Economics – When to quit fishing?
D = ( V + Cs ) ÷ ( Fd + Rd )
D = Maximum days to fish
V = Value of fish
Cs = Cost of sidetrack
Fd = Fishing daily cost
Rd = Rig daily cost
Cost of sidetrack = $ 500,000.00
Value of fish = $ 500,000.00
Fishing daily cost = $ 20,000.00
Rig daily cost = $ 120,000.00
( 500,000 + 500,000) ÷ ( 20,000 + 150,000)
(1,000,000) ÷ ( 170,000) = 5.9 Days to fish
What this simple formula does is set the rule of time. It does not
address the probability of success or the risk associated with
failure. It is critical to address the probability of success and the
cost of failure in the decision process before starting a fishing job.

You are stuck! What is next?
There are three questions that I always ask regarding stuck pipe. These
questions are specifically suited to address open hole sticking conditions
but can also used very effectively in cased hole applications. These
questions are as follows:
Stuck Pipe Question # 1
Was the pipe moving when it became stuck?
YES or NO
YES – What direction was the pipe moving?
UP – Keyseat Sticking, Under Gauge Hole, Differential Sticking
DOWN - Under Gauge Hole, Differential Sticking
Rotating – ( There is no change in hydraulic properties.) Differential
Sticking
NO - ( There is no change in hydraulic properties.) Differential Sticking
NO – ( with a change in hydraulic properties, reduced flow, higher
pressures or both) Sloughing Hole
Page 4
Key Energy Fishing Services
Stuck Pipe Question # 2
Are the hydraulic properties the same or different than
before the pipe became stuck?
YES or NO
Yes – Differential Sticking, Keyseat Sticking, Mechanical Sticking
No – Well Bore Geometry – Sloughing Hole, Under Gauge Hole
Stuck Pipe Question # 3
Have you done a manual stretch calculation to estimate
where you are stuck?
Whenever pipe becomes stuck, always calculate the estimated depth at
which the pipe is stuck by measuring the stretch in the stuck pipe at a
given pull over string weight. My favorite formula is as follows:
(2208.5) x (nom. wt. of tube in pounds per foot) = the over pull
necessary to induce 3 ½” of stretch per 1,000’ of free pipe.
Page 5
Key Energy Fishing Services
Manual Stretch Calculation
Formula to Calculate Stuck Point
(2208.5) x (Nominal Weight of Tube (lbs/ft)) = the over pull over
string weight necessary to induce 3 ½” of stretch per 1,000 feet of
free pipe.
The stretch calculation listed above comes from the McCullough
Tool Company and is over fifty years old. It includes the tool joint
area. If you have coil tubing, wire line, or flush joint pipe, use 3” of
stretch per 1,000’ of free pipe and it will work very well.
Buoyancy - Do you include or exclude the effect of buoyancy in
the manual stretch calculation?

Pipe Recovery
Free Point Indicator
All free point indicators read stretch, compression, and right hand
torque.
The new generation of free point indicators also read left hand
torque.
Free point indicators read the actual movement of the pipe body
between the anchors on the Free Point Tool – 30/1,000” Stretch
and 15/1,000” Torque would be an average reading.
Max rating on some but not all free point indicators is up to 475
degrees F and 21,000 PSI pressure.
The patent for the first free point tool was issued February 11,
1941.
Cardinal Rules of Pipe Recovery
Cardinal Rule Number One : Free Point - Pipe is free or stuck.
Always leave free pipe above the stuck point if you intend to fish
this well. One or two joints above the stuck point is recommended.
Always check torque and stretch.
Page 10
Key Energy Fishing Services
Free Point Tool - Anchors
A free point tool reads on the average of 30/1000” movement in stretch reading
and 15/1000” movement in torque reading.
Magnet Bow Spring Centralizers Motorized Anchor
Four Types of Anchors are available.
• Bow Spring Anchor (Carbide Buttons)
• Permanent Magnets
• Electromagnet
• Motorized Anchor

Pipe Recovery Log ( also called a Stuck Pipe Log)
A pipe recovery log or stuck pipe log is actually a single receiver cement bond log.
A pipe recovery log can be extremely valuable in planning the fishing job because it
gives us information about the well situation below the stuck point.
A pipe recovery log is best suited for open hole use but can be used in cased hole.
Pipe recovery logs do not work well in horizontal wells in the lateral.

