SCHLUMBERGER SAFETY POLICY The following paragraphs are excerpts from the Schlumberger SLfety Practices manual.
These paragraphs define Schlumberger safety policy as it pertains to working conditions, management responsibilities, and safety violations.
This policy applies to all Schlumberger operations, including those operations involving the use of radioactive materials.
Schlumberger will provide every employee with safe and healthful working conditions.
Preventing accidents, loss or damage of equipment, personal injury of our employees, customers, and the general public are operating responsibilities of every manager.
OV Managers will be evaluated on their performance in accident prevention and safety promotion.
Managers are expected to familiarize themselves with and train their employees to understand the rules, laws, regulations, and standards as set forth by Schlumberger and the regulatory i
agencies. It is the obligation of all employees to comply with these rules, laws, regulations, and standards.
Violation of safety regulations may constitute cause for discharge or other disciplinary action.

USE OF RADIOACTIVE MATERIAL SOURCE MATERIAL Five (5) radioactive materials are used in Schlumberger sources. These materials are:
241 Isotope:
Americium Beryllium (AmBe-241) 241Americium powder is combined with Beryllium powder, pressed into a pellet, and encapsulated in metal.
IIalf life......................... 45 8 years Emission (from encapsulation)...........ncutrons with low energy gammas Chemical or physical form............ Americium Oxide and Beryllium in pellet form 137 Isotope:
Cesium (Cs-137) 137Cesium is a fission product.
The Cesium is entrapped in ceramic and fabricated into a capsule.
H alf life......................... 3 3 years Emission (from encapsulation)...........high energy gamma Chemical or physical form............. Cesium entrapped in ceramic 60 Isotope:
Cobalt (Co-60) 60 59 Cobalt is produced by neutron bombardment of Cobalt metal foil or wire.
The specific activity can vary over a wide range, depending on the neutron flux and irradiation time.
IIalf life......................... 5.2 years Emission (from encapsulation)........... gamma (7
Chemical or physical form............. metal
/
_)
11-1
226 r'% -
()
226 Radium is encapsulated in metal. Most of the gamma rays are emitted by 226 decay products rather than by the parent Radium, which is primarily an alpha emitter.
IIalf life......................... 159 0 years Emission (from encapsulation)........... gamma Chemical or physical form............. radium salts 232 Isostope:
Thorium (Th-232) 232Thorium is an alpha emitter with gamma rays being emitted by the decay products.
10 IIalf life......................... 1.4 x 10 years Emission.......................... alpha, gam m a, and beta Chemical or physical form.......... mixture of thoriated sand and plastic formed into a sheet RADIOACTIVE SOURCES USED BY SCHLUMBERGER Logging Sources There are two types of logging sources: gamma ray emitting and neutron emitting. The source is placed in a well logging tool and lowered into a wellbore. Gammas or neutrons are emitted into the subsurface environment and detectors in the tool measure the effect of the environment on these emissions. The Schlumberger engineer can interpret this information to determine the formation characteristics necessary to the oil and gas industry.
l Calibration Sources These sources are also either neutron emitting or gamma emitting, but they have a much lower strength.
II-2
Source Accesories Each logging source has a specially designed pressure vessel and carrying shield.1 The pressure vessel is a source holder designed to withstand hydrostatic pressure in the wellbore. The carrying shield is designed to keep the radiation level within regulatory standards.
Beyond this, the shield is designed in accordance with the concept of "ALARA" (as low as reasonably achievable).
During transportation and storage, the carrying shield provides an optimum safety level for our employees and the gencral public.
Calibration sources do not require pressure vessels because they are not used in a downhole environment. Because their radiation level is extremely low, most calibration sources do not require carrying shields.
Project Codes Schlumberger uses its own system of project codes, which is an alpha designation of each device. Each sourec, empty pressure vessel, and empty carrying shield has a specific alpha project code.
In addition, each source / pressure vessel combination or source / pressure vessel / carrying shield combination has a specific alpha project code.
Cs'g' 137 For example: The GSR-B is a 1.5 curie Cesium logging source. The pressure vessel used with this source is a GPV-A. When the GSR-B source is placed in the GPV-A pressure vessel, the combination is called a GPV-AB. The GCS-H is the appropriate carrying shield for this source. When the GPV-AB source / pressure vessel combination is placed in this carrying shield, the source / pressure vessel / shield combination is called a G LS-AB.
Thus, the project code not only designates a particular source, but also specifies the exact source / pressure vessel / carrying shield combination.
Each calibration source has an alpha code designation for the source itself. But, since most calibration source. do not requite pressure vessels or carrying shields, the alpha designations are not complicated by combination codes.
O)
I
's There is one exception: the GSR-F is a low strength logging source that does not
~
require a pressure vessel or carrying shicld.
11-3
AV OTHER RADIOACTIVE MATERIAL Some Schlumberger Districts also use minitron tubes, PIP tags, and tracer material.
Minitron Tubes A minitron tube is a particle accelerator that yields 14 MeV neutrons when it is operating. The minitron tube contains deuterium and tritium, which are adsorbed onto the tube filament. When the tube is activated, a small current heats the filament and the gases are released into the tube. When a short-duration control pulse is applied to a ring magnet surrounding the gases, the gases are ionized. At the same time, a high negative voltage is applied to a target located at the other end of the tube. The positive ions produced by the deuterium and tritium bombard the target, generating a nuclear reaction.
During logging, we require the tool to be 100' below the surface before the minitron tube is turned on. Surface testing must be performed inside an SFT-126 tank. This tank is p
filled with water or diesel fuel, and provides some shielding around the perimeter of the V
tank. However, during testing the area surrounding the tank should be controlled.
At all other times, the tube is effectively in an "off" state, and is not a neutron source.
Thus, most of the regulations discussed in this book do not apply to minitron tubes.
Precision Identified Perforation Tags (PIP Tags) 60 PIP tags are made of Cobalt, which is primarily a gamma emitter. PIP tags are used to identify areas within the wellbore. A PIP tag is put on a perforating charge. When the charge is shot, the radioactive material is deposited in the formation.
The radioactive material can later be detected, allowing the location of the perforating shots to be pinpointed.
Figure Il-1 A shows a strip of five (5) PIP tags. Tags are received in this manner. Figure II-1B shows a single PIP tag that has been peeled from the strip. In this manual, the term
" PIP tag" describes one tag, as shown in figure 11-18.
O II-4
.. = -
!l PIP tags have a very low radiation level. But, since they do contain radioactive material, V
some of the regulations discussed in this manual will apply to PIP tags.
PIP tag regulations vill be discussed as a separate subheading in each applicable section.

