Current through Register Vol. 50, No. 6, June 20, 2024
A. The following
				definitions apply to these terms as used in this Chapter.
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.