Ten Sticking Conditions Approximately sixty years ago the McCullough Tool Company identified the ten sticking
conditions that are involved whenever pipe or tools become stuck in a well bore either cased
hole or open hole. Whenever pipe or tools become stuck it is critical to identify the problem by
addressing what is the sticking condition or conditions that have caused you to become stuck.
The ten sticking conditions are listed below.
Differential Sticking
Key Seat Sticking
Blow Out Sticking
Sloughing Hole Sticking
Lost Circulation Sticking
Cemented Sticking
Mechanical Sticking
Under Gauge Hole
Mud Stuck
Sand Sticking
Page 14
Key Energy Fishing Services
Differential Sticking is a major problem in
drilling operations worldwide.
Differential Sticking
The most common cause of differential sticking is
thick filter cake across a permeable zone.
Preventive Action
Reduce wall contact with B.H.A. using spiral drill collars,
H.W.D.P., and stabilizers.
Maintain minimum mud weight.
Daily short wiper trips when hole drag is observed.
Keep drill string moving. Consider rotating drill string
while standing back pipe or picking up a stand or single
when making a connection.
Spotting Agents
Local knowledge is critical as to what spotting agents work
in a geographic area, and what is the average time that a
spotting agent needs in order to free the stuck pipe.
If you choose to spot oil, diesel, or Black Magic®, pump
enough to cover the B.H.A. and be able to pump ½ barrel
every hour while waiting for the pipe to come free.
Page 15

Differential Sticking The example shown below calculates to have a sticking
force of 1.2 million pounds.
Differential Sticking - Jarring Recommendation
If drilling jars are in the hole and are working, apply torque and jar down if the bit is not on
bottom. If the bit is on bottom jar up. Do not jar down with the bit on bottom.
Jarring option by itself is rarely successful because the hydraulic force sticking the pipe is so
strong. Spotting a pipe releasing agent usually works even if jars are also needed to free the
pipe.