Figure ll-1 A Figure Il-1B Tracer Material Tracer material is radioactive fluid that is injected into a wellbore - usually an injection well. The trer. sit time of the fluid is measured to determine the flow rate through the wellbore environment. One of several isotopes may be used, depending on conditions.
Each of the isotopes has a half-life measured in days.

O ADMINISTRATION AND CONTROL OF RADIOACTIVE MATERIAL This manual discusses the regulations governing the use of radioactive material by the Schlumberger Districts. It must be noted, however, that control records are maintained on a company-wide level.
Thus, each District's control of radioactive materials is monitored. This section explains the company-wide control process.
LOGGING AND CAllBRATION SOURCES Specific departments at Headquarters are responsible for purchasing, testing, and shipping new radioactive sources to the Districts.
\\" hen a new source is received, it is entered (with description and serial number) into the RADIATION SOURCES CONTROL listing. When the source is shipped to a District, it is reassigned to that District on the RADIATION SOURCES CONTROL listing.
Anytime a source is transferred between n
Districts, it is also reassigned on the RADIATION SOURCES CONTROL listing. Field locations order radioactive sources (or equipment containing radioactive sources) through the Schlumberger Headquarters offices in Houston, Texas.
Each District is responsible for maintaining inventory records of its sources.
The District is also responsible for verifying source shipments. When a source is shipped from the Warehouse, a card is mailed to the District that placed the order. This card identifies the source by serial number, and gives the date the source was shipped. The District must return the card to Headquarters when the source is received, or notify lleadquarters if the source has not been received within normal transit time.
A field location retires a source by shipping it back to Headquarters.
OTHER RADIOACTIVE MATERIALS Minitron Tubes Minitron tubes are ordered and controlled in the same manner as loggir.g and calibraticn sources.
V 111-1
k PIP Tags PIP tags are bought by the Districts directly from a licensed supplier. Each District is responsible for maintaining PIP tag records. Unwanted PIP tags are returned to the supplier, or a licensed facility, for disposal.
Tracer Material l
Tracer material is bought by the Districts directly from a licensed supplier.
Each i
District is responsible for maintaining records of all tracer material. Each District that I
performs tracer services must bring any contaminated material back from the wellsite.
The District must ship the contaminated material to the supplier or a licensed facility for disposal.

