Spacer Fluids

Spacer fluids are used to separate drilling fluids and cementing slurries by preparing both pipe and formation for cementing operations.  The spacer fluid system includes a viscosifier, wetting agent, surfactant package, and carrier fluid, typically water.  BASF offers a formulated surfactant package that may be used as part of a spacer fluid system for a wide range of oil-based muds.  The primary function of the surfactant package is to alter the formation surface from oil to water wet, thus, improving cement bonding.
