Pre-flushes and spacers are an important step to achieving zonal isolation in a wellbore. For a cement slurry to create a proper and effective bond, the surface of the casing and formation must be clean of drilling fluids. A spacer is used to displace fluid from the annulus, while a pre-flush is used to thin and diffuse any leftover drilling fluid particles. Both pre-flushes and spacers play fundamental roles in effective cementing operations and successful zonal isolation. Our solutions include:
- Mud displacement pre-flushes and spacers
- Reactive pre-flushes and spacers
- Lost Circulation pre-flushes and spacers
- Pre-flush and spacer additives
