The Permeability Plugging Tester (PPT) is a modication of the standard
500 mL HTHP Filter press. It may be used in the eld or in a laboratory
environment. The instrument is useful for performing ltration tests on
plugging materials without the interference of particles settling on the lter
medium during the heat up process. The PPT is very useful in predicting
how a drilling uid can form a low permeability lter cake to seal off depleted,
under pressured intervals and help prevent differential sticking. Typical
differential pressures are much higher than those seen in standard HTHP
testing.
The pressure cell is similar to those seen in standard HTHP ltration testing,
but it is inverted with the lter medium and the back pressure receiver on
top of the assembly. It is pressurized with hydraulic oil and a hand pump. A
oating piston separates the oil from the test uid in the cell. The cell has a
maximum pressure rating of 6,000 psi.
Both end caps are designed to accept a  " NPT tting. The inlet, or bottom,
cap is tted with a quick-connect for the connection to the hydraulic pressure
manifold. The standard hydraulic pressure manifolds are equipped with a
relief valve.
The LCM receiver is mounted on top of the cell.

Safety Read this manual carefully before attempting to use the equipment. Improper
use can result in injury or damage to the equipment.
Temperature
The heating jacket, test cell, and pressure assemblies will be very hot during
testing. Handle these components with care. Never touch hot components
without wearing protective clothing.
At elevated temperatures, the uid in the test cell will expand. Never ll the
test cell completely with uid. Always leave some void space to allow for
thermal expansion. Refer to page 16 for recommended ll volumes.
Pressure
Always pressurize with either Carbon Dioxide or Nitrogen. Do not use Nitrous
Oxide (NO2), Oxygen (O2), or compressed air. These gasses are dangerous
at elevated temperatures.
The maximum working pressure of the test cell (6,000 PSI / 41.2 MPa) is
marked on the cell body and cap. Never exceed this pressure.
Equipment
Inspect all o-rings before every test. Discard any that show signs of damage
or wear. Looks for nicks, cuts, or brittle o-rings. Two sets of o-rings are
included with the Filter Press. The rst set is made from Viton 75D. These
o-rings are black and should be used for tests up to 400°F only. The second
set is made from Viton 90D. These o-rings are green and should be used for
tests up to 500°F.
Cell Corrosion
Test uids under high tempreature and pressure can corrode the cell body
and caps. Carefully inspect the cell body and calls for corrosion before and
after each test.
Some materials are more susceptible to corrosion than other. Also, some
uids and additives are more corrosive than others. OFITE offers a variety of
cell materials for different levels of corrosion resistance and cost.

Pump
For safe operation of the Hydraulic Pump Pressurization system, make sure
the pressure has been released and the gauge on the pump reads zero before:
1. Attempting to disconnect the pressure hose from the cell at the quick-
connect.
2. Attempting to remove the cell from the heating jacket.
3. Reallocating or moving the PPT in the laboratory.
4. Refilling the hydraulic pump.
5. Performing any maintenance including tightening leaking fittings on the
pump, hydraulic fittings, or cell assembly.
When relling or repairing the hydraulic system, make sure any spilled oil is
cleaned. Oil on the oor is very slippery and can cause falls and injury. Oil
spills on the bench can accumulate and become a re hazard.

Quick Start 1. Place the thermometer in the heating jacket.
2. Preheat the heating jacket to 10°F (6°C) above the test temperature. The
pilot light will turn on at the target temperature.
3. Soak a ceramic disk in base fluid for at least 10 minutes before testing.
4. Inspect all o-rings. Replace any that show signs of damage or wear.
5. Apply grease to all o-rings.
6. Assembly both cell caps and the piston. Place o-rings in the grooves
around the cap and piston.
7. Place an o-ring on the shoulder inside the cell on the end marked “IN”.
8. Apply grease to the threads of the cell caps and valve stems.
9. Screw the inlet cell cap assembly into the cell body and tighten it com-
pletely.
10. Push in the red knob on the heating jacket. Place the cell in the heating
jacket with the inlet side pointing down.
11. Screw the inlet pressure assembly into the inlet cell cap.
12. Screw the t-handle into the piston.
13. Push the piston inside the cell against the inlet cell cap. Tighten the set
screw on the piston bleed valve.
14. Connect the inlet pressure manifold to the inlet pressure assembly.
15. Open the ball valve on the manifold and close the pressure release valve
on the pump.
16. Stroke the pump until the t-handle rises about 1.5" (3.8 cm).
17. Unscrew the t-handle from the piston.
18. Pour the test fluid into the cell all the way up to the o-ring shoulder.
19. Place an o-ring on the shoulder inside the cell body.
20. Place a ceramic disk on top of the o-ring.
21. Screw the cell cap assembly into the cell body and tighten it completely.
22. Connect the LCM bottom cap assembly to the cell cap assembly.

23. Make sure the filter is in place inside the receiver bottom cap.
24. Pour water into the hole in the receiver bottom cap.
25. Open the outlet valve to allow excess water to drain, then close the outlet
valve.
26. Apply grease to the receiver cap o-rings and place one around each cap.
27. Screw the receiver top cap onto one end of the receiver body.
28. Screw the receiver body onto the bottom receiver cap.
29. Screw the valve stem into the port on the receiver top cap.
30. Attach the CO2 Pressure Assembly to the top valve stem and secure it
with a safety pin.
31. Pull out the red knob on the heating jacket and lower the cell. Rotate the
cell until it seats.
32. Move the thermometer to the cell body.
33. Place a CO2bulb in the CO2pressure assembly. Set the pressure to the
appropriate back pressure for your test.
34. Stroke the pump to apply the same pressure to the cell.
35. When the cell has reached the test temperature, stroke the pump to apply
the working test pressure to the cell.
36. Collect filtrate by opening the needle valve on the LCM Receiver.
37. At the end of the test, turn off the heating jacket.
38. Allow the cell to cool.
39. Close the regulator on the CO2pressure assembly.
40. Open the pressure release valve on the pump to release pressure inside
the cell.
41. Unscrew the VCO fitting to disconnect the LCM Receiver from the cell
cap.
42. Disconnect the inlet pressure manifold from the inlet pressure assembly.
43. Remove the cell from the heating jacket and set it upright to disassemble.

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 9
44. Reconnect the pressure manifold to the inlet valve pressure assembly.
45. Remove the outlet cell cap assembly.
46. Remove the ceramic disk and save the filter cake for later analysis.
47. Discard any remaining test fluid.
48. Screw the t-handle into the piston and push the piston to the bottom of
the cell.
49. Close the pressure release valve on the pump and the ball valve on the
pressure manifold.
50. Disconnect the pressure manifold from the inlet pressure assembly.
51. Remove the inlet pressure assembly and inlet cell cap assembly.
52. Clean and dry the entire cell assembly.
