Abstract
An aqueous-based well treatment fluid containing an additive having a median particle size less than 1 micron is suitable for use in a wide variety of well treatment applications including use as a drill-in fluid, thermal insulating fluid, spacer or fluid loss control additive. The fluid may consist of a high density brine. The additive is capable of viscosifying the water or brine. Viscosification of the water or brine may occur in the substantial absence of a polymeric viscosifying agent.
