Logan Series 70 Short catch & Series 150 Releasing & circulating Overshots
Manual A120 • Series 70 and 150 Overshots • Page 1
OVERVIEW
The Logan Series 70 Short Catch Overshot is designed for conditions when the
fish is too short to be engaged with a
standard overshot. The grapple control
is positioned above the basket grapple
rather than below it to allow the basket
grapple to occupy the lowest position in
the bowl. This enables the overshot to
firmly engage and retrieve a very short
fish.
CONSTRUCTION
The Logan Series 70 Short Catch Overshot assembly consists of a top sub,
bowl, basket grapple control, and
a basket grapple. This overshot has no
guide. The basket grapple is inserted
into the bowl from the top. The design
of the bowl allows the basket grapple
to fit in the lowest position. The basket
grapple control finger then fits into the
top of the basket grapple.
OPERATION
Before making up the overshot on the
fishing string and running it into the
well, be sure the overshot is properly
assembled and dressed with the proper
size grapple. Each Logan Series 70
Short Catch Overshot is designed to engage a specific maximum outside diameter. Each overshot can be dressed to
engage any smaller diameter by installing the desired size of basket grapple.
Refer to the Parts Lists on pages 3 – 4.
Check to make sure all of the components are in good working order. Make
up the overshot on the fishing string and
run it into the well. Although the Series
70 Overshot has no guide, the components function in the same manner as
the standard Logan Series 150 Releasing and Circulating Overshot.
When the overshot reaches the top of
the fish, combined rotation and lowering
results in the following:
1. Because this overshot has no guide,
the bottom of the bowl directs the
fish into basket grapple.
2. The grapple expands and the fish
passes into it until it reaches the pin
section of the top sub or the stop of
a basket grapple.
3. The fish is now properly positioned
in the overshot. The tapers of the
bowl will contract the grapple and
securely hold the fish when upward
pull is exerted on the string.
A sharp downward bump positions
the largest portion of the bowl tapers
opposite the grapple and breaks the
hold between the bowl and grapple.
Right-hand rotation expands the
left-hand wickers in the grapple and
the overshot can then be withdrawn
from the fish by elevating the fishing
string.
CATCHING A FISH
Attach the Overshot to the bottom end
of the fishing string and run it into the
hole. The Logan Series 70 Overshot
assembly is rotated to the right and
lowered as the fish enters the expandable grapple. Simultaneous rotating
and lowering is important. With the fish
in the grapple, stop right-hand rotation
and allow the torque to slack out on the
fishing string. Exert an upward pull to
fully capture the fish.
RELEASING A FISH
A sharp downward force (bump) is applied to the overshot to break the hold
of the grapple within the bowl. The overshot is then rotated to the right while it
is slowly elevated to release the grapple
from the fish until the overshot is clear
of the fish. Simultaneous rotation and
elevation is important.
To release from a recovered fish, follow
the same procedure while holding the
fish below the overshot.
PRECAUTIONS
Never rotate the fishing string to the
left while the overshot is engaged with
the fish unless an upward strain is
maintained.
Always bump down the full weight of
the fishing string before starting releasing operations.
MAINTENANCE
Maintenance is simple, but important
to prolong the life of the tool and guard
against mis-runs. Disassemble and
inspect the tool after each use. Check
the grapple wickers for dullness and
replace if necessary. Make other repairs
as required and reassemble.
Paint or grease the exterior of the overshot to prevent rust or deterioration.
Disassembly
1. Using a vise, clamp the bowl between the threaded ends. Remove
the top sub by breaking loose the
threaded connections between the
top sub and bowl.
CAUTION: Excessive force can
distort or crack the bowl. Use only
enough gripping action in the vise
to break the connections. Avoid making heavy tool marks on the bowl.
2. The control must first be lifted out
through the top of the assembly.
Using right-hand rotation, unscrew
and remove the grapple from the
bowl.
Before reassembly, inspect all parts,
especially the grapple. Check the
wickers for damage and wear to
ensure safe operation. Grease parts
as they are reassembled. Grease
or paint the exterior to prevent corrosion.

OVERVIEW
The Logan Series 150 Releasing and
Circulating Overshot is the most versatile and commonly used fishing tool in
the industry. It is designed to externally
engage, pack-off, retrieve, and release
various types of fish, including tubing,
casing, drill pipe, drill collars, couplings,
and tool joints that have been lost
or twisted off or need to be removed
from the wellbore. It is engineered to
withstand heavy pulling, torsional and
jarring strains without damaging or
distorting the tool or the fish. Its rugged
construction, simplicity, and strength
make the Logan Series 150 Releasing
and Circulating Overshot the standard
choice among all external catch fishing
tools.
