General Information
Introduction
This manual contains installation, operation and maintenance instructions for the Chandler
Engineering Model 3065 Wettability Tester.
Purpose and Use
The Chandler Engineering Model 3065 Wettability Tester is designed to evaluate the water-
wetting capability of spacers and/or pre-flushes designed to water-wet surfaces after these
surfaces have been exposed to non-aqueous fluids, specifically oil- and synthetic-based drilling
fluids. This is accomplished by measuring the electrical conductivity between electrode
surfaces. The Model 3065 also provides all the functionality of the Model 3060 Constant
Speed Mixer.
Description
The Chandler Engineering Model 3065 Wettability Tester has all the features of the Model
3060 Constant Speed Mixer, with the addition of two electrodes in the body of the mixer to
measure the electrical conductance. Additionally, the Model 3065 is equipped with a heating
jacket to allow testing to 194oF.
Oil-external fluids, such as oil- or synthetic-based drilling fluids, are generally not electrically
conductive, whereas water-external fluids are partially conductive. The water-external fluid to
be used in the testing (generally a spacer or pre-flush) is used to establish a reference
conductance using the Span control. The conditioned oil-based/oil-external fluid is placed in
the pre-heated cup and stirred. Water-based/water-external fluid is then added as a titrant
until the digital conductivity meter indicates a stable water-wetting state. In addition to the
digital display, the operator is able to visually ascertain the compatibility of the mud and
spacer during this test, including significant changes in viscosity as the fluids are mixed.
Features and Benefits
•Programmable temperature control
•Easy to operate, easy to clean and maintain
•Both mixer and wettability operations are easily observed via the bright digital displays
at eye level
•Broad range of sensitivity/scalability to accommodate a wide variety of fluid types
•Analog conductance output for data acquisition via a chart recorder or a computerized
system, such as Chandler’s 4270 and 5270 PC based data acquisition systems
•Hardened mixing blades assure long life
•Variable speed control (1,000 to 18,000 rpm)
•Two preset constant speeds (4,000 and 12,000 rpm). The preset speeds can be easily
changed to any value between 1,000 and 18,000 rpm for applications outside API
Spec 10
•Stainless steel container can withstand abrasive action when mixing cement at high
speeds

SECTION 2 – OPERATING INSTRUCTIONS 2-1
Section 2 – Operating Instructions
Sample Preparation for Wettability Test
1. Prepare a mud sample according to instructions from the supplier. Laboratory-prepared
mud samples may require additional preparation such as static aging or hot rolling to more
fully simulate field mud properties.
2. Mix the spacers and/or pre-flush fluids to be evaluated according to manufacturer’s
procedures. A 500 ml sample is normally sufficient to run a single test.
3. Condition all spacer fluids at BHCT (Bottom Hole Circulating Temperature) to ensure
that fluids are stable and all chemicals have been conditioned and are in solution.
Condition fluids under pressure using high-temperature / high-pressure equipment if
conditioning at temperatures above 194oF (90oC). Fluids should be cooled below 194oF
(90oC) before releasing pressure. The Model 3065 Wettability Tester has been designed
for use at atmospheric pressure. Test temperature should not exceed 194oF (90oC).
Model 3065 Wettability Test Procedure
Note: The span should be adjusted with the spacer fluid being tested before each test
(steps 1-7).
1. Turn Master switch to the On position.
2. Turn Heater switch to the On position.
3. Set the desired temperature using the temperature controller.
4. Preheat cup to desired test temperature.
5. When the water reaches the desired temperature, pour it out and place enough pre-heated
spacer in the cup to reach 1” above the electrodes.
6. With the mixer set in VAR position and the Auto/Manual switch in Manual position, set
the mixer to stir the spacer at a moderate speed (~1000 RPM).
7. Adjust the span to 1.0 (or desired reading for test).
8. Turn off heat to the test cup.
9. Remove the spacer fluid, clean and dry cup and return to base. The meter should read 0.
10. Refill the cup with hot water and stabilize the temperature again before proceeding to the
actual test.
11. When temperature is stabilized, pour out water. Replace immediately with pre-heated
drilling fluid (400mls recommended) in the test cup.
12. Stir at constant rpm (1000 rpm recommended).
13. Add pre-heated spacer at defined intervals until the target reading is obtained (the target
reading is the reading the span was adjusted to in step 7). Monitor fluid temperature with
a thermometer.
14. Record amount of spacer added.
15. Report results as volume percentage of spacer in the mud-spacer mix (see equation below)
that exhibits conductivity measurements indicative of maximum water wetting. (i.e.
maximum water wetting is achieved when the target reading obtained equals the reading
the span was set to at the onset of the test.)
Volume % Spacer = (Total volume of spacer / (Total volume of drilling fluid + spacer)) *100

2-2 SECTION 2 – OPERATING INSTRUCTIONS
Mixing a Cement Slurry
1. Measure the amount of water and pour into the mixer cup. Place the cover on the mixer
cup.
2. Using a scale, measure the amount of cement.
3. Set the Timer Switch to the AUTO position.
4. Verify that the total countdown time is set to 50 seconds in accordance with the API
procedure. Adjust the timer by pressing the small buttons below each digit.
5. Turn the MASTER switch to ON (red power light lit). Press the Mix 1 button.
6. Press the Red START/RESET button. The motor will operate at 4,000 rpm.
7. Add the measured cement into the mixer cup as the water is mixed.
8. Replace the mixer cup cover and press the MIX 2 button to increase the motor speed to
12,000 rpm. The motor will turn off when the timer countdown has ended.
Note: Mixer should run for 15 seconds at LOW speed (4,000 rpm) and the remaining 35
seconds at HIGH speed (12,000 rpm) in accordance with API Specification 10.

