Current through Register Vol. 24-14, July 15, 2024
As used in this chapter, the following definitions
				  apply:
(1) "Casing" means a metal pipe
				or tube used as a lining for oil or gas wells to prevent collapse of the
				well-bore.
(2) "Energy compensation
				source" (ECS) means 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.
(3) "Field station" means a
				facility where radioactive sources may be stored or used and from which
				equipment is dispatched to temporary job sites.
(4) "Fresh water aquifer" means a geological
				formation that is capable of yielding a significant amount of fresh water to a
				well or spring.
(5) "Injection
				tool" means a device used for controlled subsurface injection of radioactive
				tracer material.
(6) "Irretrievable
				well-logging source" means any sealed source containing licensed material that
				is pulled off or not connected to the wireline that suspends the source in the
				well and for which all reasonable effort at recovery has been
				expended.
(7) "Logging assistant"
				means an individual who assists the logging supervisor in performing the
				well-logging operations.
(8)
				"Logging supervisor" means an individual who provides personal supervision of
				the use of licensed material at the temporary job site and who is responsible
				to the licensee for assuring compliance with requirements of the department's
				regulations and the conditions of the license.
(9) "Logging tool" means a device used
				subsurface to perform well-logging.
(10) "Mineral logging" means any logging
				performed for the purpose of mineral (including water) exploration other than
				oil or gas.
(11) "Personal
				supervision" means guidance and instruction by the supervisor who is physically
				present at the job site and watching the performance of the operation in such
				proximity that contact is maintained and immediate assistance given as
				required.
(12) "Radioactive marker"
				means licensed material used for the purpose of depth determination or
				direction orientation. This term includes radioactive collar markers and
				radioactive iron nails.
(13)
				"Sealed source" means any licensed material that is encased in a capsule
				designed to prevent leakage or escape of the radioactive material.
(14) "Source holder" means the housing or
				assembly into which a radioactive source is placed for the purpose of
				facilitating the handling and use of such source in well-logging
				operations.
(15) "Subsurface tracer
				study" means, for the purpose of this chapter, the release of unsealed licensed
				material or a substance labeled with licensed material in a single well or
				multiple wells for the purpose of tracing the movement or position of the
				material or substance in the well-bore or adjacent formation(s) (this term does
				not include the use of licensed material in field flooding studies).
(16) "Surface casing" means a pipe or tube
				used as a lining in a well to isolate the fresh water zone from the
				well.
(17) "Temporary job site"
				means any location to which radioactive materials have been dispatched or taken
				to perform wireline service operations or subsurface tracer studies.
(18) "Tritium neutron generator target
				source" means a tritium source used within a neutron generator tube to produce
				neutrons for use in well-logging applications.
(19) "Uranium sinker bar" means a weight
				containing depleted uranium used for the purpose of providing additional force
				to pull a logging tool down toward the bottom of a well.
(20) "Well-bore" means any drilled hole in
				which wireline service operations and/or subsurface tracer studies are
				performed.
(21) "Well-logging"
				means the lowering and raising of measuring devices or tools which contain
				sources of radiation into well-bores or cavities (salt domes, etc.) for the
				purpose of obtaining information about the well and/or adjacent formations
				which may be used in oil, gas, mineral or geological explorations.
(22) "Well-logging operation" means any
				activity involving licensed material performed in a well, including
				well-logging, mineral logging, subsurface tracer studies, use of radioactive
				markers, radioactive iron nails, uranium sinker bars, and radioactive sands,
				and transportation or storage of same.
(23) "Wireline" means a cable containing one
				or more electrical conductors which is used to lower and raise logging tools in
				the well-bore.
(24) "Wireline
				service operation" means any evaluation or mechanical service which is
				performed in the well-bore using devices containing radioactive material on a
				wireline.
