During cementing operations, the time required for a cement slurry to set is
of primary concern. Under an ideal situation, minimal time would be
required to successfully pump the slurry, which immediately upon place-
ment, begins to develop compressive strength. However, if insufficient time
is allowed to fully pump the cement, it will be necessary to drill the cement
remaining in the casing string. Remedial operations such as this are very
costly. Conversely, cements that are successfully placed, but require con-
siderable time to cure, consume valuable rig time, which is also quite cost-
ly. Laboratory tests should be conducted under simulated reservoir condi-
tions to examine the actual thickening time of the slurry. The OFITE HTHP
Consistometer was specifically engineered to determine the thickening time
of well cements under simulated downhole pressures and temperatures.

A cement is mixed and poured into the slurry cup assembly. The slurry cup
is placed into the test vessel and pressure is increased via an air-driven
hydraulic pump. A PID temperature controller governs an internal heater,
which maintains the necessary temperature profile, while a magnetic drive
mechanism rotates the slurry cup assembly at 150 RPM. A potentiometer
controls an output voltage, which is directly proportional to the amount of
torque the cement exerts upon an API-approved paddle. A chart recorder
registers cement consistency and temperature as a function of time.
Temperature and consistency are digitally displayed via LED indicators.