Key Seat Sticking – A key seat occurs when drill pipe in tension wears a slot (key
seat) in the wall of a hole during drilling operations. This happens when a well deviates from
true vertical, controlled or not controlled.
Preventive Action
When it becomes evident that a key seat is forming,
wipe it out with a key seat wiper or string reamer
before it sticks your drill string.
Indication of Key Seat Sticking Pipe was moving up when it became stuck.
Pipe is usually at an O.D. enlargement or stiffness
change in the drill string.
Circulation is not affected in any way.
Pipe may be able to be rotated but not reciprocated.
Recommended Procedure
Surface Jars – DO NOT hit down with surface jars
at a setting higher than the weight of the available
free pipe or the rebound will stick the pipe tighter.
Back-off – Leave a minimum of two joints of free
pipe above the stuck point to insure that the top of
the fish will be above the top of the key seat.
Jarring Option – Screw-in with jarring assembly
with enough drill collars to effectively jar down.
Wash-Over - Typically a short interval to wash-
over.
Page 17
Key Energy Fishing Services
Blowout Sticking
Page 18
Key Energy Fishing Services
Sloughing Hole Sticking or Lost Circulation Sticking
Sloughing Hole Sticking – Usually occurs immediately
below a cavity. The most common cause is poor filter cake
across an unstable zone. A warning sign is hole fill during
connections or trips. Indication of sloughing hole is pipe is
stuck and hole is packed-off. Circulation is greatly reduced or
impossible.
Recommended Procedure – If circulation (although at a
reduced rate) is possible, jarring is an option that has merit. If
the hole is packed-off, the success rate of jarring is almost nil.
Wash-over is the option that will work. Dimensions of B.H.A.
and well bore and mud properties will dictate the risk factor of
this option.
Lost Circulation Sticking – Can occur after losing
circulation.
Recommended Procedure – If circulation (although at a
reduced rate) is possible, jarring is an option that has merit. If
the hole is packed-off, the success rate of jarring is almost nil.
Wash-over is the option that will work. Dimensions of B.H.A.
and well bore and mud properties will dictate the risk factor of
this option.
Page 19
Key Energy Fishing Services
Cemented Sticking
When pipe is cemented in place, jarring is not an option except
on a very short section of pipe.
Recommended Procedure
Open Hole-
Cemented in pipe can usually be washed-over if economics will
allow it.
Cased Hole –
Wash-over will be a problem in cased hole unless the pipe being
washed-over is centralized in the hole (and it almost never is).
During wash-over, when the pipe being washed-over is not
centralized, a pinch point will be reached where either the wash
pipe will simply not make any more progress at all, the wash pipe
will become stuck, or the well side-tracked. Selecting a very
aggressive mill and milling up pipe may be the best option. If a
pilot mill is selected, the pilot must be small enough O.D. to allow
the blades to sweep the hole from side to side where the pipe
being milled is not centralized.
Page 20
Key Energy Fishing Services
Undergauge Hole Sticking
Identity if the undergauge hole is above or below the bit. If a bit
was stuck in undergauge hole while tripping in the hole, jarring up
is usually successful. If the undergauge hole occurs above the
B.H.A. due to a plastic shale or salt section and circulation
(although at a reduced rate) is possible, jarring is an option that has
merit. If the hole is packed-off, the success rate of jarring is almost
nil.
Wash-over is the option that will work. Dimensions of B.H.A. and
well bore and mud properties will dictate the risk factor of this
option.
Mechanical Sticking
Mechanical sticking occurs due to junk or a foreign object in the
hole. Circulation is usually nor affected.
Recommended Procedure Free point and part pipe at appropriate place. Run attachment
tool with jarring assembly that will enable you to effectively jar
both up and down.
Page 21
Key Energy Fishing Services
Sand Stuck Mud Stuck
Sand Sticking or Mud Sticking
The greatest risk is that during pipe recovery while reciprocating the pipe, a pocket will
be formed in the sand or mud that will cause the free point tool to show free pipe, but the pipe
cannot be pulled. Take the free point reading at a higher pull value than when the pipe was
being reciprocated if think Sand Sticking or Mud Sticking is probable.
Recommended Procedure – If circulation (although at a reduced rate) is possible, jarring is an
option that has merit. If the hole is packed-off, the success rate of jarring is almost nil.
Wash-over is the option that will work. Dimensions of B.H.A. and well bore and mud
properties will dictate the risk factor of this option.

Pipe Recovery How to part pipe
Preferred method in alphabetical order if fishing is an option.
. Back-off ( with string shot explosive)
. Chemical Cut
. Jet Cut
. Mechanical Cut ( Internal)
. Split Shot®
If side-track is the option, a Severing Tool can be run.
Back-off ( with string shot explosive)
Prior to putting in left hand torque, the pipe to be backed-off should be tightened by putting
in right hand torque by turning the pipe to the right. Do not exceed make-up torque. When you
put in the right hand torque, count the rounds, stopping when make-up torque is reached.
Reciprocate the pipe which will work the torque down hole to the stuck point. Release the
torque slowly counting the rounds that you get back. When you get the same number of rounds
back that you put in, the pipe is properly tightened and is ready to put in the left hand torque
The rule-of-thumb for how many rounds to the left is as follows;
Drill Pipe - ½ - ¾ Rounds to left per 1,000’ of free pipe
Tubing - 1 Round to left per 1,000’ of free pipe
Fire the shot with the string shot rod across the connection to be broken.
Checking the break
After the initial break is made to the left, pull the collar locator up hole two connections plus
ten feet and stop . Make a note of what depth the second connection is. Finish unscrewing the
pipe and pick up the backed-off pipe five feet. The connection below the collar locator should
have moved up the hole five feet. Check this with the collar locator. Do not go lower than the
break with the wire line tools . Trip out with wire line tools. Trip out of hole with backed-off
pipe.

