1 WL-QHSE-S03-WC / Statement of Standard 1

1 Statement of StandardWinch control, Winch, S011, s0011, s011, QHSE, IPC

Winch operations involving a wireline cable and winch unit are part of virtuallyevery job performed across Wireline. These operations present a significant riskto Schlumberger personnel and equipment and are seen by Schlumberger clientsas an integral part of quality service delivery. Therefore, all winch operationsshall be conducted in a way that minimizes these risks to an acceptable level,through management of the required equipment and procedures, qualificationof the involved personnel, and appropriate Hazard Analysis and Risk Controlperformed as specified in OFS QHSE Standard 020.

2 ObjectiveThe purpose of this Standard is to define minimum requirements for all operationsin which a wireline cable and winch unit are used. These requirements enableSchlumberger to minimize the associated risk to both personnel and equipment,while also providing the client quality service delivery. Any non-compliancewith this Standard requires an approved exemption as outlined in theManagement of Change and Exemption Standard – Wireline appendix.

3 ScopeAll cable/winch operations conducted across Wireline, including those involvingcontractors and contractors’ equipment, shall comply with this Standard and withapplicable client requirements, whichever are the highest.

All winch operations shall be supervised directly by the engineer or specialistin charge. This is true even if the lead operator of the field crew has moreexperience than the engineer or if the client is inside the logging unit. Theengineer is ultimately responsible for the operation.

Listed below are some specific responsibilities for wellsite personnel.

• Engineer or Specialist in Charge

– Ensure that the right crew members are in the right place when the toolis near the surface. This includes matching tasks with appropriate skillsand ensuring that people are in proper position prior to moving thewinch. When considering assignments, the engineer shall ensure thatthe winch operator is 100 percent capable of safely operating the winch.Be especially aware whether there is an adequate amount of rest andalertness (24-hour lifestyle).

– Select weakpoint and manage the cable speed during the operation.

– Enter the correct WFDD depth and tension parameters. This includesthe IDW/CMTD calibration values and the depth/tension alarms andshutdown ranges.

– Calculate and display the maximum safe pull (MSP) in the winch area.

– Remove distractions from the operation. The use of cell phones is strictlybanned during the operations of the winch.

It is essential for the engineer to prioritize and manage the operational tasks.This means the engineer must stop other tasks at hand (such as playbacks)when the tool nears the surface. If the engineer cannot stop these tasks, stopthe winch until full control is possible.

• Crew

– The winch operator shall be proficient with controls, indicators, standardsand emergency procedures for the particular unit being used.

– Before beginning the job, the winch operator shall take time to becomefamiliar with the cable position on the drum at tool zero and all valueson the WFDD.

– If a change in winch operators is necessary, the relief winch operatorshall be fully briefed. Be sure to review any changes in measured vs.driller depths, any tight or problematic spots, and current winch settingsincluding normal tension, cable speed, and maximum safe pull specifiedby the engineer.

– The crew must understand that operations within 300 ft of the surfacerequire the operator’s undivided attention. Any “in cab” distractionsshould be eliminated before proceeding with winch operations.

– The operator should review the basic winch hand signals to ensurestandard hand signals are being used. (Section 5.7)

4.3 Reporting and InvestigationReporting, investigation and review of CMSLN incidents related to winch controlshall follow the QHSE Event Reporting and Management (HSE) Standard(SLB-QHSE-S002-HSE), most specifically its appendix for Wireline operations.

In the case of UPO or other winch control-related CMS, the field engineer isresponsible for capturing all the details required for complete analysis of theincident. Information such as WFDD logs, sequence of events, well data, logs,equipment, etc. shall be captured at the time of the incident and sent immediatelyto the location manager. The location manager is ultimately responsible foraccurate and timely reporting of these incidents. The manager shall also guidethe investigation and analysis process, including review of the location analysiswith InTouch.

4.4 ProceduresOperating procedures specific to each piece of equipment required in winchoperations can be found in the operations manuals for the specific equipment.(Refer to Section 6.2.1 – InTouch Reference Pages for winch control equipment.)

