Abstract
The present invention provides improved traceable well cement compositions and methods. The compositions are basically comprised of hydraulic cement, sufficient water to form a pumpable slurry and a normally non-radioactive tracer compound which becomes radioactive and emits detectible rays over a relatively short time period when exposed to neutrons. The methods of the invention relate to cementing a zone in a well and subsequently detecting the subterranean location of the cement composition therein. A traceable well cement composition of the invention is formed and introduced into a subterranean zone to be cemented. Neutrons are then emitted from a source in the well so that the tracer compound emits detectible rays, the rays are detected and the location of the cement composition in the well is determined.