String Shot Back-Off
Advantages of a back-off
. A back-off leaves a connection to screw back together not depending on a rubber pack-off
if circulation through the fish is critical as it always is in open hole fishing.
. Can be run through smaller I.D.’s than cutters.
. High mud weights do not adversely effect a string shot back-off.
. Temperature – Prima-Cord is available to handle well bore temperatures up to 525 degrees F
for one hour.
. String shot can be run in combination with a free point indicator if the well conditions
warrant it.
Five requirements for a successful back-off (Value Order Listed)
. The connection to be backed-off must be free.
. The shot must be fired across the connection.
. The connection being shot must be at neutral weight.
. The correct amount of left hand torque must be applied.
. The proper size string shot charge must be run.

Page 26
Key Energy Fishing Services
Chemical Cutter
Advantages of a chemical cutter
. O.D. and I.D. of fish are unchanged and are suitable to be fished with an overshot or a spear.
. Chemical cutter will NOT damage an adjacent string.
Disadvantages of a chemical cutter
. Heavy mud (above 15 ppg) can be a problem.
. Hold down buttons can punch through corroded tubing.
. Well temperature limitation – 300 degrees F for one hour.
. Wall Thickness – Poor track record in attempting to cut greater than 0.45” wall.
. Hypergolic – Bromide Triflouride must contact liquid for the cutter to work.

Jet Cutter Advantage of jet cutter
. Short assembly – will go places a chemical cutter will not pass.
. No hold down buttons. Scale or coatings on the I.D. of the pipe to be cut have
little effect on the jet cutter.
. Greater size range than the chemical cutter.
Available sizes to cut from 1” CT – 13 3/8” Casing.
Disadvantage of jet cutter
. Can damage adjacent string unless cut is made in centralized area.
. Flares the O.D. of the fish requiring it to be dressed off if an overshot is to be run.

Owens Split Shot®
. A linear shaped charge of relatively small diameter.
. Designed to split a collar or connection with no distortion of the pipe.
Advantages of Owens Split Shot ® . Can be run in very thick mud.
. Can be run through major I.D. restrictions such as spears without re-heading the
wire line.
Disadvantages of Owens Split Shot ® . If pipe is integral joint not coupled, multiple trips will probably be needed to complete the
cut if the Owens Split Shot® is run.
. The split coupling could come out with the upper section of pipe retrieved or stay on the
bottom section of pipe left in the hole or fall off on top of the fish while tripping out.
Severing Tool
. The severing tool usually eliminates all fishing options. It should be use when side
track or P&A is the next option.
. Open Hole Use Only
. When attempting to sever pipe not drill collars, fire the severing tool in the tool joint
or coupling. When a severing tool is fired in the tube of pipe it usually will balloon
and rail spilt the tube but not part the pipe. The severing tool needs the mass of
a drill collar or tool joint in order to work properly.

Bottom Hole Junk Shot
This is actually a large perforating charge pointed downward rather
than to the side.
The nose cone on the charge must actually touch the junk at the bottom
of the hole.
Even though this is a directional charge pointed downward there are
tremendous forces generated to the side. Because of this NEVER RUN

Overshot Series 150 – Accessories – Top Sub
The top sub for an overshot is nothing but a crossover sub for the thread form of the bowl
and the thread form of whatever it is attached to. An important thing to remember is that if
the top sub for the overshot has a tool joint connection there will be a reduced I.D.
through that connection as there will be in the jars and the drill collars if they are run.
The thread form on the top sub pin is a coarse load bearing torque bearing thread.

