1. n. [Well Workover and Intervention]

The process of forcing a cement slurry through holes or splits in the casing or liner. Once the slurry encounters a permeable formation, the cement solids are filtered out of the slurry as the liquid phase is forced into the formation matrix in the form of cement filtrate. A properly designed squeeze-cement operation will fill the relevant holes and voids with cement filter cake that will cure to form an impenetrable barrier.

2. n. [Drilling Fluids]

The forcing, by pressure, of cement slurry into a specified location in a well, such as channels or perforations, for the purpose of achieving zonal isolation. Squeeze cementing is a remedial cementing technique used to repair flaws in primary cement or damage incurred by corrosive fluids.