4.4.1 Safe Winch Operations PlacardThe official WLH Safe Winch Operations Placard shall be posted in all wirelinelogging units. The latest version of this placard shall be displayed in view of thewinch operator in addition to any required local language translations. Each crewmember shall be familiar with the procedures listed on the placard. The mostcurrent version of the placard is located in InTouch Content ID # 3885138. (Referto Section 5.6 – Safe Winch Operations placard). See Figure 5-3.

4.4.2 Alarms and ShutdownsThe WFDD (and/or WCC or SWCT) is the depth/winch control and monitoringsystem used in wireline logging units. Alarms and shutdowns are used onboth the tension and depth systems to help safely control the operation withinpredefined safe operating ranges. Engineers must verify the systems arefunctional.

• The alarm is both visual and audible, warning that the operator is approachinga predefined operating limit.

• The shutdown also gives both a visual and an audible warning, butautomatically stops the winch and prevents operation beyond the predefinedlimit.

The engineer/specialist in charge shall enter correct depth and tensionparameters into the winch control system. This includes the updated IDW/CMTDcalibrations and appropriate depth/tension alarms and shutdown ranges.

Potential Severity: MajorPotential Loss: Assets, ProcessHazard Category: Machinery equipment hand tools

Alarms and shutdown systems provide back-up protection but may be slow toengage and do not operate in a fail-safe manner. They must be functionallytested on a each job. When approaching surface these systems must not berelied upon to stop the winch in time to prevent a pull-off. Speed control is theoperator’s best protection against pull-off. Speed too fast for conditions is aleading cause of unplanned pull-offs.

4.4.3 Winch Speed GuidelinesMany factors need to be considered to decide on an appropriate winch speedfor a given operation. In general, the difference in normal tension compared tostatic tension provides the most valuable information.

If the tool depth is less than 100 m (300 ft), the cable speed has to be less than2,000 ft/hr. However, if the need arises, the speed can be increased up to 6,000ft/hr for subsequent runs during a continuous operation, between 100 m (300ft) and a depth equal to the length of the toolstring or 15 m (50 ft), whicheveris deeper. Remember that cable stretch and reaction times will be less whenoperating at shallow depths.

Note that in the following cases, the 2,000 ft/hr limit remains: rig-up/downoperations; caliper or other device in the OPEN position; pressure jobs wheretool trap and head catcher are not available; descents with misrun; potential splitgun; and when the status of the toolstring or depth control systems is in doubt.

When the logging toolstring is about to pass through difficult sections inside awell (such as line-hangers, sub-sea BOP (blow out prevention), surface BOP,etc.), this should be considered when deciding the winch speed to prevent anunintentional pull-off or stuck depth.

Recommended Wireline Cable Speed Guidelines for “Normal Operating”Conditions are maintained by IPC in Chapter 7 of the Armored Logging CableOperating Manual (InTouch # 3614996).

Refer to the sections Recommended Cable Speed Guidelines Placard and 5.1,Recommended Cable Speed Guideline.

4.4.4 Weakpoint and Maximum Safe PullThe general rule is to use the strongest-rated weakpoint available that will stillpermit pulling off a stuck tool at total depth without exceeding the safe workingload of the cable or logging unit. The weakpoint must also be able to carry theweight of the toolstring under normal logging operations. In some extreme cases,an ECRD or ERS (Electrically Controlled Release Device) should be consideredin place of a standard mechanical weakpoint.

Refer to the Tension model in the Schlumberger Tool Planner when choosinga weakpoint; this is essential for non-vertical wells (DCS InTouch case ID#3272999). The engineer and winch operator need to know the maximum safeoverpull value (MSOP) and the maximum safe pull (MSP) at all times. The

maximum pull on the weakpoint should not exceed 75% of the lower weakpointrating downgraded with temperature (LWPR). Therefore, the maximum pull atsurface should not be bigger than 75% LWPR + force needed to pick up cableweight in mud and overcome friction force plus fluid drag on the cable:

MSP = 75% LWPR + Wcm + Fc + Dc (with MSP the maximum safe pull, Fc the friction onthe cable and Dc the fluid drag on the cable)

The normal tension measured at surface includes:

TN = Wcm + Fc + Dc + Wtm + Ft + Dt (with TN the normal tension, Ft the friction onthe tool and Dt the fluid drag on the tool)

Properly calibrated head tension measured downhole includes:

Thead = Wtm + Ft + Dt ( with Thead the head tension measured by downhole sensor)

Thus:

MSP = 75% LWPR + TN - Thead

For any situation where a valid and calibrated head tension is not available, TheWtm will provide with the next best value to estimate the MSP but in this casemeasuring TN at a speed as low as possible. Notice that using Wtm insteadwill actually overestimate MSP.