. The I.D. of an upper extension is always less that the maximum catch of the overshot.
. The thread form on the upper end of the overshot bowl is load and torque bearing.
. The thread form on the lower end of the overshot bowl is a fine thread and is not designed
to be load or torque bearing.

Overshot Series 150 – Basket grapple with built-in STOP
If the fish top has an O.D. change from larger on top and
smaller below and is short enough to pass above the grapple inside
the overshot, a STOP must be run or the overshot will not release.
A grapple with a built in STOP reduces the overshot strength by an
average of 35% because it reduces grapple contact area on the fish.

Hydraulic Fishing Jars
Bowen developed the first hydraulic fishing jar in 1950. It was the Bowen Type Z .
Below is a drawing of the Bowen style timing device which is used in the dual action
hydraulic fishing jar. When the jar releases, the hammer hits the anvil and a stress wave
heads to the surface traveling at the speed of sound. All of the energy released by the
jar is produced by the pipe above the jar.
Jar is in cocked position. Jar has released.

Key Energy Fishing Services
Drill Collars or H.W.D.P. ?
Whenever you run jars it is prudent to run weight material. The weight material can be
H.W.D.P. or drill collars. What the jar manufacturer is looking for is weight to include in the
equation that calculates impact and impulse. If you run H.W.D.P. instead of drill collars it is a
two for one exchange. In other words you would need to run twice as many joints of equivalent
sized H.W.D.P. as you would run drill collars to approximate the same available weight.
How many drill collars?
Rule of Thumb for Selecting Number of Drill Collars to Run.
Match the O.D. of your drill collars and jars and that number will be the minimum number to run. The maximum will be the minimum multiplied by two.
Example: 6 1/4” Jars and 6” DC Min = 6 Max = 12 H.W.D.P. is a two for one exchange Example: 3 ¾” Jars and 3 ½” DC Min = 4 Max = 8
Another way of looking at the rule of thumb is one drill collar for each O.D. inch of the jars
that are being run for the minimum. The maximum would be two drill collars per O.D. inch of
the jars being run.
This Rule of Thumb should only be used when the jars are placed two joints or less from the
stuck point. If you are outside of this two joint window you need to run a jar placement
program in order to know how many drill collars to run.
Page 92
Key Energy Fishing Services
Fishing Jar Program – NOV Bowen
Jar Placement - Two joints or less from the stuck point if appropriate to well
bore conditions and casing seats. The rule of thumb for how far to back-off pipe
from a casing seat in open hole is a minimum of 100’.

Jarring Operations
How long are you going to jar assuming there is no
movement either up or down ?
Chevron data based their jarring operations world wide. Their
conclusion based on the data base was with no progress in moving
the fish up or down the maximum time to jar is 4 – 5 hours.
What I wish Chevron would have done would be to separate cased
from open hole and in my opinion maximum time to jar would be:
Cased Hole – (Mechanically stuck major portion of time.) Jarring
time - 2-3 Hours
Open Hole – ( Many different sticking mechanisms .) Jarring time
10 – 12 Hours
The key words in the data base from Chevron are ‘NO
MOVEMENT’. If you are moving the fish at all either up or down,
be patient, keep doing what is working and you can almost always
work the fish out of the hole.
Page 94
Key Energy Fishing Services
Four Elements of Effective Jarring
In any jarring operation make sure you have met each of the four elements listed
below or you are not efficiently jarring UP on the fish.
1. Restricted Pull
a. You must be stuck.
b. Restricted pull device ( Oil Jar )
2. Multiplier ( Drill Collars or H.W.D.P. )
If you do not run drill collars or H.W.D.P. ,the multiplier is less than one.
3. Transition Area
a. The change in mass from drill collars/HWDP to pipe is an acceptable transition
area. NOV Bowen calls this a reflective area.
b. A Jar Accelerator®/Booster®/Energizer®/Intensifier® is the most effective and
efficient transition or reflective area.
4. Stored Energy

