• Oil & Gas Industry Additives for Cementing

PNS (Poly Naphthalene Sulfonate)

• Polynaphthalene Sulfonate, Polyβ-naphthol Sulfonate, and Polymelamine Sulfonate are all examples of commonly used dispersants. These dispersants function by repelling particles and keeping them suspended in the cement slurry. Still, they have different chemical structures and may exhibit different levels of effectiveness depending on the specific application.

  In addition to reducing viscosity and improving pumpability, dispersants can also improve fluid loss control and prevent the formation of channels in the cement sheath. This can help to ensure proper zonal isolation and reduce the risk of unwanted fluid migration.

  The use of dispersants in oil well cementing and fluid loss control systems can improve the quality and reliability of the cementing operation by ensuring proper placement and preventing issues such as lost circulation and poor zonal isolation.
