Abstract
Fiber laden fluids may be used to separate two wellbore-service fluids as they travel through a tubular body, preventing their commingling. Such fluids obviate the need for mechanical devices such as wiper plugs, or special adjustment of the wellbore-service fluids' rheological properties. The wellbore-service fluids may be drilling fluids, spacer fluids, chemical washes, cement slurries, acidizing fluids, fracturing fluids, formation-consolidation fluids or gravel-pack fluids.
