RigRig--up Equipmentup EquipmentSome of the Basic Equipment is also referred to as Rig-up equipment since these components allow us to ‘Rig-up’ our equipment at the Well-Site and are essential to running a Wireline operation.2

This basic sketch shows the rig-up equipment which will be discussed in this section.

Sheave WheelsSheave Wheels22

Sheaves are pulley wheels with a grooved rim that allow the safe movement of the Wireline

Cable from the Truck/Unit to the well.

Different wheels are used depending upon the type of

cable used and the type of operation.

Normally 2 sheaves are used in a rig-up

(lower Sheave and upper Sheave)

13 in Stainless Steel wheels

used in Monocable, {Cased Hole and production operations}

Nylon compositesheaves available for

both MONOCABLE and HEPTACABLE

operations

36 in Upper Sheave (with no finger guard)

36 in Lower Sheave (with finger guard)

36 in Standard Sheave Wheels used in Heptacable Operations (mostly Open-Hole operations)

{Shown above and below}.

Vertical MakeVertical Make--Up Plate (CUp Plate (C--Plate)Plate)22

These allow the safe connection and disconnection of Wireline Tools on the Rig-floor.

There are several types depending upon the types of tools being connected.

Standard Open Hole C-plate Heavy Duty Make-up Plate used for long and heavy tool-

strings

Standard Mini C-plate used for cased-hole operations



June 06


Sheave Hangar and WireSheave Hangar and Wire--SlingSling22

Sheave Hangar: Also known as a spade is used to connect between the upper sheave wheel and the Elevator of the rig.

SLING: Safety device used to tie the Sheave hangar to the Elevators in case the elevators come open

(Upper Sheave side)

(Elevator side)

TieTie--Down Chain and GooseneckDown Chain and Gooseneck22

TIE-DOWN CHAINA tie-down chain is used to anchor the lower sheave to the rig superstructure. It has 5/8-in. diameter links and is available in 10-, 20- and 30-ft. lengths.

GooseneckThe gooseneck is used to create a smooth bending

radius between the cable and tool head. This prevents cable damage at the head when lifting

tools from the catwalk. The longitudinal arm prevents the gooseneck from passing through the

rotary table.

ShacklesShackle is used to tie the Lower

sheave wheel to the Tie-down Chain

MultiMulti--meter, Megger, Safety Metermeter, Megger, Safety Meter33

Safety MeterThese are specially designed meters to limit the current output (<25 mA).

This is the ONLY meter that can be used to check EXPLOSIVES circuits.

Megger (Megohmmeter)The Megger is designed to

check electrical insulation by sending 500 or 1000 V through the

system.

It is used to check insulation of Cables/Heads/Adaptors

[Must NEVER be used to check EXPLOSIVES or LOGGING TOOLS]

Multi-Meter [Simpson]

This meter is used to measure resistance, voltage and Current.

It is used to check continuity of electronic cartridges and circuits in Logging tools

Electrical Logging Cables (The Wireline)Electrical Logging Cables (The Wireline)3,Section 33,Section 3

There are 2 main types of cable represented by the number of wire conductors; HEPTACABLE (7 conductors shown above) and MONOCABLE (1 conductor shown right ).

Within each type, there are a number variations depending upon the material used for the INSULATION and JACKET and also the treatment of the ARMOUR. These changes will give the cable different electrical and mechanical properties.

You will learn to recognize the properties of the cable by its name and designation.

Logging CablesThe logging cable is the basic tool required for Wireline work

The primary Functions of the cable are :

Provide mechanical support of the down hole tools

Electrical Connection and communication with down hole tools

Used mainly for CASED HOLE & PRODUCTION

Operations

Used mainly for OPEN HOLE Operations



June 06


Cable IdentificationCable Identification3,Section 33,Section 3

All logging cables have a standard nomenclature (naming format) that tells you the properties

of the cable. It is important to use the right cable for the right type of job. Here is the

nomenclature:

7 - 46 N T XS 1234 MP

Gives Additional Information about the cable Armour.(Blank if standard)

# of Conductors O.D. in/100(e.g. 46 = 0.46in

Diameter) Serial #Insulation

Material Electrical Insulation Mechanical Toughness

Insulation“P” = Ethylene Propylene Copolymer insulation (EPC) Good Excellent“V” = Vectorene insulation (TPX) with Nomex tape Excellent Excellent“Z” = Tefzel™ bedding and/or insulating material Fair Excellent “T” = Teflon™ insulation Excellent Fair

Jacket“N” = Neoprene jacket material Poor Good“Z” = Tefzel™ bedding and/or insulating material Poor Excellent

Cable PropertiesCable Properties3,Section 33,Section 3

These are the main Jacket and Insulation materials (a more complete list is given in the notes of this slide)

Cable Safe Working loads

Standard Heptacable = 8345 lbs

XS Heptacable = 9705 lbs

Standard Monocable = 2945 lbs

Other Suffix

“XS” = Extra Strength

“MP” = Multi-phase (means H2S gas resistant)

FIT and TRIMFIT and TRIM33

FIT: Fast Inspection of Tool:Maintenance to be done on tools and equipment BEFORE and AFTER each job.

THREE TYPES:

1. FIT-1 – Mechanical : Cleaning, greasing, Change seals, O-rings changes, Filling oil.

2. FIT-2 - Electrical : Check insulation and continuity of the circuits.

3. FIT-3 – Operational Check : Check the tool under simulated operating conditions

NOW GO AND DO FIT AND TRIM OF THE TOOLS MAIN LOGGING TOOLS USED IN THE LOCATION(under supervision of your Crew-Chief)

TRIM : TOOL REVIEW and INSPECTION MONTHLY:Maintenance to be done on tools and equipment every MONTH.

THREE TYPES:

1. TRIM -1 - Mechanical : Opening enclosed housings, checking internal seals.

2. TRIM -2 - Electrical : Check insulation and continuity of the circuits.

3. TRIM -3 – Master Calibration : Calibrates sensors according to design and then Operational Check.



June 06


RITE MethodologyRITE Methodology33

RITE: Routine Inspection of Tools and Equipment:This is a system of procedures (METHODOLOGY) to sustain operations through preventative maintenance and product modifications.

There is a RITE database program used to track all the TOOLS and Equipment in the location, their maintenance and modifications.

RITE also records all the history of the jobs done by the tool and any failures that have occurred.

SYSTEMS THAT MAKE UP RITE:FIT and TRIM

Q-Checks : detailed inspections and quality check of tools at specified intervals (usually Quarterly)

Tag system to ensure that only fit and worthy tools are in operation:

1. Green Tag : Tools fit and ready to go on a job.

2. Yellow Tag : Intermediate tags to specify things such as ‘repaired’.

3. Red Tag : Equipment that has failed to function. Must be accompanied by a Failure report.