• Double check the TN used to calculate MSP and compare to estimated value.

Investigate, understand and explain differences in values.

• Always use the LWPR value corrected for downhole temperature (See HeadsManual IT#: 3012542). Always remember that the strength of the weakpointis a function of temperature.

• The MSP shall also not exceed 50% of the fixed ends breaking strengthof a good cable.

Quality NoteNote that a good cable is defined as one meeting the requirements of the armorlogging cable ductility test.

• The maximum safe pull shall also not exceed the logging unit maximum loadratings. In any case where it is expected that the logging surface tensionmaximum safe pull will exceed 8,000 lbf, the Wireline High Tension Standard(WL-QHSE-S11-HT) must be followed.

Potential Severity: SeriousPotential Loss: PersonnelHazard Category: Electrical

Blind reliance on electronic tool planners or spreadsheets is no substitute forunderstanding the math behind the calculations. Employees must be able todemonstrate a complete understanding of these principles prior to operatinga winch unit.

4.4.5 Secondary Depth ControlA properly calibrated IDW always provides the primary depth measurement.However, redundant depth systems should be employed to allow recovery incase one system fails. A minimum of three independent depth systems shouldbe used at all times.

The IDW provides two depth systems (wheels). When both are enabled,discrepancies (wheel slippage) are detected and automatically compensated forby the surface acquisition system. Ensure that both depth systems are enabled,functioning and accurate. Do NOT enable/disable while moving the winch.

The engineer and winch operator should use a third independent depth systemand notify each other if any discrepancy is found. Both are responsible formonitoring depth accuracy, stopping operations and resolving any depthdiscrepancy before proceeding. This double check is a team effort or “buddysystem” used to prevent unintended incidents and should be used both running“in” and pulling “out” of the well.

Examples of secondary depth control systems are:

• Z-Chart

• drum counter

• flagging.

At a minimum the Z-chart must be used.

4.4.6 Customer-Provided EquipmentBefore using equipment provided by the customer, Schlumberger personnelshould ensure that it conforms to this Standard.

4.4.7 Wellsite SetupIt is important to position the logging unit and equipment so that it provides thewinch operator with a clear line of sight for the entire operation. Because thisis not always possible, the crew shall determine a setup that allows for botha safe and efficient operation. Standard winch hand signals shall be used asshown in section 5.7.

In cases where no clear line of sight is available, risk mitigation proceduresshall be in place. Location Management should decide where to use or not useremote video devices for rig up/down and winch operations. Such equipment, ifused, shall be certified for the proper zone of operation.

The wellsite setup should be one of the first tasks undertaken upon arrival at thewellsite. A working communication system and predefined hand signals areessential between the winch operator and crew.

For land operations, the rig location is usually designed with a specific area at theend of the catwalk where the logging unit can be set. For proper and safe wellsitesetup, regardless of operating conditions, three main steps shall be followed:

1. Align the truck.

2. Anchor the truck with proper Wireline wheel chocks or backup legs withconsideration for both weather and surface conditions.

3. Apply the truck’s spring parking brakes.

Refer to WL - Standard Wellsite Setup for Wireline Logging Trucks InTouchcase ID: #4109800.

On offshore rigs the logging unit sometimes needs to be placed in the mostconvenient location for drilling operations, not for logging operations. Clearcooperation and coordination with the offshore rig representatives is fundamental.Refer to Wireline Oilfield Units Reference Page InTouch case ID: #3264711 forwellsite setup instructions in Offshore Units, Modular Units, and so on.