n SHIPMENT AND TRANSPORTATION v
OF RADIOACTIVE MATERIAL In the United States, the Department of Transportation (DOT) and state agencies control the shipment and transportation of radioactive sources.
Scope of Dot Regulations The United States Coast Guard, the Federal Aviation Administration, and the Federal Iligi.way Administration are part of the Department of Transportation. Thus, DOT regulations apply to all modes of shipment and transport - via water, air, or land.
DOT regulations are valid only in the United States. The Radiation Safety Officer or the Traffic Control Department, both in llouston, should be consulted before any radioactive materials are exported.
)
Definitions of Shipping and Transport For simplification within this manual, a distinction is made between the meanings of the words " ship" and " transport". A source is considered shipped when it is released to a common carrier (an outside company or individual). A source is considered transported when it is moved by Schlumberger vehicle, under the control of a Schlumberger employee.
Again, these definitions are valid within this manual only. These are not legal definitions
- their only purpose is !o simplify discussion of the reguhtions as they apply to Schlemberger. Most DOT regulations apply to both shipping and transporting. Important distinctions will be made based on the defbitions given above.
TRANSPORTING RADIOACTIVE SOURCES When radioactive sources are transported on Schlumberger vehicles, the following internal Schlumberger procedures must be followed:
O IV-1
The shield must be chained and locked to an integral part of the truck until it is removed for use at the wellsite or storage at the location.
The source must remained locked in its shield when not in use.
SHIPP:NG AND TRANSPORTING RADIOACTIVE SOURCES The DOT regulations controlling the shipment and transport of radioactive sources can be summarized by the following requirements:
Packaging Labels a'id Marks Seals Shipping e'oeuments Placards and signs The specific requirements of each category will be explained in separate subhea:iings.
U Packaging Radioactive sources must be shipped or transported as source packages. The term source package is used to designate a source that is packaged in accordance with DOT requirements. All packages must meet these requirements:
The shielding level at the surface of the package must not exceed 200 mrem per hour.
The shielding level at three feet from the package (transport index) must not exceed 10 mrem per hour.
The package must have no dimension smaller than four (4) inches.
Schlumberger carrying shields are designed in accordance with DOT packaging requirements, according to content. All logging source / pressure vessel / carrying shield combinations meet the DOT packaging requirements. Carrying shields are appropriate packaging for both the shipment and transport of logging sources.
IV-2
l q Most calibration sources do not have specially designed carrying shields because their D
radiation levels are very low. The only additional DOT requirement for the shipment or transport of calibration sources is that cxternal packaging be used to increase the size of the source package up to the four inch minimum, and to eliminate direct handling of the source. Ilowever, normal operating procedures at the Districts are more stringent:
Normally, the GSR-E is transported inside the carrying case (part number 11-245440)
Normally, all other calibration sources are transported inside the calibration jig.
If the District must transport a calibration source without the jig or carrying case, the Unit Safety Engineer should be consulted.
Whan an approved source package is boxed or crated, the source is overpackaged.
Overpackaging is permitted, as long as the box or crate is sturdy enough to support the contents.
O Labels and Marks The appropriate labels and marks must be on all soure2 packages being shipped or transported. Labels and marks must be placed on the outside of the source package -
i.e., on the shield or jig. If overpackaging is used, the DOT LABEL and the appropriate TYPE A or B mark must also be placed on the overpackaging. When a label is available in paper and plastic or metal, the more durable plastic or metallabel is preferred.
The la)els and marks required for each Schlumberger source package are summarized as follows:

ALL OTHER PACK AGES IV-3
Q k/
Full size graphic reproductions are shown for all labels and marks discussed in this manual. The Warehouse part number for the item is indicated in each graphie.
DOT LABELS These labels are commonly referred to as DOT labels or YELLOW H and YELLOW HI labels. All Schlumberger source packages require either the YELLOW H or YELLOW HI label.
There must be two DOT labels per package - one label each on two opposing sides. DOT labels should be accurately cen:pleted, as follows:
Contents - indicate the isotope (radionuclide)
Activity -indicate the number of curies j
Transport index - indicate the transport index of the pael: age.
The appropriate DOT label must be used. The YELLOW H or YELLOW HI label must accurately represent the contents of the package.

l l
l IIAZARDOUS MATERIALS SillPPING PAPER (DOCUMENT NUMBER SWS-2954)
A IIAZARDOUS MATERIALS SIIIPPING PAPER is required each time a radioactive source is transported on a Schlumberger vehicle.
For each trip, the paper must document all source packages that are aboard, and must be retained in the transporting vehicle, as follows:
1The legal term " shipping documents" refers to both shipping and transport as these
/]
terms are defined within this manual.
2 The word " shipping" as it is used in this document means " transport" as it is defiaed in this manual.
IV-10
q When the transporting vehicle driver is in the driver's seat, the HAZARDOUS J
MATERIALS SHIPPING PAPER must be within the driver's reach.
When the transporting vehicle driver is not in the driver's seat, the HAZARDOUS MATERIAIE SHIPPING PAPER must be in the pocket which is mounted on the inside of the driver's side door.
The paper must also be made available to the vessel operator when a source package is being transported offshore.
A pocket is installed on the driver's side door in all Schlumberger transporting trucks. It is suggested that this paper be retained in this pocket at all times during transport. A copy must also be retained in the District files.
BILL OF LADING (DOCUMENT NUMBER SWS-1656-B)3 A BILL OF LADING must be submitted to the common carrier each time a source package is shipped.
O A copy of the Bill of Lading must be retained in the consignor's fi'es.
Placards and Signs Each Schlumberger truck that is transporting radioactive material within a compartment must display the CAUTION - RADIOACTIVE MATERIAL - KEEP THREE FEET AWAY sign on the storage compartment doors. This sign is shown in figure IV-10. (The sign in the figure is reduced.)
Each Schlumberger truck that is transporting radioactive sources must display the 15" x 15" DOT RADIOACTIVE placards. Four RADIOACTIVE placards are required for each vehicle - one each o:1 the front, rear, and sides. This placard is shown in figure IV-11.
(The placard in the figure is reduced.) This placard must be removed or reversed when no radioactive material is being transported.

