6.0 PROCEDURE
For viscometer
1. The power supply is first switched on then the mud sample is filled into the mud
cup.
2. The thermocouple is plugged in.
3. The bob is screwed into the bob shaft until it is tight.
4. The sleeve is tightening onto the rotor shaft.
5. The mud sample is placed on the stage by positioning the alignment stem over the
corresponding hole on the stage.
For unit measurement
i. Go button !fter enter the test step" #ress 1.ii. $et up button #ress 2 will display the test set up screen" enter the parameter
for the temperature and rotational speed for the first step of the test. %nter
twice to return to main screen.iii. &eview button !fter running the test" press 3 to allow to allow review the test
result.
'. The speed of the viscometer is set to 3(( rpm and the data is recorded. $tep 1'
is repeated using '(( rpm.
%)perimental procedure
1. ! 4(( ml water based mud is measured in a bea*er.
2. The mud is test for weight" plastic viscosity and yield point using viscometer. The
data is recorded in the table.
3. The water based mud is then divided separately into two different bea*ers with
2(( ml in each bea*er.
4. Then" the bea*er is labeled as +ea*er ! and +ea*er +.
5. Five grams of gypsum is added for +ea*er ! and 15 grams for +ea*er +.
'. The sample is stirred for three minutes using mi)er.
,. The sample is being rest for 15 minutes.
-. $tep 2 is repeated for both +ea*er ! and +ea*er +.
