Intro 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 placement, begins
to develop compressive strength. However, if insufcient 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 considerable time to
cure, consume valuable rig time, which is also quite costly. Laboratory tests
should be conducted under simulated reservoir conditions to examine the
actual thickening time of the slurry. The OFITE HTHP Consistometer was
specically 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 prole, 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.

Setup
Consistometer
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 grounded.
Make the necessary electrical connections in accordance with local
codes.
6. Connect the cell cap to the winch:
a. With the supplied allen key, unscrew and remove the hex screw from
the winch clasp.
b. Remove the cell cap and support it on blocks above the test cell.
c. Attach the winch clasp to the cell cap and secure it with the hex screw.

7. To ll 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.

8. 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, rell it with mineral oil.
The lubricator has been adjusted at the factory. Under normal operation,
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 discharge.
Rotate the screw clockwise to decrease the oil ow rate and counter
clockwise to increase it.
