AES Tech Tip: Sand Content

Another fundamental part of a mud check is the sand content test. Because of its simplicity, it is widely used in the field. In this AES tech tip, we run through the steps and discuss the relationship between high sand content levels and rig equipment performance.

M.3 Procedure
M.3.1 Fill the glass measuring tube with drilling fluid to the “drilling fluid” mark. Add the appropriate
non-aqueous base fluid (diesel, mineral or synthetic base fluid) to the next mark. Close the mouth of the tube
and shake vigorously.
M.3.2 Pour a small quantity of the base fluid through the screen so that the entire surface is wet by the fluid.
M.3.3 Pour the mixture on the wetted screen. Retain the liquid passing through the screen for proper
disposal. Add more base fluid to the tube, shake and again pour through the screen. Repeat until the tube is
clean. Wash the solids retained on the screen with the base fluid to free it of any remaining drilling fluid.
NOTE Do not stir or manually force the mixture through the screen. Tapping the side of the screen holder as the drilling
fluid is added can help the mixture pass through the screen. If water-wet solids appear on the screen, add several drops
of the oil-wetting chemical used in the drilling fluid to smooth out any water-wet solids.
M.3.4 Put the funnel upside down over the top of the screen. Slowly invert the assembly and insert the tip
of the funnel into the mouth of the glass measuring tube. Wash the solids into the tube by adding a small
volume of base fluid or spraying the solids with base fluid from a wash bottle. Allow the solids to settle. From
graduations on the tube, read the volume percentage of sand.
