Cementing plugs are used to remove the mud during cementing operations. Top cementing plugs and bottom cementing plugs are used in the cementing process. The top and bottom cementing plus general have different colors (bottom plugs are red and top plugs are black) in production for easy usage in operation. The top cementing plug has a solid body that provides positive indication of contact with cementing floating collar and bottom plug through an increase in pump pressure. The bottom cementing plug with a hollow body is installed ahead of the cement slurry to minimize contamination by fluids inside the casing prior to cementing.
