At present there is no technology available to monitor cementing operations in real time from the time of placement to the end of the borehole service life. In this study well cement was modified using carbon fibers and other additives to give it better sensing properties, also known as smart cement, so that its behavior can be monitored during the cementing operation and its life time.
