Illinois Administrative Code › Title 32 - ENERGY › Part 351 - RADIATION SAFETY REQUIREMENTS FOR WIRELINE SERVICE OPERATIONS AND SUBSURFACE TRACER STUDIES › Subpart A - GENERAL PROVISIONS › Section 351.30 - Definitions

Current through Register Vol. 48, No. 28, July 12, 2024
As used in this Part, the following definitions apply:
"Agency" means the Illinois Emergency Management
				  Agency.
"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.
"Field station" means a facility where radiation sources may
				  be stored or used and from which equipment is dispatched to temporary
				  jobsites.
"Fresh water aquifer" means a geological formation that is
				  capable of yielding fresh water to a well or spring.
"Injection tool" means a device used for controlled
				  subsurface injection of radioactive tracer material.
"Irretrievable well logging source" means any sealed source
				  containing radioactive 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.
"Logging assistant" means any individual who, under the
				  personal supervision of a logging supervisor, handles sealed sources or tracers
				  that are not in logging tools or shipping containers or who performs surveys
				  required by Section 351.670.
"Logging supervisor" means an individual who uses licensed
				  material or provides personal supervision in the use of licensed material at a
				  temporary jobsite and who is responsible to the licensee for assuring
				  compliance with the requirements of the Agency's regulations and the conditions
				  of the license.
"Logging tool" means a device used subsurface to perform well
				  logging.
"Mineral logging" means any logging performed for the purpose
				  of mineral exploration other than oil or gas.
"Personal supervision" means guidance and instruction by a
				  logging supervisor, who is physically present at a temporary jobsite, who is in
				  personal contact with logging assistants, and who can give immediate
				  assistance.
"Radioactive marker" means licensed material used for depth
				  determination or direction orientation. For purposes of this Part, this term
				  includes radioactive collar markers and radioactive iron nails.
"Safety review" means a periodic review provided by the
				  licensee for its employees on radiation safety aspects of well logging. The
				  review may include, as appropriate, the results of internal inspections, new
				  procedures or equipment, accidents or errors that have been observed, and
				  opportunities for employees to ask safety questions.
"Source holder" means a housing or assembly into which a
				  sealed source is placed to facilitate the handling and use of the source in
				  well logging operations.
"Subsurface tracer study" means the release of unsealed
				  licensed material or a substance labeled with licensed material in a single
				  well for the purpose of tracing the movement or position of the material or
				  substance in the well or adjacent formation.
"Surface casing for protecting fresh water aquifers" means a
				  pipe or tube used as a lining in a well to isolate fresh water aquifers from
				  the well.
"Temporary jobsite" means any location where licensed
				  material is used or stored for 180 days or less during any consecutive 12
				  months, and not specifically listed on a radioactive material license.
"Tritium neutron generator target source" means a tritium
				  (hydrogen-3) source used within a neutron generator tube to produce neutrons
				  for use in well logging applications.
"Uranium sinker bar" means a weight containing depleted
				  uranium used to pull a logging tool toward the bottom of a well.
"Well" means a drilled hole in which well logging may be
				  performed. As used in this Part, "well" includes drilled holes for the purpose
				  of disposal or oil, gas, mineral, groundwater, or geological
				  exploration.
"Well-bore" means a drilled hole in which wireline service
				  operations and subsurface tracer studies are performed.
"Well logging" means all operations involving the lowering
				  and raising of measuring devices or tools which contain licensed material or
				  are used to detect licensed materials in wells for the purpose of obtaining
				  information about the well or adjacent formations which may be used in oil,
				  gas, mineral, groundwater, or geological exploration.
"Wireline" means a cable containing one or more electrical
				  conductors which is used to lower and raise logging tools in the
				  well-bore.
"Wireline service operation" means any evaluation or
				  mechanical service which is performed in the well-bore using devices on a
				  wireline.