Wash Over Shoe Design
A shoe must cut clearance in order keep from getting stuck and get the
mill cuttings to the surface.
CASED HOLE SHOE – SMOOTH O.D. TO PROTECT CASING I.D. –
Cuts clearance on the I.D. by turning down the O.D. of the fish.
OPEN HOLE SHOE – ROUGH O.D. ( Can be rough or smooth I.D. )
Usually smooth I.D. to protect the dimensions of the fish being washed over.
Wash Pipe String Design
The most common wash pipe connection is Hydril WP® . It has two torque shoulders on
the bottom of the pin and the top of the box. This connection averages about a 50% connection
efficiency which means the connection is 50% as strong as the tube as far as pull force is
concerned. Each size of WP connection has a published torsional yield for maximum torque.
This wash pipe connection is flush joint. It has no reduction in I.D. or increase in O.D.
Another wash pipe connection that is in use today is the Hydril 511 Series® . It has a
hook thread that makes it a superior connection when operating in a curve that applies side-
load when the pipe is rotated. The down side of this connection is that there is a slight
reduction through the I.D. of the pin.
Page 98

Wash Over Operation
How much wash pipe can you run?
. Cased Hole – You will reach the economic limit of how much wash pipe
to run in most cases before you reach the practical limit.
. Open Hole – You must come up with a plan that enables you to fish the well
in a time frame that is economic. If it is necessary to run more wash pipe than
seems prudent for you well configuration, then you may want to go to side-track
without ever starting the wash over operation.

Can the well be circulated?
Option 1 : Slow the pump down to ½ BPM during the milling process.
Option 2: Dry Drill – Pump 3 barrels to start the milling, dry drill for 15
minutes, then pump another 3 barrels.
Option 3: Spot a pill, sand or calcium carbonate across the perfs before the
production tubing is cut.
Option 4: Reciprocating bailer – Use the existing fluid in the well bore.

Packer Milling – Permanent Packers – Shoe Dimensions
Rule Number One: Shoe O.D. = Bit Size
Rule Number Two: Shoe I.D. – Packer MUST be O.D. fishable with an
overshot after mill over is completed.
Rule Number Three: In high angle wells, shoe I.D. MUST be the same as
packer mandrel O.D.
Packer Milling – Permanent Packers – Milling Shoe Design Flat Bottom or Wavy Bottom ? Both will do the job.
Packer Milling – Permanent Packers – Optimum R.P.M.
Optimum R.P.M. for shoe or mill : 1500 ÷ 3.1416 ÷ O.D. of shoe or mill in
inches
Example : 1500 ÷ 3.1416 ÷ 6 = 80 RPM
If you are running an inserted shoe or mill the recommended RPM would be
1.5 to 2 times as fast as the conventional crushed carbide milling tool.
Packer Milling – Permanent Packers – Weight on Shoe
Maximum Weight on shoe or mill :
Crushed Carbide = 250 pounds per square inch
Carbide Inserts = 500 pounds per square inch
On anything other than a whipstock operation, mill by torque if possible. If
whatever you are milling is spinning you apply weight to slow or stop the
movement of the fish. Additional weight is applied as necessary until milling
progress is made. The last resort is shutting the pump down and dry drilling in
order to stop the fish from spinning.

(Cable Guide Assembly )