v STORAGE OF RADIOACTIVE MATERIAL The Nuclear Regulatory Commission (NRC) and state licensing agencies control the storage of radioactive material. When not in use or transport, all radioactive material must be kept in storage facilities that meet specific regulations.
Before the specific regulations can be discussed, two terms must be defined: " restricted access area" and " unrestricted access area". Schlumberger uses the following criteria in designating " restricted" and " unrestricted" storage areas:
A District storage facility is considered to be in a
" restricted access" area if it is:
- 1) located on the inside of a permanent-structure building, but at least one room removed from p
the administrative offices that are accessible to visitors, or
- 2) located outside of a permanent-structure building, but surrounded by a special fence with a locking system.
This fence must remain locked at all times, except when personnel need immediate access to the area.
A District storage facility is considered to be in an
" unrestricted access" area if it does not meet the qualifications listed above; in other words, when it is located outside of a permanent-structure building without a special fence and locking system surrounding it.
l These definitions ntust be used in determining access area designations at all Schlumberger District locations.
These definitions are applicable to tric following V
discussion of the regulations governing the design and use of storage facilities.
V-1 l
t
STORAGE OF LOGGING SOURCES Logging Source Packages All logging sources must be stored as a source package. Tnis term was defined in Section IVfor the transportation of sources. The definition also applies to the storage of logging sources; logging sources must be stored in their pressure vessel and carrying shield.
Storage Facilities Requirements for Storage Pit Design Logging source packages must be stored in a pit that is designed to meet the following standards:
- 1) The pit must be at least four (4) feet deep.
- 2) The pit must be dry.
- 3) The pit must be separated from all explosives pits by a minimum of four (4) feet O
er e rta er ee#erete-
- 4) The pit must provide shielding such that:
In an unrestricted access area, the radiation level on the surface of the storage pit does not exceed 0.6 mrem per hour.
In a restricted access area, the radiation level on the surface of the storage pit does not exceed 2.0 mrem per hour, and the radiation level at the perimeter of the restricted area must not exceed 0.6 mrem per hour.
5)
The pit lid must be equipped with a lock, and must remain locked except when pit access is required.
Any number of source packages can be stored in a single pit, any number ei pits can be used - as long as each pit meets these five requirements.
O V-2
O STORAGE OF CALIBRATION SOURCES AND PIP TAGS v
Calibration sources are not required to be stored as source packages. Ilowever, most Districts choose to store calibration sources as a package, inside the jig or carrying case.
Storage Facilities Calibration source packages and PIP tags have low radiation levels, and can be kept in a storage cabinet, provided the cabinet meets the following requirements:
- 1) The cabinet is dry.
- 2) The radiation level on the surface of the cabinet will be as follows:
In an unrestricted access area, the radiation level on the surface of the cabinet does not exceed 0.6 mrem per hour, n
In a restricted access area, the radiation level on the surface of the cabinet f
?
'v' does not exceed 2.0 mrem per hour.
- 3) The cabinet will be equipped with a lock, and will remain locked except when access to the cabinet is required.
For convenience, calibration sources and PIP tags may be kept in storage pits if desired.
STORAGE OF TRACER MATERIAL Storage of New Tracer Material New tracer material is received from the supplier in appropriate packaging. It must be stored in this package. Tracer material packages must be kept in souice storage pits or cabinets. The radioactive strength of the tracer material must be considered, and the required surface radiation level of the pit or cabinet must be maintained.
Storage of Radioactive Waste Resulting from Tracer Jobs Radioactive waste must be stored in a leak-proof container. This container must be C'
labeled with a CAUTION - RADIOACTIVE MATERIALS label (B-13042).
V-3
The waste container must be kept in a source storage pit or cabinet. The leak-proof container should be protected from damage. The strength of the radioactive waste must be considered, and the required surface radiation level of the pit or cabinet must be maintained.
SIGNS RADIATION AREA sign (s) - order number B-13388 - must identify all radioactive storage facilities, both pits and cabinets. The sign must be posted on both indoor and outdoor facilities. Figure V-1 shows a RADIATION AREA sign.