USE
The Logan Series 150 Releasing and
Circulating Overshot is designed to externally engage, pack-off, retrieve, and
release various types of fish, including
tubing, casing, drill pipe, drill collars,
couplings, and tool joints that have
been twisted off or need to be removed
from the wellbore.
Each overshot is designed to engage,
pack-off, and pull a specific size of
tubing, casing, drill pipe, drill collars,
couplings, and tool joints, or other tools
with smooth outer diameters. With the
installation of proper undersize parts,
they may be adapted to engage and
pack-off smaller sizes.
Logan Overshots are coded (A – E) with
the following strength designations:
• A = Full Strength (FS)
For all torsional pulling and jarring
strain
• B = Extra Full Strength (XFS)
For extreme abuse
• C = Semi Full Strength (SFS)
Maximum strength for special hole
conditions
• D = Slim Hole (SH)
For heavy pulling strains only
• E = Extra Slim Hole (XSH)
For pick up jobs only
Type A (full strength) overshots are
recommended when casing, hole size,
and fish size will permit.
CONSTRUCTION
The Logan Series 150 Releasing and
Circulating Overshots are constructed
of the highest quality material for
strength and efficiency.
Overshots consist of three main external parts: a top sub, a bowl, and a
guide. Internal catch and pack-off parts
are determined by the diameter of the
fish. Each assembly is designed for
a maximum catch diameter. A spiral
grapple, spiral grapple control, and a
Type A packer are used in the overshot
bowl when the diameter of the fish is
near the published maximum catch
diameter of the overshot.
When the diameter of the fish is considerably below the maximum catch
diameter of the overshot (usually 1/2"),
a basket grapple, a mill control packer,
or basket grapple control are used in
the overshot bowl.
COMPONENTS
Gripping and Releasing Mechanism
Top Sub
The top sub is the uppermost component of the overshot assembly. It is
equipped with a customer specified box
connection to assure proper make-up
with the fishing string.
Bowl
The bowl, the major working component
of the overshot, is located between the
top sub and the guide.
The inside diameter features a helix
section that conforms to the exterior
helix of the grapple. This design permits
any expansion or compression strain
to be evenly distributed over the entire
working surface of the bowl, grapple,
and the fish. Any possible damage to
the fish or overshot is minimized.
Guide
The lowermost component of the overshot assembly is the guide. As its name
implies, it guides the fish into the internal gripping mechanism (grapple) of
the overshot. The guide also minimizes
possible damage to the overshot by
blocking the entry of a fish that exceeds
the maximum catch size of the overshot.
Grapples
The grapple fits into the bowl and is the
gripping mechanism of the overshot.
There are two basic types of grapples:
spiral and basket.

Spiral Grapple Control
Spiral Grapple
Spiral Grapple
The left-handed, helix shape of the
spiral grapple conforms to the tapered
interior helix of the bowl. The specially
hardened interior wickers of the grapple
assure positive engagement with the
fish.
Basket Grapple with Short-Catch Stop
Basket Grapple
with Short-Catch Stop
This grapple is used to retrieve couplings that are attached to a ruptured
section of pipe that protrudes above the
coupling. Two sets of wickers, each with
a different inside diameter, are utilized.
The smaller diameter threads catch the
pipe above the collar and provide a stop
so that the coupling can be engaged
by the larger set of threads before being
packed-off by a control packer.
Basket Grapple
Basket Grapple
The basket grapple is a slotted, expandable cylinder with a wickered interior
to engage the fish. Its tapered exterior
conforms to the interior of the bowl.
To meet the needs of various fishing
operations, three types of basket grapples are available: plain (standard),
short-catch stop, and long-catch stop.
Plain Basket Grapple
The plain basket grapple is used when
the milling operation has preceded the
fishing operation. This type of basket
grapple is used to retrieve fish with a
uniform outside diameter. During fishing
operations, the fish passes completely
through the grapple. Wickers running
the entire interior length of the grapple
securely grip the fish. The plain basket
grapple is standard equipment on all
overshots and will always be furnished
unless another type is specified.