In cases where there is no typical setup and space is often at a premium (suchas cased hole operations with wellhead equipment, production equipment,equipment from other service companies, pressure control equipment, etc.), itis important to coordinate the setup to maximize the view of the wellhead areawhile also allowing for an efficient operation. Account for things such as accessfor rigging up tools and pressure equipment; a place to safely prepare anyexplosive services; a clear line from the winch unit to the wellhead; and so on. It

is usually very difficult to change the setup once the operation is started. Thecrew needs to make sure that the setup is correct from the start so that the safetyof people and equipment are not compromised in any way.

4.4.8 Winch Tension Limiting System (TLS)The TLS reduces the maximum hydraulic pressure that can be developed by thewinch system. The pressure, in turn, limits the maximum tension that can bedeveloped by the winch system. The tension limiter is not capable of allowingfree-wheel; however, when set at its minimum value, it permits the cable to bepulled from the drum by an external force (such as a shop winch or during TLCoperations). Nonetheless, if the TLS is adjusted to a pressure less than thatrequired to move the tools uphole, the tools will begin to drop. Increasing thelimiter settings will restore the pressure necessary to maintain control over thehanging load.

The TLS shall be used during the following operations:

• spooling cable in the shop

• TLC operations

• rig-up/rig-down

• POOH as an additional pull-off prevention method

• remote radio winch control operation.

All Schlumberger units need to have a working TLS. Specific instructions forusing the TLS on each system can be found in the specific logging manual andInTouch Best Practices. Refer to Units Manuals or the Wireline Oilfield UnitsReference Page InTouch case ID: #3264711 for instructions on how to use theTLS system on each type of logging unit.

NoteTLSs are not just for use during TLC operations. They are to be used with allWireline cable spooling operations.

4.4.9 Wellsite OperationsRunning In the Hole (RIH)

When the engineer is prepared and all systems are ready to go, the winch mancan proceed in the well. Be sure to take the following precautions:

1. Do NOT exceed cable speed guidelines.

2. Disable the TLS once the rig-up is finished.

3. Make sure the tension is increasing as you go into the well.

4. Adjust the Tension alarms regularly. Keep the lower alarm slightly below theobserved tension while running in the well.

Low tension alarm should be set to 0.67 (OH) or 0.8 (CH) times the statictension. An triggered tension alarm is indicative of speed too high for currentconditions.

Low tension shut down stops the which should the tool bridge and tool weightis lost. Set low tension shut down to 0.67 (OH) or 0.8 (CH) × [static tension -weight of tool in mud].

5. The engineer should monitor the down log to verify that the tools are moving.

6. Well conditions will determine the appropriate speed (for example, slow downin any tight zone, deviation kickoff point, or doglegs).

7. Use the Z-Chart to record the depth and tension at each flange break.

8. The winch operator should devote 100% attention to winch operation. It isnot appropriate to take on any other duties while operating the winch.

9. Visually monitor the physical setup (CMTD, IDW, sheaves, etc.) and ensurethat all control systems remain operational.

10. Use the TLS during TLC jobs while running in the hole with the drilling pipeafter the cable side entry sub (CSES) has been fully installed.

Downhole Operations/Logging

1. Refer to the Recommended Cable Speeds Guidelines placard (Figure 5-1)for general operations or follow the guidelines for the specific tools orservices that you are running.

2. Tension alarms/shutdowns should be set based on cable speedrecommendations and well conditions, but normally shutdown should beno grated that 500 lbs above normal tension (100 - 200 lbs for cased holeoperations). The winch alarms and shutdown settings require continualadjustment.

High tension alarm should be set to 1.3 (OH) or 1.2 (CH) times the statictension. A triggered tension alarm is indicative of speed too high for currentconditions.

Set the High tension shut down to about 500 lbs (OH) or 200 lbs (CH) aboveHTA. The winch alarms and shutdown settings require continual adjustment.Only if speed has been brought down, the HTS can be set to MSP (seesection ).

3. An alarm/shutdown should never be set above the MSP or 50% cablestrength or maximum tension limitations for the specific logging unit.

4. Continue to update the Z-Chart and cross-check depth systems.

5. Periodically check tension readings (especially prior to reaching TD) andcompare to expected values.

6. Do not stop in open hole for long periods if possible. Keep the cable movingto prevent differential sticking.

7. The TLS can be used to prevent an unintentional pull-off once the upholeoperation is begun (i.e., logging up has started).

