HPHT Consistometer

Shale Tech Solutions SRL distribuidor exclusivo de FANN para la Argentina

The Model 290 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.


The Fann Model 290 HPHT Consistometer exposes a cement slurry sample to a controlled set of parameters of temperature, agitation and pressure that simulate the down-hole conditions. During a test, these parameters are carefully monitored and precisely controlled by the system software.

A flat panel, High-Resolution, LCD touch-screen provides the interface between the user and the software. The LCD screen provides real-time viewing of temperature, pressure, and consistency data in graphic and text formats. This data is automatically recorded to a database for future analysis to help predict the cement slurry’s down-hole performance.
