New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 3 - RADIATION PROTECTION › Part 12 - LICENSES AND RADIATION SAFETY REQUIREMENTS FOR WELL LOGGING › Section 20.3.12.7 - DEFINITIONS

Current through Register Vol. 35, No. 13, July 16, 2024
As used in this part, the following definitions apply.
A. "Energy compensation source" (ECS) means a
				small sealed source, with an activity not exceeding 100 microcuries (3.7
				megabecquerels), used within a logging tool, or other tool components, to
				provide a reference standard to maintain the tool's calibration when in
				use.
B. "Field station" means a
				facility where radioactive sources may be stored or used and from which
				equipment is dispatched to temporary job sites.
C. "Fresh water aquifer" means a geologic
				formation that is capable of yielding fresh water to a well or
				spring.
D. "Injection tool" means a
				device used for controlled subsurface injection of radioactive tracer
				material.
E. "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.
F. "Licensed material"
				means byproduct, source, or special nuclear material received, processed, used
				or transferred under a license issued by the department under this
				chapter.
G. "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 20.3.12.14
				NMAC.
H. "Logging supervisor" means
				the 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 department's
				regulations and the conditions of the license.
I. "Logging tool" means a device used
				subsurface to perform well logging.
J. "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.
K.
				"Radioactive marker" means licensed material used for depth determination or
				direction orientation. For the purposes of this part, this term includes
				radioactive collar markers and radioactive iron nails.
L. "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.
M. "Sealed source" means any licensed
				material that is encased in a capsule designed to present leakage or escape of
				the licensed material.
N. "Source
				holder" means a housing or assembly into which a sealed source is placed for
				the purpose of facilitating the handling and use of the source in well logging
				operations.
O. "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.
P. "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.
Q. "Temporary job site" means a location
				where licensed materials are present for the purpose of performing well logging
				or subsurface tracer studies.
R.
				"Tritium neutron generator target source" means a tritium source used within a
				neutron generator tube to produce neutrons for use in well logging
				applications.
S. "Uranium sinker
				bar" means a weight containing depleted uranium used to pull a logging tool
				toward the bottom of a well.
T.
				"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 oil, gas, mineral,
				groundwater or geological exploration.
U. "Well logging" means all operations
				involving the lowering and raising of measuring devices or tools which may
				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.
