what is slurry in cement
Primary cementing and Secondary Cementing
The cement slurry can be placed behind the casing using low or high injection pressures Low-pressure placement Low-pressure squeeze is the injection of cement slurry into zones at pressures below the fracture pressure of the formation. This technique is mainly used to fill perforation cavities or interconnected channels.
