High Pressure Rheometer

Manufacturer: Vinci Technologies
Model Number: RHEO-1000

The RHEO 1000 is a computer-controlled rotational rheometer based on the Taylor-Couette flow, which is specifically designed to measure the rheology properties of a live oil sample at various conditions of pressure, temperature, chemical composition and shear rate. It can simultaneously mimic the deposition process of wax/asphaltene according to real production shear conditions while measuring the rheological properties of the sample. The instrument provides fruitful information when used with petroleum fluids containing either solid waxes or asphatene particles. Those fluids deviate from Newtonian to non-Newtonian behaviour as soon as solid particles precipitate in the fluid. Such precipitation has a tremendous impact on the rheological behaviour of the oil. It becomes then necessary to characterize the fluid when it exhibits a non-Newtonian behaviour with true conditions of pressure, temperature and shear rate. The Rheo 1000 is the perfect high pressure rheometer tool to accomplish this task.
