Represents a critical process in the oil and gas industry, where a cement slurry is squeezed through perforations in casing to create a seal in specific locations, bridging undesired gaps. It is a common misconception that the cement penetrates the pores of the rock. Instead, the cement slurry dehydrates against the formation walls, forming a seal cement filter cake. It must be clear that cement does not infiltrate the pores of the rock. Given that cement slurries have particles with a mean size ranging from 20 to 50 microns, the permeability of the formation must be between 2-100 darcies for cement grains to penetrate the formation successfully.

Reasons for Squeeze Cementing
The necessity for squeeze cementing arises for various reasons during drilling and production phases, including:

Zone Isolation Before Production Perforations: This ensures that specific zones are sealed off before the commencement of production.

Rectifying Faulty or Inadequate Primary Cement Jobs: When the primary cementing job does not meet requirement, squeeze cementing comes to the rescue.

Fixing Casing Leaks: Squeeze cementing is instrumental in addressing any breaches in the casing.

Shutting off Unwanted Reservoir Water or Gas Inflows: To control and stop the unwanted flow of water or gas.

Abandoning Non-Productive or Depleted Zones: When zones become unproductive or depleted, squeeze cementing is conducted to ensure their abandonment
