Abstract:
1. A method usable with a well, comprising: deploying a sensing device on a drill string; pumping a drilling fluid within the drill string; pumping a first spacer fluid within the drill string above the drilling fluid; pumping a cement slurry within the drill string above the first spacer fluid such that the first spacer fluid is positioned within the drilling fluid and the cement slurry, the first spacer fluid substantially preventing the drilling fluid from mixing with cement slurry; communicating with the sensing device during a plug cementing operation over a wired infrastructure of the drill string; and controlling the plug cementing operation in response to the communication, wherein the communication includes an identification of an interface of the first spacer fluid and the drilling fluid or an interface of the first spacer fluid and the cement slurry at the sensing device.