8. Once again, verify system status and functionality.

Pulling Out Of the Hole (POOH)

• Once the downhole operation has been completed, the winch operatorand engineer should confirm that any calipers, probes, or assemblies inthe toolstring have been retracted prior to increasing the winch speedwhen starting to POOH. Follow the cable speed guidelines and regularlycross-check the depth against the IDW and cable position at the drumflanges (Z-chart).

• Monitor and adjust the tension shutdowns/alarms (and tension limiter) as youproceed out of the hole. Keep the values close to the normal cable tensionand below the maximum safe pull at the current depth. Remain alert forrestrictions, changes in the well profile, or other areas that require a reductionin cable speed.

The winch alarms and shutdown settings require continuous adjustment.

• Stop the winch between 100 m (300 ft) and 70 m (200 ft) from surface or seafloor when POOH and apply the brakes. The crew should use this time toreview the rig-down plan. The engineer should coordinate crew positioningand assign duties for winch operation, removal of the pack-off or line wiper,and the bump-up procedure inside the WHE, if applicable. Do not move thewinch until all explosives, radioactive, and wellhead equipment procedureshave been discussed and are understood.

• Make sure the TLS (shutdowns/alarms) is properly adjusted to prevent anunintentional pull at surface and during rig-down.

• It may be necessary for a different crew member to take over the winchoperations to bring the tool to surface. Be certain that the depth and tensionalarms are set properly for surface operations before releasing the brakesto start moving the winch. Keep the winch speed below 2,000 ft/hr or asdescribed in Winch Speed Guidelines, Section 4.4.3 of this Standard.

Recommendations for setting rig-up/down high tension alarms are as follows:

HTS = 50% LWPR (or 50% of cable SWL if using ECRD) + weight of tool in air

HTA = weight of tool in air, or 50% LWPR whichever is lower (or 50% of cable SWL ifusing ECRD)

TLS should be enabled.

Bypassing the shutdowns or alert systems is forbidden (except in rareemergency situations or in TLC operations).

Moving the cable up and down in stuck situations is discouraged. Followoperating guidelines for further details.

Guidelines for operating during a stuck tool condition are found in Appendix 5.2,and guidelines for bump-up procedures are found in Appendix 5.3.

The best way to estimate static tension is to use Tool Planner: (Tup + Tdown)/2.As a second option, the user can measure regular up and down tensions overthe same interval at a speed as low as possible, then estimate the static tensionas the average between tension up and down. In this case take the tensionmeasurements over a long interval (more than 15 ft of tool movement) andcheck that the tension is steady and correlates to well conditions, estimates,and previous measurements.

4.4.10 Logging Operations Under High TensionIn any logging job where the Tool Planner or other indicators suggest that thelogging surface tension maximum safe pull will exceed 8,000 lbf, the WirelineHigh Tension Standard (WL-QHSE-S11-HT) must be followed.

A HARC shall be prepared to identify and mitigate all risks associated withthese operations.

4.4.11 Winch Control During Fishing OperationsWireline Pipe Recovery and Fishing Operations need to have a special riskassessment (InTouch case #3297069) performed by the crew. Refer to theWireline Fishing Standard (WL-QHSE-S09-FISH) for specific details on theseoperations.

4.4.12 Winch Control During TLC OperationsWireline TLC Operations have special requirements and limitations. Refer to theTLCS-HA and TLCS-SA/AC Operations Reference Manuals for specific detailson these operations - (TLCS-HA - Intouch Content ID 3797385, section 5.3, andTLCS-SA/AC - Intouch Content ID 4220980, sections 6.3 and 6.4)

4.4.13 Shop WinchIt is essential to have a properly set up and equipped cable maintenance yard inorder to provide proper maintenance on wireline cable. Cable Maintenance ShopSet Up guidelines are available at InTouch case # 3291969.

Locations shall only use Cable Shop Spooling Units approved by Schlumberger.These units can be found at IPC – Wireline Logging Common Surface Equipmentweb site.

Inspections shall be carried according to Section 4.4.14 Inspections, Tests andMaintenance of this Standard.

