Compositions and methods for servicing subterranean wells
Aqueous fluids containing hydrophobic particles are effective media for cleaning water-base drilling fluids and drilling fluid solids from the interior surface of a casing string. Hydrophobic fibers may be added to a drilling fluid, a spacer fluid, a chemical wash, or combinations thereof. The disclosed fluids may be employed during primary cementing operations where it is not possible to use a bottom plug.
