Cementing Operation

The cement filtrate invades the formation similarly to the mud filtrate, causing formation damage. The cementing operation does not last as long as the drilling. In addition, the cement slurry solidifies within hours. Therefore, the amount of cement filtrate invading the formation is believed to be very limited.
