Excess sand in the drilling fluid can cause a thick filter cake to form on the borehole wall or settle downhole once circulation is stopped. Settled sand can cause problems when operating drilling tools or setting casing. High levels of sand can also cause excessive abrasion of pump parts and pipe connections.
According to the API, sand-sized particles larger than 74 µm are defined as sand. Sand volume, including intergranular voids, is normally measured and expressed as a percentage by volume. Sieve analysis using a sand content kit are the preferred method for determining sand content because the kit is easy to use and the results are reliable.
The Sand Content Kit is used to determine the volume percent of sand in drilling fluids. The Sand Content Kit consists of a sieve of 75 µm, a plastic funnel, a graduated glass tube, and a wash bottle all packed in a small carrying case.
The MUDTEST Sand Content Kit complies with the requirements of API RP 13B-1 or the corresponding international standard ISO 10414 for field testing of drilling fluids.
