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.

Operation

The 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.

The data is automatically recorded to a database for future analysis to help predict the cement slurry’s down-hole performance.

Software

The HPHT Consistometer Control Software is the next generation of complete and powerful system control software with a simple and friendly, flexible user interface.
