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.

1. Carefully remove the instrument from the wooden crate.
2. Once the unit is in place, lock the casters by depressing the lever on
the side. This will prevent the unit from moving.
3. Connect an air or nitrogen (100 - 150 PSI / 690 - 1,035 kPa) supply to
the air supply on the back of the instrument.
This unit uses ¼” NPT female connectors for all supply lines.
4. Connect the drain and coolant supply lines, also on the back of the unit.
5. Make sure all electrical switches are turned off and the unit is ground-
ed. Make the necessary electrical connections in accordance with local
codes.
6. To fill the oil reservoir, open the front cabinet door and remove the oil
reservoir cap. Using a funnel, pour approximately four liters (or until
full) of mineral oil into the reservoir. Replace the cap. Make sure the
seal is air tight. Use the sight glass on the side of the reservoir to
check the oil level.

7. Periodically inspect the oil level within the air line lubricator. This unit is
located just upstream of the air inlet on the hydraulic pump inside the
Consistometer cabinet. You can access it by opening the cabinet doors
on the back of the unit. If the oil level is low, refill it with mineral oil.
The lubricator has been adjusted at the factory. Under normal opera-
tion, one drop of oil should be discharged into the air stream every 12
to 20 pump strokes. This discharge can be observed through the clear
control needle on top of the lubricator. If adjustment is necessary, turn
the hex screw on top of the control needle until you observe normal dis-
charge. Rotate the screw clockwise to decrease the oil flow rate and
counter clockwise to increase it.