Cleaning and Service Tips
Most of the problems that occur with the Model 3065 Wettability Tester are due to
inadequate cleaning. The blade assembly, mixing cup, and probe leads must be thoroughly
cleaned after each test. If the blade assembly becomes contaminated with cement, the
assembly will bind causing the motor to over heat. Care should be taken to clean between the
heating jacket and cup if fluid is spilled or splashed.
First remove the nut on the bottom outside with a 7/8" socket. Pull the blade assembly
through the cup. Remove the small "acorn" nut with a 3/8" wrench. Replace the blade with a
new one. Tighten acorn nut onto new blade. Re-insert the blade assembly through the cup.
Tighten the nut on the bottom outside.
Calibration Procedure
Thermocouple
1. To check thermocouple calibration, heat water in the mixing cup to 100oF.
2. Using a NIST traceable thermometer, check that the temperature is actually 100oF +/- 3oF.
3. Repeat at 175oF.

Section 4 –Troubleshooting Guide
Problem Solution
Faulty motor 1. Remove the mixing cup from the motor.
2. Place the AUTO/MANUAL switch in Manual.
3. Push the VAR button in.
4. Rotate VARIABLE SPEED control counterclockwise.
5. Turn the MASTER switch to ON. Motor should not
be turning or should turn at a very low speed (<100
rpm). Motor speed should increase to 16,000 rpm
when knob is in full clockwise position.
Faulty tachometer Some apparent malfunctions of the tachometer may be
caused by other components:
1. The tachometer indication is zero and the mixer is
running properly.
2. The tachometer reads zero and the mixer is running at
very high speed (greater than 12,000 rpm).
3. The tachometer reads zero or is erratic and the mixer
speed oscillates over a wide range (greater than +/- 200
rpm).
If these symptoms are present, the cause of the problem
will most likely be found in the speed transducer circuit.
1. To verify that the tachometer is working properly,
connect a 6000 Hz 0.5 vdc square wave signal to the pins
of the transducer cable connector. The tachometer
should read 1000 rpm. If reading does not indicate the
correct value, the tachometer should be repaired or
replaced.
Faulty transducer With the motor running, the tachometer will indicate the
RPM of the motor. If the tachometer is known to be
functioning properly but indicates zero RPM when the
motor is turning, the transducer may be faulty or in need
of adjustment. Most common symptoms of a faulty or
misadjusted transducer are:
1. A zero RPM indication
2. The motor runs at very high speed (usually greater
than 12,000 RPM).
3. The Control Enclosure cannot control the speed of the
motor.
4. To verify the transducer is faulty, disconnect the
transducer cable from the Control Enclosure. Measure
the voltage at the two pins on the connector at the end of

4-2 SECTION 4 – TROUBLESHOOTING GUIDE
the cable. The peak-to-peak voltage should be at least
0.4 V and may be as high as 3 to 5 V depending on the
motor speed. If the voltage is too low or not present, the
possible causes are:
Open or shorted cable
Failed transducer
Transducer is not positioned properly
Check the resistance between the two pins in the
transducer connector. If the resistance is less than 200
ohms, the transducer may be good. Note that the 3065
Wettability Tester requires a very small clearance between
the transducer and the gears for proper operation. If the
resistance is greater than 200 ohms, there may be a
broken wire or the transducer may be damaged. Contact
Factory for assistance.
Faulty Timer The timer normally has closed contacts at terminals 1 and
4. Terminal 1 is ground. When the timer is off, terminal
4 is also grounded. When the timer is on, terminal 4 will
have a DC voltage between 0 and 15 vdc depending on
the speed setting of the mixer.
Faulty SCR/Voltage Regulator
Module
If the SCR/Voltage Regulator module is suspected to be
faulty, check the fuse under the SCR/Voltage Regulator.
Replace it if it has failed. If fuse fails repeatedly, the
SCR/Voltage Regulator may be bad. If fuse is OK,
proceed as follows:
1. Set the VARIABLE SPEED control knob to its full
counterclockwise position. The motor will not turn or
turn very slowly (less than 100 RPM). Slowly rotate the
control clockwise. After the control is rotated about 30
degrees, the motor will start turning. The motor speed
should be smooth at speeds less than 3000 RPM. As the
VARIABLE SPEED control knob is turned, the motor
speed should increase smoothly and continuously from
less than 3000 RPM to greater than 16,000 RPM as the
control is rotated.
2. If the motor does not rotate or change speed
smoothly, the VARIABLE SPEED control potentiometer
or the SCR/Voltage Regulator is faulty.
Faulty Speed Control Board Eliminate all other possible sources of the problem before
replacing the speed control board. If the problem
persists, replace the speed control board.

SECTION 4 – TROUBLESHOOTING GUIDE 4-3