Basket Grapple with Long-Catch Stop
Basket Grapple
with Long-Catch Stop
This type of basket grapple is designed
to retrieve tool joints and collars with
sufficient length remaining below the
grapple to allow pack-off with a plain
or mill control packer. The internal
shoulder at the upper end of the grapple prevents the fish from completely
passing through it. This shoulder also
positions the basket control packer
around the fish for optimum pack-off.
Basket Grapple Control
Grapple Controls
A grapple control acts as a key that
transmits torque from the overshot bowl
to the grapple while allowing the grapple to move vertically inside the bowl
during operation. There are two types
of grapple controls: spiral and basket.
Spiral grapple controls are used with
spiral grapples and are always plain.
Basket grapple controls are used with
basket grapples.
Pack-off Mechanism
If circulation is required during the fishing operation, a pack-off mechanism
is required to assure circulation goes
through rather than around the fish. The
type of grapple (spiral or basket) being
used will determine which type of packoff mechanism is used.
Type A Packer
Type A Packer
A Type A packer is used on overshots
equipped with spiral grapples. The Type
A packer sleeve seals its outer diameter against the inside of the bowl. It
has an internal lip that seals around the
fish. Each Type A packer is designed
to pack-off the specific catch size of
each spiral grapple and one should be
ordered for each size grapple.

OPERATION
Outer Seal
Mill Control Packer
Mill Control Packers
A mill control packer is used in conjunction with overshots equipped with
a basket grapple and should be used
when the fish requires light dressing
prior to engagement. A basket grapple
control is used when the fish requires
no pack-off. Mill control packers replace
a plain basket grapple control. The
teeth on the mill control packer are designed only to remove small burrs.
Only one mill control packer can be installed in the overshot assembly at one
time. Mill control packers are manufactured to match a specific basket grapple
size. One mill control packer should be
ordered for each size of basket grapple
that has been ordered.
For areas with extreme pressure, refer
to the special Logan Series 150 High
Pressure Mill Control Packers and High
Pressure Pack-off Assemblies listed on
pages 40 – 41 for more information.
Type R Mill Control Packer
When an overshot is dressed with a mill
control packer and pack-off is required,
a Type R Mill Control Packer is most
commonly used. The mill control packer
is constructed with a molded inner
seal and a replaceable outer seal that
provide a positive seal around the fish.
Seals may be replaced in the field if
required. (Refer to pages 34 – 37 for
Inner and Outer Seal part numbers.)
The plain control packer is used when
the milling operation has preceeded
the fishing operation. The mill control
packer should be used when the fish
requires light dressing prior to engagement. Only one control packer can be
installed in the overshot assembly at
one time.
Type E Control Packer
The Type E Control Packer is constructed with a molded inner seal and
a replaceable outer seal. They are
available in two styles: plain and mill.
Outer seals may be replaced in the
field. (Refer to pages 36 – 37 for Outer
Seal part numbers.)

Inner Seal
Properly assemble the overshot and
dress it with the correct size grapple.
Ensure that all parts are in good, working condition.
In fishing operations, the Logan Series
150 Releasing and Circulating Overshot
will function in the same manner, whether using a spiral or basket grapple.
Install undersized parts if the fish is
smaller than the maximum outside diameter the overshot can engage. (Refer
to tables on pages 13 – 29.)
In hole sizes that are significantly larger
than the fish size, install an oversized
guide (refer to page 31) or a wallhook
guide (refer to page 32) to prevent the
overshot from passing the fish.
Replace the standard guide with the
proper mill guide if the top of the fish
is heavily burred or jagged. (Refer to
Mill Guides on page 33.)
If the upper end of the fish is unengageable, install an extension sub (refer to
page 30) between the top sub and the
bowl.
Connect the overshot to the fishing
string by the top sub and run it into the
hole.
The Logan Series 150 Releasing and
Circulating Overshot requires righthand rotation only, during both engaging and releasing operations. The righthand-only rotation feature eliminates
the possibility of accidental left-hand
unthreading.
Catching a Fish
CAUTION: Always shut off the circulating pumps before lowering the
overshot over the fish.
Never rotate the fishing string to the
left while the overshot is engaged
with a fish unless an upward strain
is maintained.
Logan Series 150 Releasing & Circulating Overshots • 9
Page 10 • Series 70 and 150 Overshots • Manual A120
Slowly rotate the Logan Series 150
Releasing and Circulating Overshot
assembly to the right while it is lowered
over the fish. It is important to combine
rotation and lowering after the overshot
has reached the top of the fish and as
the fish enters the expandable grapple.
