The sand content kit is a simple, accurate and inexpensive sieve analysis apparatus for determining the sand content of drilling muds
Sieve analysis is the preferred method for sand content determination because of the reliability of the test and simplicity of equipment. The volume of sand, including that of void spaces between grains, is usually measured and expressed as a percentage by volume of the drilling fluid.
Sand content is the volume percentage of particles larger than 74 microns. Periodic determination of the sand content in a drilling fluid is desirable. Excessive sand may result in the deposition of a thick filter cake on the wall of the borehole, in turn it may settle in the hole around the tools when circulation is stopped and may cause interference with the successful operation of drilling or when the casing is set. High sand content also causes excessive abrasion of pump parts and pipe connections.