WIPE TESTING RADIOACTIVE SOUROES t
The NRC and each agreement state requires a manufacturer to decontaminate a source to the level of 0.005 microcuries or less. The NRC and each agreement state require a licensed user to report any removable activity in excess of this 0.005 microcurie level.
Schlumberger, as a licensed user, must:
Wipe test each radioactive source at least once every six months Submit the wipe test for assay Maintain wipe test assay cards Impound and report any source that is assayed over this 0.005 microcurie level, and provide for proper disposal of the source if necessary.
O)
v' Each District is responsible for wipe testing its sources and maintaining wipe test records. The District will be informed by the Radiation Safety Officer any time a source must be impounded.
WIPE TEST KITS Wipe test kits are available from the Schlumberger Warehouse, part number C-11594.
Each l<it includes:
1 one piece of filter paper in : glassine envelope l
one metal-lined bag with data card attached 1
one pre-addressed mailing envelope.
All wipe tests must be made using wipe test kit C-11594. There is one exception:
p/
emergency wipe tests (one made following an accident or because leakage is suspected).
i l
Emergency wipe tests must be accompanied by a note declaring the emergency.

V WIPE TEST PROCEDURES 1
A wipe test must be performed on each sourca once every six months. It is the responsibility of the District Manager to ensure that wipe tests are performed on schedule. The Unit provides each District with current wipe test status information on the RADIATION SOURCES CONTROL listing.
The District is provided with step-by-step wipe test instructions for each type of source. These instructions specify what tools to use, how to access the source, and where to wipe.
Differences in these instructions are due tt differences in the construction of each type of source and source housing.
ASSAY OF RADIOACTIVE SOURCES Wipe tests are sent to a licensed facility for assay. The results are reported to Schlumberger. If the scurce is assayed over 0.005 microcuries, the following stere are p
taken:
V The Radiation Safety Officer notifies the District to impound the source.
The Radiation 0;fety Ofter notifies the NRC or state licensing agency.
t WIPE TEST RECORDS j
Each District must retain all wipe test cards en file and available for inspection. The RADIATION SOURCES CONTROL listing may not be satisfactory documentation in some states.
1 p
Schlumberger rules say that a wipe should be performed on each source once every five d
months. This rule provides a safety margin in the event a source is in the field on the due date.

o FISHING / ABANDONMENT U
OF RADIOACTIVE MATERIAL Whea a radioactive toti ' ecomes stuck in a wellhore, the client is responsible tor all v
fishing and abandonment decisions. Schlumberger is responsible for advising the client, and reporting to the radiation licensing agency when nece:ssery.
When a radioactive tool is stuck, the Schlumberger District shall assist the client by providing the following:
1)
Information about the source and the tool (type and amount c4 radioactive material, tool dimensions, etc.)
2)
Mvice and recommendations on the most effective fishing operations.
2)
Monitoring of mud retut ns at all times during critical fishing operations.
V) 4)
Advice and recommendations on radiation satety for all rig personnel when the recovered source is brought uphole.
The District must report to Schlumbergcr manageme.it (as outlined in section XIII of this manual) when any one of the following situations arise:
1)
The client initiates a fishing operation contrary to Schlumberger's advice.
2)
The client refuses to initiate an advised fishing operation.
i l
l 3)
The source is stuck in an open hole and the cable or weak p$ int has been l
broken.
4)
The source is stuck in an open cable tool hole.
5)
The source capsule is in danger of being damaged.
O V
6)
The source is not recovered in the first fishing attempt.
VII-1 m
O)
U 7)
Abandonment of the source seems imminent.
8)
Mud returns show an incresce in rMioactivity.
Each Unit Safety Engineer mair.ains contact with the Radiation Safety' Officer in llouston. The P.rdiation Safety Officer is respon3iale for ensuring that Schlumberger's l
licensing agency is contacted when any situation is judged potential 4y hazardous. When appropriate, the Radiation Safety Officer also subn it' the client's abandonment proposal to the licensing agency.
Schlumberger's responsibility is to ensure that the source is recovered if practicable, or abandoned in such a way as to best protect people and property in the future.
SOURCE FISHING PROCEDURES Responsibilities of the Schlumberger Representative n
i i
'u/
ADVICE AND INFORMATION Schlumberger neither initiates nor performs fishing operations.
However, District personnel shall consult with the client during fishing operations.
A Schlumberger representative remains in contact with the client, to provide information about the source and tool, make recommendations, and monitor each phase of the fishing operations.
This Schlumberger representative is usually the Field Engineer, working under the guidance of the District Manager, tire Unit Safety Engineer, or tha Radiation Safety Officer. Responsibilities and reporting procedures wHhin this organization are defined at the Unit level.
When a radioactive source is stuck, the representative suggests to the client the course of action that Schlumberger judges to be the most effective means of safely recovering the source. If, at any time, the client refuses to act according to Schlumberger's advice,
('O 1
j Schlumberger's licensing agency for radioactive materials is the NRC in non-agreement states, and the responsible state agency in agreement states.
Vil-2
the representative will ask the client to sign a SPECIAL REQUEST FORM (document number SWS 685)2 This form must be retained in the District Office.
MONITORING OF MUD RETURNS Schlumberger must continuously monitor the mud returns during critical fishing operations - i.e., whenever the fishing tool is in the vicinity of the source. A gamma ray logging tool, when placed so that the mud returns flow over it, makes an excellent 2
monitoring device.
Any time the mud shows an increase in radioactivity, the Schlumberger representative must request that the fishing operation be halted, and immediately begin the reporting procedures outlined in Section XIll of this manual.
RETRIEVAL OF THE SOURCE The Schlumberger representative must always be concerned with minimizing the radiation exposure received by all personnel. From the time a retrieved source is brought uphole until it is returned to its shield, personnel exposure should be controlled, and the Schlumberger representative must follow the procedures listed below. These procedures are designed to keep personnel radiation exposure to a minimum.
The A
Schlumberger representative will explain these procedures to rig personnel, and make
+
every reasonable attempt to ensure that they are followed.
Before the last joint is started out, the Schlumberger representative must ask all non-essential persons to leave the rig floor. The only persons that should remain on the rig floor are: the Schlumberger representative, the driller, and enough rig personnel to cover the hole.3 The Schlumberger representative and remaining rig personnel should stand clear of the rig floor as the driller pulls the source as high as practical above the floor.
The rig crew should then cover the hole.
All personnel involved in the fishing operation should gather in a safe area for a planning conference.
- O 2The document number for Schlumberger Offshore Special Request Form is SOS 1599.
3 Rig equipment must be handled only by the client or contractor personnel.
VII-3
~
4 The Schlumberger representative should assess the situation and determine the best procedure for reshielding the source, and the minimum number of people s
required to assist. The Schlumberger representative must explain the procedure so that each person involved should understand exactly what to do.
The Senlumberger representative should place the shield near the spot where the source is to be released from the logging tool. The driller will return to the derrick floor to lower the tool, allowing the source to be removed from the tool and/or the logging tool to oe laid down with the fishing tool.
~
Usually, fishing operations proceed in a routine manner and the source is successfully retrieved.
Ilowever, there may be instances in which fishing is unsuccessful or an attempt is deemed unsafe. In such cases, the source may have to be abandoned in the well.
ABANDONMENT OF A SOURCE When abandonment of a radioactive source seems imminent, any responsibility to the state agency that issued the drilling permit remains with the client. It is the client's
. responsibility to prepare an abandonment proposal. It is Schlumberger's responsibility to submit the client's proposal to the NRC or state licensing agency for approval. It is then the client's responsibility to implement the proposal.
i The client's abandonment proposal will normally include:
1.
A hydraulic seal (normally a cement plug).
2.
Mechanical protection of the source from damage due to further attempts at drilling or deepening (normally a whipstock shoe or other deflection device above the cement plug).
3.
A plaque at the well head stating the presence of the source in the hole and a warning to avoid mechanical damage to the source.
(The plaque is normally engraved stainless steel, provided by Schlumberger and installed by the client) 4A Schlumberger source must be handled only by a Schlumberger Engineer.