The guide will direct the fish into the
overshot. The grapple will expand,
allowing the fish to pass through it and
the pack-off rubber. The fish will stop
when it makes contact with the pin end
of the top sub. If engaging an external
upset section with a basket grapple, the
fish will be stopped by the solid metal
stop in the upper end of the basket
grapple. With the fish properly positioned in the grapple, allow the righthand twist to slack out of the string.
Cease rotation and exert an upward
pull on the fishing string to fully capture
the fish. The upward pull contracts the
wickers in the bowl, thereby gripping
the fish with the grapple and holding it
secure.
If the fish does not advance, maintain
an upward strain on the fishing string
and turn on the circulating pumps to
force fluid through the fish. With the fish
securely positioned, circulation seals
the pack-off rubber around the fish
to prevent fluid from passing down the
outside. The pumps build pressure
to force fluid down through the fish.
Releasing a Fish
CAUTION: Before beginning releasing operations, always bump down
the full weight of the fishing string.
A sharp downward force (bump) is applied to break the hold of the grapple
within the bowl. The downward force
positions the largest portion of the bowl
tapers opposite the grapple and breaks
the hold. The Logan Series 150 Releasing and Circulating Overshot is then
rotated to the right and slowly elevated
to release the grapple from the fish.
As the overshot rotates to the right, the
friction of the fish against the grapple
causes it to unwind and expand. Continue simultaneous right-hand rotation
while slowly elevating the fishing string
until the overshot has cleared the fish.
Combined rotation and elevation is very
important.
Undersized Spiral Parts
When a fish is smaller than the specified maximum catch size of the overshot, undersized parts are used.
Undersized spiral parts (spiral grapples
and Type A packers) are used to catch
fish sizes between the “Maximum Catch
Size (Spiral)” to the “Maximum Catch
Size (Basket).” (Refer to tables on
pages 13 – 29.)
Spiral grapples and type A packers
should be changed for each size of fish.
They will effectively catch and pack-off
a worn fish as much as 3/32" under,
and approximately 1/32" over, the catch
size of the grapple.
Some overshots, especially Logan Oil
Tools code “D” slim hole (SH) type overshots, can effectively catch a fish that
is no more than 1/16" under maximum.
Undersized Basket Parts
Undersized basket parts (basket grapples and mill control packers) are used
to catch sizes smaller than the “Maximum Catch Size (Basket).” (Refer to
tables on pages 13 – 29.) Basket grapples will effectively catch and pack-off a
worn fish as much as 3/32" under, and
approximately 1/32" over, the maximum
catch sizes listed.
Some overshots, especially Logan Oil
Tools code “D” slim hole (SH) type overshots, can effectively catch a fish that
is more than 1/32" under size.
Basket grapples and mill control packers should be changed for each size
of fish. A plain basket grapple control
does not need to be changed to a mill
control packer when using an undersized basket grapple.
Subsea Retrieval
On offshore floating rigs, drill string
extends hundreds of feet from the rig
to the wellhead blowout preventer
(BOP) on the sea floor. Sometimes it
is necessary for the rig to move (in the
event of a blowout, an approaching
storm, or drifting due to loss of anchor)
from a well site. In these situations, the
drill string can be temporarily severed
inside the BOP to remove only the upper end.
The BOP must have at least two sets
of rams — a set of lower pipe rams and
set of shear rams above them. Land the
closest tool joint on the lower pipe rams.
Close the lower pipe rams to suspend
and pack-off the string before shearing. Shearing produces flattened, flared
ends with protruding ears.
The string is retrieved when the rig
returns to the well site. The end is
brought to the surface and the sheared
piece is removed. Often large sections
of the BOP stack must be brought to the
surface as well for effective retrieval,
making subsea sheared pipe retrieval
a costly, difficult, and time-consuming
task.
By removing the standard guide, grapple, and packer, the Logan Series 150
Releasing and Circulating Overshot
can be dressed with a mill extension
and special flat-bottomed guides (refer
to Mill Guides on page 33) to retrieve
sheared pipe in an economical, simple,
and time-saving manner.
