n: see radioactive tracer.

n: an isotope of the element iodine, which is radioactive and which is sometimes used as a radioactive tracer.

applying a washable or non-washable radioactive tracer to equipment or proppant to allow tracking of position of the tagged item in the well. Can be used to determine if radioactive tagged sand entered the formation at a specific set of perforations.

n: a radioactive material (often carnotite) put into a well to allow observation of fluid or gas movements by means of a tracer survey.

n: a kind of radioactive substance added into the cement slurry or well ,used as detection sign during tracer survey.

a very low strength radioactive isotope used to tag water or other fluid for tracing the path of fluid in the reservoir or in a well.

n: oil well cement with radioactive tracer ,able to detecte the cement out of the casing or the snubbing cementing situation and the leaker on the casing

a log device that emits a burst of tracer and tracks its movement. May “see” a foot or so outside casing in good circumstances. Normal for injection wells.

n: a survey that uses a radioactive tracer such as a gas, liquid, or solid having a high gamma ray emission. When the material is injected into any portion of the wellbore, the point of placement or movement can be recorded by a gamma ray instrument. The tracer log is used to determine channeling or the travel of squeezed cement behind a section of perforated casing. Also called tracer survey.

a log that uses radioactive tracer to monitor fluid movement in the wellbore or measure losses from the wellbore.

n: A kind of logging ways that using gas ,liquid or solid containning high gamma ray as radioactive tracer.