A HARC analysis for the operation of any shop spooling system shall beprepared to identify and mitigate all associated risks. This includes cablespooling operations performed in conjunction with third-party companies.

If an exception is required, follow the guidelines provided at InTouch case #4118945.

4.4.14 Inspections, Tests and MaintenanceAll equipment required for the winch operation should be inspected at least onceper quarter. Also, it needs to be tested and maintained according to the specificequipment maintenance manuals and/or RITE File Code Catalog:

• The prescribed maintenance events are defined by the product centers.

• The maintenance is carried out by the location and shall be documented.

• InTouch provides the necessary technological support.

The winch control equipment requiring maintenance/inspection includes (but isnot limited to) the following:

• CMTD and IDW

• WDR (Cable Drum)

• Winch Drive (chain and sprocket)

• Winch Transmission (including base plate)

• Winch Brakes (properly adjusted)

• Unit (connection to rig or truck tire chocks).

In addition, all control systems must be functionally tested beforeconducting any job: depth, cable speed, cable tension, TLS, winch brakes,brake bands or pads adjusted, visible/audible alerts, and communicationssystems.

Inspections are a critical tool and detailed land and offshore winch unit inspectiontemplates can be obtained in the Wireline Operations Management System AuditPackage (InTouch case # 3281343). The focus of all inspections and audits is, ofcourse, the closure of the resulting action items to ensure compliance.

4.4.15 Performance MonitoringKey performance Indicators (KPIs) allow management to quantify and monitorcompliance with this Standard and performance at the location.

For winch control, the KPI is UPO per 10,000 jobs. The World Wide ServiceQuality Plan (WWQP) indicates that every GeoMarket should have in place aService Quality plan that includes a KPI target for UPOs.

Wireline Headquarters uses the KPI data along with details of UPO incidentreviews (shared through InTouch) to guide this Standard, set new WWQPobjectives, and as input into new winch control product design and development.

4.4.16 Training and QualificationTraining for winch operations should be completed through the PEPTEC, XPERT,or GlobalTOPS programs. Documentation of completed training is maintainedin the LMS.

5.1.2 Additional Operating ConsiderationsLower speeds and control of tension must be considered for wellbore equipmentand operating considerations. All tension readings, tool response and toolmovement must be monitored for the following:

• well conditions – over tight spots , restrictions, casing/tubular changes,packers, valves, etc., should limit winch speed to 3,000 ft/hr or less.

• deviated wells – ensure proper tool and cable movement by knowing andunderstanding expected minimum weights in fluid.

• tool types – 1) tool requirement - (pads, bow springs, packer elements,magnetic elements), and 2) alignment, clearance and fluid bypass

• cable types – when using new, unfamiliar cables (or sizes) especially alloycables, run more slowly and cautiously particularly when rapidly changingdirection or speed (i.e., see cable seasoning in ALC ORM, section 7.1).

• extended jobs or stationary measurement – when wellbore equipment oroperating conditions may have changed. In order to prevent the wirelinecable from becoming differentially stuck during a prolonged stationaryoperation (i.e., sampling), the wireline cable can be sporadically movedup/down, limiting tension differential to: 0.8 Ts < T < TN.

Cycling cable to avoid differential sticking during stationary measurementsmust be avoided during high tension operations. See the High TensionStandard, S11, Intouch #: 4677354, section 4.3.3.

• Setting and activating wireline jars

5.1.3 Consequences of Winch SpeedIt is important to understand that driving a winch at higher cable speeds,like driving a vehicle, requires skill (from training, practice and experience),concentration, good equipment, and knowledge of the road ahead. At the sametime it must be clear to everyone that speed always comes second to safety.

Going too fast can cause:

• unintentional pull-off

• stored torque (leading to a reduction in the life and rating of the cable)

• bird-caged cable due to insufficient tension during RIH

• knotted cable caused by running the cable past the tools downhole

• tool damage caused by spudding or excessive wear

• jumping sheave during sudden changes in tension

• loss of primary data while logging.

5.1.4 Consequences of Cable CyclingCycling the wireline logging cable in an attempt to get free has historicallyresulted in cable damage, lower weakpoint strength, unintentional pull offs andcable breakage.

