High-temperature consistometer RHC-8020

for high-pressure applications

Thickening Time Tests Thickening time of a slurry is calculated to determine the time required to mix and pump the slurry. Mixing time for the volume is estimated from calculated slurry volume and mixing rate. Mixing rate varies from rig to rig, and is dependent on slurry design. Safety time is allowed to account for any shut down or slow mixing rates that may inadvertently occur. HPHT Consistometer The High-Pressure, High-Temperature (HPHT) Consistometer measures cement slurry viscosity or consistency under elevated pressure and temperature conditions. Its primary function is to determine the maximum available pumping time of a cement slurry before the slurry reaches an un-pumpable consistency before setting. While designed for cement slurries, the effects of pressure, time and temperature can also be observed for other fluids, emulsions, dispersions, or slurries under static or dynamic conditions.
