Abstract
Various embodiments include methods and systems structured to provide an indication of the status of a cementing operation in a wellbore. Electromagnetic radiation from a source can be directed to a fluid region in or around a casing in a wellbore, where an electromagnetic response can be detected from interaction of the electromagnetic radiation in the fluid region. Presence or absence of cement in the fluid region can be determined based the electromagnetic response. Additional apparatus, systems, and methods can be implemented in a variety of applications.
