Known that solid particles larger than 74 micros
(200 mesh) are classified as API sand. Sand content determination of drilling
fluids is necessary because these sand particles can be highly abrasive, and
can cause damages to pump parts, drill
bits, and pipe connections, excessive sand can result into deposition of a
thick filter cake on the walls of the hole, or it may settle in the hole around
the tools when circulation is temporarily stopped, interfering with the drilling
operation tools of settling casing. The sand content test for set is used in
the test for sand content determination.
EQUIPMENT AND APPARATUS
the content kit are the following tools
Combined funnel with
screen mesh: This is used to conduct already mixed drilling fluid into the
measuring tube. It also serves as a sieve.
Measuring tube: it
divided into 2 levels, which is the mud level and water level. Used for
measuring mud and water.
Mesh: it prevents any
sand that can cause damage from entering into the tube.
Wash bottle: it helps
in washing the sand content left in the measuring tube.

RESULTS AND ANALYSIS
After my experiment was carried out I found
out the percentage of sand content contained in the drilling mud to be 0.3%. This was done with the aid of a
sand content kit.
CONCLUSION AND RECOMMENDATION
To conclude, I will say that the sand
content of any drilling fluid must be known because of that damages that sand
procure to drilling equipment.
The Sand content must not be high so
that it does not affect drilling rate.