Other specific cable damage that may go unnoticed and lead to reduction incable strength includes:

• loose / stranded armors

• bird cages

• kinks

• cable knots / looping

• conductor damage

• torque and load imbalances between armors.

Among others, the most critical factors influencing cycling effects are:

• wireline speed

• cable type

• cable condition

• number of cycles

• tension differential during cycling process

• borehole conditions.

Because of the multitude of variables involved, it is not possible to accuratelydefine or quantify a "cycle", predict the damage or presume an outcome.Therefore, avoid cycling the cable.

For additional details see also the “High Tension Effects on Cables” TBT atInTouch #: 4336063

5.2 Stuck Tool SituationWireline logging carries some inherent risks and the potential for the toolstringand/or cable to become stuck in the wellbore or production string. There is nofailure-proof method to prevent sticking or to free a stuck tool.

If the surface logging cable tension maximum safe pull is, or expected to be,greater then 8,000 lbf, Go to the High Tension Standard, High Tension Standard,WL-QHSE-S11-HT section 4.3 (Intouch Content ID: 4677354), OTHERWISEcontinue within this section.

Wireline cable must NOT be cycled in an attempt to free a stuck toolstring.

For operations using pressure control equipment, there is additional risk ofcable sticking in the WHE. These cased hole operations require heightenedsafety awareness and additional guidelines as described in the Stuck-CableOperating Procedure (SCOP). See InTouch Content # 2023536 Stuck CableOperating Procedure.

5.2.1 Stuck Situation ProcedureDuring the complete stuck tool procedure, wireline speed is to be the minimumspeed achievable with the winch.

1. Upon confirmation of being stuck pull maximum tension (MSP or cable SWLwhichever is lower) and set the brake.

Do not exceed the safe working load (SWL) of the wireline logging cable or75% of lower weak point rating at the head.

High Tension Shut Down must not be set to MSP value until the winch speedis reduced to the lowest achievable.

2. If the client is not aware of your situation, immediately inform the customerand explain your plan.

Alert to the rig crew that the wireline tools/cable are stuck so they are awareof the situation as well.

3. Continue to monitor the tension while the brake is set and close all calipers.

Be prepared to sit and monitor tension for at least an hour.

4. In the meantime re-affirm that the fishing kit is complete with required grapplesizes for fishing the stuck toolstring and the drillpipe thread sizes of subsrequired for your job. Inspection is performed at the shop or upon arrival.

5. Over a period of time (different for every situation), the tension may decreaseby 200 lbs to 300 lbs. If this occurs, pull back to maximum tension andre-apply the brakes. Doing this several times is not uncommon during thewait period.

6. If the tool remains stuck after the wait (usually a few hours), discuss toolretrieval options with the client and initiate the most appropriate method.

5.3 Bump-Up ProcedureThe bumping technique is used for surface operations when the toolstring is notvisible to the crew (i.e., inside the lubricator or approaching packoff). Bumping isa technique in which a crew member applies downward force on the cable alongthe rig-up length. The crew member will feel the toolstring “bump up” against thecatcher, top of the lubricator or packoff, and alert the winch operator to stop thewinch. The same technique is used when releasing the head from the catcher toprevent the toolstring from taking momentum, prior to RIH. Because some extraslack has been introduced into the rig-up length, there is extra reaction timebefore excess tension is applied at the head.

Bump up midway between the drum and the lower sheave. Do not allow all theslack to be removed from the cable. Cable slack is the essential component thatgives extra reaction time and prevents overpull on the weakpoint.

Holding down the lower sheave wheel rather than the cable is not arecommended method for bumping up. This technique should only be consideredif there is no other bump-up position available along the cable. A risk assessmentmust be completed to determine if this can even be done safely.

Reminder: Due to well head pressure, the tension at the weakpoint may notequal the tension displayed.

The following guidelines must be observed when applying the bumpingtechnique:

1. Prior to initiating rig-up or rig-down operations, hold a safety meeting todiscuss the operation (including bump-up) and assign crew duties.

2. One crew member should be positioned midway between the logging unitand the lower sheave wheel, while the other crew member should be nearthe wellhead.