,kJ PERSONNEL EXPOSURE NRC AND STATE REGULATIONS The NRC and state licensing agencies have established the maximum radiation doses that an individual can receive. The permissible occupational radiation dose per calendar quarter for a person over 18 years of age is:
Whole body; head and trunk; active blood forming organs; lens of eyes; gonads...........................
1,250 millirems llands and forearms; feet and ankles............................... 18,75 0 millirems Skin of whole body............................
7,500 millirems Schlumberger measutes employee exposure according to whole body rate. This 1,230 millirems may be taken in any combination, provided the calendar quarter dose rate does OQ not exceed 1,250 millirems.
An individual's exposure level may not exceed 5000 millirems per year for each year over the age of 18. Within these limits, an individual may receive up to 3000 millirems in any one calendar quarter, if documentation of lifetime exposure is on file.
I PERSONNEL MONITORING Radiation Badges Continuous monitoring with a radiation badge is required fo" any individual likely to receive a dose in excess of 25% of the regulatory limit. At a Schlumberger District, all Field Engineers, Operators, and Technicians are required to wear radiation monitoring badges. Other District employees may also require a radiation badge, depending on the nature of the job duties. The District Manager must make this determination. However, any Schlumberger District employee may request permission to wear a radiation badge, and this request will always be granted.
1The NRC has established separate guidelines for prenatal exposure. These guidelines will be discussed separately in this section.
Vill-1
Radiation Exposure Reports L
In the U.S., radiation badges are provided and read by a personnel monitoring service, and the results are printed as an OCCUPATIONAL EXPOSURE REPORT. This report shows whole body neutron and gemma exposure rates.
The OCCUPATIONAL EXPOSURE REPORT is approved for use as a record of personnel exposure in lie'> of forms required by the NRC and state licensing agencies.. Copies of the report are sent to the Radiation Safety Officer in flouston, the Unit Safety Engineer and the District Office.
OCCUPATIONAL EXPOSURE REPORT Records All OCCUPATIONAL EXPOSURE REPORTS - for both past and present employees -
must be retained in the files. If requested during an inspection, most inspectors will allow older EXPOSURE REPORTS to be destroyed.
Permission must be granted in writing, and signed by the inspector. If the request is not made, or if permission is denied, then EXPOSURE REPGRTS muri be retained indefinitely.
Monitoring OCCUPATIONAL EXPOSURE REPORTS Each District Manager is responsible for moaitoring the OCCUPATIONAL EXPOSURE n
REPORTS for all District employees, and taking the appropriate corrective action when b
necessary.
REPORTS BETWEEN 600 AND 1250 MREMS PER QUARTER Although the regulatory limit is 1,250 mrems per quarter, this is higher than the exposure rate normally received by Schlumberger field employees. A Schlumberger field employee r
is a " radiation worker" only in tile technical sense, and should not need to be concerned with radiation dosage received during routine operations.
Internal Schlum5erger rules require the District Manager to conduct an investigation if any badge is reported to have received radiation exposure in excess of 600 mrems per quarter. Results of the investigation must be made in written form, and sent to the Unit Safety Engineer and to the Radiation ScNty Officer in Houston. The investigative report must include:
The recson for the high exposure Action taken to prevent a reoccurrence of the exposure O
v VIII-2 s
REPORTS BETWEEN 1250 AND 3000 MREMS PER QUARTER d
If a badge receives between 1250 and 3000 mrems per quarter, the Radiation Safety Officer in Houston will contact the District Manager immediately. The District Maneger must submit a written investigative report as described above. The report must be submitted t0 the Unit Safety Engineer and the Radiation Safety Officer within 30 days.
The Radiation Safety Officer will take whatever action is necessary to ensure that the employee's allowable lifetime exposure is not exceeded.
REPORTS OVER 3000 MREMS PER QUARTER If a badge receives over 3000 mrems per quarter, the Radiation Safety Officer in Ifouston will contact the District Manager immediately. The same investigative report as described above is required. (The Radiation Safety Officer must submit a verbal and written report to the appropriate regulatory agency.) The Radiation Safety Officer will take whatever action is necessary to ensure that the employee's allowabla lifetime exposure is not exceeded.
GUIDELINES FOR PRENATAL EXPOSURE The NRC recommends that prenatal exposure should not exceed 0.5 rem (500 mrem) for the entire gestation period. Schlumberger assumes the responsibility for informing all female employees of this recommendation, and explaining the guidelines such that the employee understands the risks involved as they relate to her job.
The District Manager must provide this special presentation to each female employee in the District. New female emp!oyees should receive the presentation before working in a radiation area. Each presentation must:
Provide the employee with an exact duplicate copy of Regulatory Guide 8.13.
Provide the employee with an oral explanation of the NRC conclusions and recommendations concerning prenatal exposure and how these conclusions relate specifically to her job.
Provide the employee with an opportunity to aax questions.

