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 insufcient 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 Benchtop Consistometer
was specically 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 prole, 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
Eurotherm
The Eurotherm Model 3504 controls the temperature and displays the
pressure. When running a test with the computer, the software automatically
programs the controller. However, when running a test without the computer,
the controller must be programmed manually. It is strongly recommended
that operators carefully study the Model 3504 instruction manual before
attempting to program the controller.
When running a test without the computer, always build the program prior to
mixing the slurry and loading the slurry cup.
The Eurotherm 3504 can store up to eight custom programs. Each program
consists of multiple segments. In a segment, the temperature setpoint can be
changed or held for a certain amount of time.
Each program also can consist of two channels; one for temperature and one
for pressure. Since the Benchtop Consistometer does not offer automatic
pressure control, only Channel 1 should be programmed.

a. Set the following parameters for each test:
- Ramp Units: Seconds, Minutes, Hours
- Cycles: The number of times to repeat the test.
b. You must choose a Segment Type for each segment in the test.
The Segment Type will determine the parameters available for that
segment:
Rate: Increase the setpoint by a certain rate (Ramp Rate)
- Target SP: The end temperature for the segment
- Ramp Rate: The rate of increase for the setpoint. For example,
if Ramp Units is set to minutes, and Ramp Rate is set to 5, the
temperature setpoint will increase by 5° per minute.
Time: Increase the setpoint over a certain time (Ramp Time)
- Target SP: The end temperature for the segment
- Duration: The amount of time it will take to increase the setpoint to
the target.
Dwell: Hold the current setpoint.
- Duration: The amount of time to hold the current setpoint.
Step: Increase the setpoint immediately. No ramp is involved.
- Target SP: The end temperature for the segment.
End: The nal segment in every test must be End.
- End Type: Dwell is recommended. This will hold the current
setpoint until the test is stopped.
The display is split into two areas. The top area shows the temperature
channel while the bottom shows the pressure channel. Before starting a
manual test, the temperature channel must be in auto mode and the pressure
channel must be in manual mode:
