Determination of sand content in a
drilling mud is essential as it will help in preventing any deposition of thick
filter cakes which could damage the formation.

In this experiment, I was able to determine
the sand content of both samples using the sand content kit, and I was able to
obtain the sand composition which are stated above.

DISCUSSION

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

% COMPOSITION OF SAND FOR SAMPLE 2:  0.7

% COMPOSITION OF SAND FOR SAMPLE 1:  0.9

 RESULT

 

 

 

 

 

 

 

 

 

 

After the entire experiment I cleaned my work space.

c.      I ensured the sand
particles settled before taking my percentage composition of sand reading.

b.     I ensured not to spill the
mixed sample in order to ensure accuracy.

a.     I avoided error due to
parallax while taking readings from the cylinder and measuring tube.

 PRECAUTIONS

 

 

12.  
For sample 2, I repeated the same procedure above.

11.  
I allowed the particles to settle before taking my reading.

10.Then I washed the sand
back into the measuring tube. 

9.     After filtering the mud, I
inverted the screen with a funnel at the bottom.

8.      I rinsed the measuring tube with the wash bottle
until it was clean.

7.     I poured the mixture into
the sieve and discarded the filtrate.

6.     I shook both vigorously
until everything is mixed together.

5.     Using the wash bottle, I
filled the measuring tube with water until it reached the water mark.

4.     I poured the mixture into
the measuring tube until it reached the mud mark.

3.     I mixed them with the
electric mixer until I had smooth mud.

2.     I added 35g of bentonite
into the mixing cup along with the measured water.

1.     I measured 350ml of water
in the measuring cylinder.

d.     Wash bottle: this is used
to add water to the measuring tube and sieve.

c.      Funnel

b.     Sieve or screen

a.     Measuring tube: this has

EXPERIMENTAL APPARATUS

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The purpose of this experiment is to determine the percentage
composition of sand in Bentonite mixed with water alone (sample 1) and bentonite
mixed with barite and water alone (sample 2). The equipment used to achieve
this, is the sand content kit.

Estimation of the sand content in a drilling mud is very
important because having a high sand content in your mud can pose serious
problems to the formation. This could lead to deposition of deep filter cakes
on the formation and can damage the drilling equipment through excessive
corrosion.
