Pumping a cement slurry to a specific point in the wellbore with sufficient pressure to force the cement into the location desired. This pressure will also tend to dehydrate the cement and form a high strength filter cake in perforations, in formation voids or fractures, or against the formation face. The filter cake becomes a barrier which will prevent fluid movement. Squeeze cementing is used to seal completion intervals, to repair casing leaks, to seal formation intervals behind pipe, and to protect fresh water aquifers.
