Abstract

An apparatus for use in circulating cement in a casing in a wellbore is described having a first component such as a sensor (50) disposed on the casing (20) and a second component (60) such as a detectable device disposed at a fluid interface (16) formed between the cement (12) and a fluid (36). The sensor may be a sensor coil (50) mounted on the perimeter of the lower end of the casing, while the detectable device may be a transponder (60) capable of emitting Radio Frequency Identification signals to the sensor to signal its arrival at the lower end of the casing. The transponder (60) may be encased in a protective covering. Also described is a method of cementing a casing utilizing a first component such as a sensor disposed on the casing and a second component such as a detectable device disposed in the cement.
