Low-Solids Mud

Definition - What does Low-Solids Mud mean?

Low-Solids Mud is the mud which consists of few solids than conventional clay based mud with the same density and similar use. The maintenance and design of the mud is achieved primarily by substituting polymers for ordinary bentonite clay. The viscosity can either be obtained entirely by using non-treated or premium quality of bentonite along with an appropriate extender polymer. It is a form of water-based mud used to improve the ability of hole cleaning and also the rate of penetration.

Petropedia explains Low-Solids Mud

To use Low-Solids Mud, several chemicals should be added to prolong the formation of clay yield that leads to the decline of total solid content. The mud is capable of improving the overall or complete rate of penetration. If proper chemical extenders are used, they improve the efficiency of solid removal as the polymer with chemical flocculates the drill solids. The mud is very sensitive to the chemical contamination which is one of its disadvantages. The mud is advantageous as it helps in reducing the wear on pump parts and surface equipment by efficiently removing a large amount of drilled solids from the system.