INCIDENT REPORTING Each field location is responsible for reporting potentially hazardous incidents involving the use of radioactive materials.
WHAT TO REPORT The District must report when any of the following situations occur:
1.
Report any of these conditions regarding a stuck source:
The cable is stuck in an open cable tool hole and the tool / source is still atteched.
The source is stuck in an open hole and the cable or weak point has been broken.
1 The client initiates a fishing operation contrary to Schlumberger's advice, or refuses to initiate an advised fishing operation.
O The source is not recovered in the first fishing attempt.
Mud returns monitored during a fishing operation show an increase in radioativity.
The source capsule is in danger of being damaged.
Abandonment of the source seems imminent.
2.
Report any suspected everexposure of personnel to radiation. For titis purpose, overexposure means any exposure in excess of that normal)y expected in the performance of routine work, not necessarily exceeding regulatory limits.
3.
Report any interest by the media in our activities involving radiation.
O IX-1

4.
Report immediately if a source is last or stolen. This is urgent, since it presents a O
potential hazard to the general public.
5.
Report immediately if the source cannot be retrieved from the tool and replaced in the shield.

O EMERGENG
Y. PROCEDURE
S The following procedures nave been established in case of a serious accident involving radioactive material. An emergency of this magnitude involving a Schlumberger source is unlikely. liowever, all Field Engineers must know these procedures, and be prepared to initiate them in case of an emergency.
Notify the Unit Safety Engineer as soon as possible. The evaluation of an accident inay require special instruments that m:nt to brought in pro :ptly.
1.
If an accident involves a person trapped within an exposure area, the Field Engineer must judge the situation, and take the appropriate rescue action. Rescue is the primary concern, but the Engineer must take all practical precautions to minimize exposure to other personnel If possible, radiation exposus should be spread amcr.g a large rescue crew for short periods rather than allowing one person to receive high exposure.
2.
Restrict any area which might be contamineted. Keep the public away.
3.
Segregate and retain all persons who may have been exposed. Retain the names of all persons who may have been exposed. If there is a possibility that clothing or skin rtay have been contaminated, have the persons shower and change clothes as quickly as possible.
4.
Remove any injured person to a transfer point away from the contaminated area.
Be sure the attending physician Imows that radicactive contamination might be involved in the accident.
5.
In fighting a fire, treat the fumes as toxic material, and fight from the upwind side.
All suspected material should be carefully monitored for radioactive contamination before being returned to normal service.
6.
If a vehicle is involved in an accident, evaluate the extent of a possible release of radioactite material as promptly as possible, while routing traffic around the area gb that may be contaminated. Keep the public away.

