function of temperature, pressure, time and effect of various chemical treatments. The fluid under consideration is homogenized at the desired conditions in the PVT cell and transferred from the PVT cell to the HPM cell at controlled pressure and flow rate. The HPM cell assembly is stabilised at the reservoir temperature and pressure. Subsequently the fluid is depressurized at known pressure decrements, circulated into the HPM cell and any changes in the observed character of the reservoir fluid are recorded in the HPM video camera. The provided software measures the particle size distribution. The HPM system can be delivered as a stand-alone system or as an add-on module to the Fluid Eval system.