Key Energy Fishing Services
Fishing Logging Tools – Cut & Strip Method (Cable Guide Assembly)
If a logging tool becomes stuck in open hole, do not pull out of the rope socket. It is much
safer to cut the electric line at the surface and strip over the e-line using it to guide the overshot
to the logging tool. Start the process by pulling a strain on the e-line equal to the weight of the
line in the hole. Install a T-bar clamp on the e-line. Set the T-bar on the rotary table. Cut the e-
line at least ten feet from the clamp plus any additional amount that you deem necessary for
well conditions. Install spear point rope socket on the lower part of the e-line. Feed e-line
through both upper and lower pulleys. Place upper pulley in derrick above the derrick man’s
monkey board and the lower pulley anchored at the rig floor.
Install the rope socket, weight bars or weight cable, and spearhead overshot on the upper
part of the e-line. Latch the spearhead overshot onto the spear point. Pull test the rope sockets
to the maximum that will be pulled on the e-line before removing the T-bar clamp. Make up a
Series 150 overshot with appropriate sized grapple with doughnut guide on the bottom of the
first stand of drill pipe to be run. I prefer to run an upper extension and fish the logging tool
body rather than a fishing neck. The derrick man will place the spear point overshot assembly
in the top of the drill pipe stand. The e-line truck will lower the spear point overshot until it is
hanging below the Series 150 overshot. Latch the spear point overshot onto the spear point
rope socket . Line weight is picked up until the T-bar clamp is picked up above the rotary table.
The T-bar clamp is removed, the Series 150 overshot is slowly lowered into the hole and the
stripping job has begun. An option to consider after one stand or one single joint of is run in the
hole is to install a larger O.D. sucker rod box below the spear point rope socket on the lower
part of the electric line cable. The O.D. of the box should be large enough that it will not go
through the top sub of the overshot being used to catch the logging tool. If necessary a reduced
I.D. sub can be placed on top of the overshot that will stop the sucker rod box from passing.
The purpose of this No-Go is to prevent the stripping tools from falling out of the drill pipe if
something goes awry in the strip over process and the lower portion of the wire line is dropped.
Once the lower overshot has engaged the logging tool, I personally prefer to pull the
spearhead overshot high enough above the rotary table that the t-bar clamp can be installed on
the lower portion of the wire line and then use the rig blocks to pull out of the rope socket at
the logging tool. The company person in charge of the rig will make the decision as whither to
pull out of the rope socket with the t-bar clamp and the rig blocks or strip or not.

Fishing Parted Wire Line If you are unfortunate enough to have parted wire line in your well in open hole or casing ( any tubular that you cannot pull), you are one bad decision from losing your well. Be very deliberate in making any decisions and involve people who have successfully fished wire line in open hole and casing. A person might think that wire line when parted or pulled into in open hole or casing will fall down the hole and ball up. This assumption will junk your well. Wire line (slick line, swab line, electric logging cable) will stand up in the hole very well. The Rule of Thumb that I use is the 10% Rule. Wire line will stand up in the hole 90% or more of its original height in the well. Shrinkage or stacking out will be 10% or less. There are two reasons why the wire line stands up and do not fall to bottom like a child’s toy called a slinky. One of the reasons that wire line stands up is that these steel wire lines come to your location on a drum. The steel gains a memory of the helix of the drum and when it is parted or relaxed in the hole, the wire line will try to return to the helix of the drum it was stored on. This memory makes the wire line to stand up in the hole. The second reason that wire line stands up in the hole is that the rotation of the earth is to the right. The influence of that rotation causes the wire line to spiral to the right and makes the wire line stand up in the hole. The recommended fishing procedure for parted wire line is as follows: RUN ON PIPE Rope Spears – Center Spears – Crank Shaft Spears – Two Prong Grab Spear must have appropriate size barbs to catch a specific size wire line. Open Hole - Never run a stop ring in open hole. Cased Hole – Proper size stop ring usually should be run with spear. Have a selection of rope spears on location. Typically first run will be a center spear. be prepared to make a number of trips as the fishing job is actually a trial and error process to find out what works with the well configuration and the fish in the hole. A person might think that wash pipe could be run and recover large amounts of wire line. What I have found to be the case is that the wire line will ball up as you go down hole and bridge off about one foot in the shoe and then twist into. When you can no longer make any hole you will trip out. The balled up wire in the shoe is a mirror image of what was left behind in you hole. I do not recommend running wash pipe to recover wire line in open hole or casing.