3. Once in position, the crew member on the cable signals the winchman tostart coming up slowly (<2,000 ft/hr) and start bumping up the cable as thetool approaches surface.

4. Extra precautions should be taken while entering the BOP/riser.

5. Continue bumping the cable until the top of the tool is felt hitting the top of theriser — some resistance will be felt.

6. If there is a tool catcher, verify that the tool catcher is in the CATCH position.The crew member on the cable should bump up one last time with sufficientforce to ensure that the string is “caught.” The winchman can slack somecable to verify that the tool is in the catcher.

7. If there is a tool trap, the winchman should slack off after the entire stringpasses the trap. By resting the string on the trap, verify that the entire stringis in the riser and that the tool trap is in the CLOSED position. This methodavoids hitting the top of the riser.

8. Once it is confirmed that the entire string is inside the riser, the BOP ramsshould be closed.

9. At this point, the WHE can be disconnected and the crew can proceed withrig-down operations.

Reverse procedure is to be applied when releasing toolstring from catcher:

1. Hold cable down mid-way between lower sheave and cable drum whileopening the catcher.

2. Upon feeling the troolstring weight, progressively and slowly release actionon the wireline until confirmed the toolstring is 100% free.

3. Give a signal to the person on the winch to start RIH.

5.4 TLS Operation Guidelines

5.4.1 TLS As Pull-Off Prevention/SafetyThe tension limiter system is used as a safety device to lessen the chance of aninadvertent pull-off during critical operations, such as during rig-up/rig-down, orcoming into casing, riser, or through a BOP.

The winch operator should set the maximum available pressure to slightly morethan that required to lift the toolstring. This will ensure that, should the toolbecome stuck, a sudden increase in tension will be less likely to damage thecable or break the weakpoint. When coming uphole under normal conditions, thesystem can be used to minimize the chance of a pull-off by using the followingprocedure:

1. Switch the tension limiter OFF by turning the control fully clockwise.

2. With the winch joystick, start the drum uphole at the desired speed.

3. Rotate the tension limiter control counterclockwise until a decrease in winchspeed is detected. Then increase the limiter control clockwise approximately15 degrees from this point.

This procedure sets the maximum potential hydraulic pressure to just abovewhat is required to maintain the toolstring at the desired speed. Any increase inline pull due to sticking will cause the winch to stall without inducing dangerouslyhigh cable tension. The tension limiter should be adjusted periodically whilecoming out of the hole, since the required tension will diminish with decreasingdepth. If a change is made to select a different speed range, the tension limitermust also be readjusted.

5.4.2 TLS Used During TLC OperationsGoing Downhole on Pipe

1. After the downhole connector has been latched and the side door entrysub has been clamped, set the winch parking brakes and place the winchspeed switch in HIGH. After HIGH speed has been selected, turn the parkingbrakes OFF.

2. When the tool is run down on pipe, the limiter will usually need to be set atits minimum tension setting. This is because the tension increases slightlyas the driller begins to lower the drillpipe. The static friction of brake andbearings must be overcome to get the drum turning. Place the limiter at itsminimum setting by turning the control fully counterclockwise.

3. Gently move the winch joystick fully in the uphole direction. Allow the cableto become taut and observe the tension. In a deep well with a long length ofhanging cable, it may be necessary to increase the limiter setting slightly toprevent the drum from creeping downhole.

4. Adjust the limiter to provide the minimum acceptable surface tension.

5. The driller may now begin to lower pipe. Some increase in cable tension willoccur as the weight of the pipe begins to pull cable off the winch. Once thedrum is moving, the tension will fall back near preset levels. Always observecable tension during the operation and be prepared to take appropriateaction if necessary.

Coming Uphole on Pipe

1. The winch speed should again be placed in HIGH and the winch joystick fullydisplaced in the UPHOLE position.

2. Set the tension limiter to produce an acceptable surface tension 500 to 800lbf higher than the static tension when going into the hole. Tension will fall offslightly as the pipe is picked up. The drum will then rotate to maintain thetension. It will probably be necessary to operate with the tension limiter set ata higher tension when coming out of the hole than when going in.