oU STATE REGULATIONS COMPLIANCE WITH STATE REGULATIONS Each district must be familiar with the regulations of all rtates within its operating region.
Schlumberger must comply with the regulations of the state in which a radioactive source is being used. Schlumberger must also comply with the transportation regulations of the state through which a radioactive source is be.ing transported.
STATE Ll;pENSES Each Schlumberger District must retain a copy of the license for all states in which it operates.
These licenses must eithe be conspicuously posted or kept availabh* for inspection upon request. Because a license with amendments is lengthy and bulky, it i.s standard procedure et the Districts to have a copy of each license available upon request.
All Schlumberger state license numbers are listed in the chart on page XI-3.
RECIPROCITY Districts may be called to perfor m services in an agreement state for which Schlumberger is not licensed.
Each agreement state has regulations for reciprocal recognitions of licenses.
The District must contact the Unit Safety Er.gineer to determine what course of action is necessary to comply with the regulations of that particular agreement state.
STATE ' NOTICE TO EMPLOYEES" FORM The proper NOTICE TO EMPLOYEES must be posted at each District office. For land Districts storing radioactive materials in an agreement state, the District must post the state NOTICE TO EMPLOYEES in the District office.
For land Districts storing radioactive materials in a non-agreement state, and for all offshore Districts regardless n
of location, the District must post the NRC NOTICE TO EMPLOYEES and the state NOTICE TO EMPLOYEES, if any.

nU SCHLUMBERGER OPERATING RULES Since Schlumberger began using radioactive materials in 1950, radiation safety - the protection of pcAunnel and property - has been a fundamental company concern.
Because of this concern, Schlumberger enforces a set of internal safety rules that are not addressed by federal or state regulatory agencies. These rules, listed below, apply specifically to well logging operations.
1.
The locked radioactive source shield must be chained and locked to an integral part of the truck or pallet during transport. The Engineer and each Operator in the truck are responsible for ensuring that this rule is followed.
2.
A radioactive sxrce must be locked in its shield when not in use. It must not be unchained from the truck until it is needed at the well, and must be immediately rechained and locked to the truck after the operation. The Engineer and each operator at the wellsite are responsible for ensuring that p
this rule is followed.
U 3.
The hole must be covered when a logging source on the rig floor is being transferred between the tool and shield. The Engineer and each Operator on the rig floor are responsible for ensuring that this rule ;s followed.
4.
The Engineer must personally transfer the radioactive logging source, using the remote handling tool. This operation must not be performed by any other personnN. The Eig!ncer is responsible for ensuring that this rule is followed.
Each operator is responsible for knowing that he/she is not authorized to perform this operation.
C.
The loss of any source or other radioactive material, or any suspected overexposure, must be reported immediately to the Unit Safety Engineer.
The Engineer is responsible for ensuring that this rule is followed.
The preceeding rules must be followed without exception by all operating crew personnel.
V X11-1
. _ _ _ = _
An additional set of rules must be followed by Schlumberger crews performing tracer jobs. These rules are:
1.
Before and after each tracar job, the area must be surveyed with a Ludlum II or equivalent instrument. The Engineer is responsible for ensuring that this survey is made.
2.
Eating, drinking, and smoking'is prohibited while handling tracer material.
Eating, drinking, and smoking is also prohibited after the tracer job, until the "after-survey" has been conducted. Each crew member is responsible for following this rule.
3 The Engineer must personally transfer the tracer material. The Engineer is responsible for ensuring that this' rule is followed, and each operator is responsible for knowing that he/she is not authorized to perform this operation.
4.
Tracer material must be transferred over an absorbent material with a liquid-proof barrier. The Engineer is responsible for ensuring that this rule is followed.
5.
The Engineer must wear plastic gloves while transferring tracer material.
6.
Personnel other than Schlumberger employees must be kept away from the area while tracer material is being transferred until the area has been surveyed " clean". All non-essential personnel should remain in a radiation field of less than 2 mrem per hour. The Engineer is responsible for ensuring that this rule is followed.
J Schlumberger provides its field employees with the best sources and shields obtainable, and provides radiation safety training to Field Engineers respensible for supervising the use of radioactive logging equipment.
Schlumberger takes pride in the success of its rudiation safety efforts. Incident rates are extremely low. When an incident does occur, immediate steps are taken to make any
]
equipment or procedures modifications necessary to prevent the incident from happening again.
