When extremely high-temperature and/or high-pressure viscosity measurements are required,
the OFITE HTHP Viscometer is the solution. This fully-automated system accurately
determines the rheological properties of completion fluids and drilling fluids in
terms of shear stress, shear rate, time, and temperature at pressures up to
30,000 PSI (207 MPa) and temperatures up to 500°F (260°C). An optional chiller is
available for those situations in which the fluid sample needs to be cooled, rather
than heated, further increasing the flexibility of the system.
Like OFITE’s other computer-controlled viscometers, the HTHP Viscometer features
our easy-to-use ORCADA™ software. Using this exclusive software, a computer novice
can operate the HTHP Viscometer, and yet the system is versatile enough for advanced
research and demanding test parameters.
The HTHP Viscometer uses a compass to detect the rotation of a magnet at the top
of the torsion assembly. The influence of the powerful drive magnets inside of the
shield, the earth's magnetic field, the magnetic properties of the shield, spring
non-linearities, magnetic fields and masses in the laboratory, non-ideal fluid flow,
and small geometry variations all combine to make the angle display non-linear if
not compensated. The microprocessor allows for easy compensation for those effects.
