Dispersants, Thinners & Deflocculants

These chemicals modify the relationship between viscosity and the percentage of solids in a drilling mud, and may be used to reduce gel strength and increase a fluid’s pumpability. Thinners function as a deflocculant to reduce attraction (flocculation) of clay particles which causes high viscosity and gel strengths.
