n: the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation.

n: (1) The process of thinning the drilling fluid by bonding with (neutralizing or covering) the positive electrical charges of drilling fluid additives to prevent one particle of drilling fluid from being attracted to another particle. (2) Breakup of flocs

dispersing a clump or a gathering or “flocculated” of particles. Usually accomplished by dispersants or solvent thinners.

n pi: naturally occurring special lignites, e.g., leonardite, that are produced by strip mining from special lignite deposits. Used primarily as thinners and emulsifiers.

n pi: naturally occurring special lignite. e.g., leonardite. that is produced by strip mining from special lignite deposits. The active ingredient is the humic acids. Mined lignins are used primarily as thinners. which mayor may not be chemically modified;however, they are also widely used as emulsifiers.

a fluid without thinners or dispersants.

materials that change the relationship between solids and viscosity of a fluid to lower the gel strength, yield point, yield strength or viscosity as it affected by solids.
