Energy Compensation Source (ECS)-a small sealed source, with an activity not exceeding 3.7 MBq (100 microcuries), used within a logging tool, or other tool components, to provide a reference standard to maintain the tool's calibration when in use.
Field Station- a facility where radioactive sources may be stored or used and from which equipment is dispatched to temporary jobsites.
Injection Tool- a device used for controlled subsurface injection of radioactive tracer material.
Logging Supervisor- the individual who provides personal supervision of the utilization of sources of radiation at the well site.
Logging Tool- a device used subsurface to perform well-logging.
Mineral Logging- any logging performed for the purpose of mineral exploration other than for oil or gas.
Personnel Supervision- guidance and instruction by the supervisor who is physically present at the jobsite and watching the performance of the operation in such proximity that contact can be maintained and immediate assistance given as required.
Radioactive Marker- radioactive material placed subsurface or on a structure intended for subsurface use for the purpose of depth determination or direction orientation.
Source Holder- a housing or assembly into which a radioactive source is placed for the purpose of facilitating the handling and use of the source in well-logging operations.
Subsurface Tracer Study- the release of a substance tagged with radioactive material for the purpose of tracing the movement or position of the tagged substance in the well-bore or adjacent formation.
Temporary Jobsite- a location to which radioactive materials have been dispatched to perform wireline service operations or subsurface tracer studies.
Tritium Neutron Generator Target Source-a tritium source used within a neutron generator tube to produce neutrons for use in well-logging applications.
Uranium Sinker Bar- a weight containing depleted uranium used to pull a logging tool down toward the bottom of a well.
Well-Bore- a drilled hole in which wireline service operations and subsurface tracer studies are performed.
Well-Logging- the lowering and raising of measuring devices or tools that may contain sources of radiation into well-bores or cavities for the purpose of obtaining information about the well and/or adjacent formations.
Wireline- a cable containing one or more electrical conductors that is used to lower and raise logging tools in the well-bore.
Wireline Service Operation- any evaluation or mechanical service performed in the well-bore using devices on a wireline.
