Sodium Chloride (NaCl)AcceleratorSodium chloride (NaCl), commonly known as salt, can beused in low concentrations to accelerate the setting ofcement. In high concentrations, NaCl retards the setting ofmost cements, improves bonding of cement to shales, andminimizes damage in zones sensitive to fresh water. Adefoamer should be added to dry blends or to mixing waterto minimize foaming and air entrainment.

Features

Sodium chloride is a crystalline solid additive used in oilwellcementing applications. NaCl will not accelerate aseffectively as calcium chloride (CaCl2); however, NaCl maybe more readily available. NaCl salt is applicable over atemperature range of 50° to 500°F (10° to 260°C). NaCl hasthe following effects on slurry properties:

• It decreases viscosity and thickening times at lowconcentrations and increases final strength.

• It increases density and water loss.

Benefits

When used for oilwell cementing, NaCl can provide thefollowing benefits:

• Increased final strength

• Accelerated setting

• Better cement bonding to shales

• Reduced damage to water-sensitive reservoirs
