Abstract
The problem of fiber or particle settling in well cement slurries is addressed by providing a fluid containing two fiber components of differing properties. Such a well treatment fluid, comprising a base fluid; a first fiber component that it substantially more dense than the base fluid; and a second fiber component that has a density close to that of the base fluid and is relatively flexible.