Before installing the overshot on the
drill string, dress it with a mill extension
and a flat-bottomed, long guide. The
tapered milling ribs of the mill extension
are faced with sintered tungsten carbide
on the inner diameter. The overshot is
then lowered into the BOP and over the
end of the drill pipe. Rotation mills down
the flared ends and protruding ears of
the sheared pipe. The end of the long
guide (and the short guide) is faced with
10 • Logan Series 150 Releasing & Circulating Overshots
Manual A120 • Series 70 and 150 Overshots • Page 11
soft metal so it will not damage the BOP
pipe rams if it inadvertently comes into
contact with them.
The long length of the guide also prevents the mill extension from touching
and causing damage to the tool joint in
the BOP. This is of utmost importance
as the outer diameter of this joint is
where the string will be engaged.
After milling is completed, The Logan
Series 150 Releasing and Circulating
Overshot is elevated to the surface. It
is then dressed with a flat-bottomed
short guide, an extension sub, a basket
grapple, and a mill control packer sized
to engage the tool joint. The overshot is
lowered again. As the BOP is entered,
the milled flare-end will pass through
the grapple and the mill control packer.
Once in the extension sub, the grapple
will engage and pack-off the tool joint.
Exert an upward pull on the overshot
to ensure engagement. Then retract the
BOP pipe rams. Raise the string to the
rig floor and remove the severed joint.
Replace the joint and resume normal
operations.

OVERSIZED GUIDES
The Logan Series 150 Oversized Guide properly guides
the fish into the over-shot when the hole size is considerably
larger than the diameter of the fish and the overshot may
pass alongside the fish without engaging it. Installation of
an oversized guide instead of a standard guide will ensure
alignment of the fish with the overshot.
When ordering, please specify:

or Bowl

Mill Control
HIGH PRESSURE MILL CONTROL PACKERS
The Logan High Pressure Mill Control Packer (U.S. Patent 6-425-615)
is designed for use with Logan Series 150 Releasing and Circulating Overshots and has been successfully field tested and proven to 5,000 psi. The
unique design utilizes a steel retainer ring that can be easily installed and
removed with an adjustable spanner wrench (Logan Part Number SW1001) to compress the inner seal. (Inner Seals are listed on pages 34 – 35.)
The steel retainer ring is also machined with left-hand threads to prevent
back-off. The body of the Mill Control Packer and the steel retainer ring are
machined with a series of grooves to ensure maximum positive retention
of the inner seal during high pressure operations. Correct steel retainer
ring installation and proper inner seal squeeze are accurately defined
when the retainer ring is flush with the top of the Mill Control Packer body.
When ordering, please specify:
(1) Overshot Assembly to be used with
(2) O.D. of tubing or pipe size to pack-off

and Type A Packers)
OVERVIEW
Logan Lock Rings provide a positive means for locking and releasing
straight-threaded, shouldered joints
that will not back off. Lock Rings are
installed between the top sub and the
bowl, and are designed to keep the top
sub from inadvertently unthreading from
the bowl. Lock Rings are typically used
when a significant amount of torque is
being applied through the overshot to
the fish (such as encountered during
back-off operations). Excessive torque
is not necessary when Lock Rings are
used. Lock Rings eliminate the hazardous practices of using steel straps or
installing set screws to secure the bowl
to the top sub. Lock Rings can be used
with either a basket or spiral grapples.
CONSTRUCTION
Logan Lock Rings are precision machined from stress relieved, heat-treated alloy steel. Lock Rings are used in
pairs and consist of two identical rings
with cam-teeth on one face, knurls on
the other, and two break-out grooves
on the edges.
DISASSEMBLY
The pitch of the cam-teeth is greater
than the thread pitch of the bowl. When
reverse rotation is applied, the camtoothed edges will wedge against each
other to effectively lock the top sub to
the bowl.
ASSEMBLY
Position the rings together so the breakout grooves align and the cam-teeth
are intermeshed. Place the lock rings
on the top sub. As the bowl is threaded
and the tool joint made-up, the knurled
faces opposite the cam-teeth will grip
the shoulders.
Heavy make-up torque is not neccessary. Joints are properly made up when
reverse rotation is applied and the camteeth shoulders slightly separate.
A spacer is required if the overshot is
dressed with a spiral grapple and a
Type A packer. The spacer is installed
into the bowl and on top of the Type A
packer. The spacer fills the void produced by the extra standoff caused by
the top sub and lock rings. A spacer
is not required when a Type A packer
is not used.
42 • Logan Series 150 Releasing & Circulating Overshots
A special breakout clamp (Logan Part
No. A13000-001) is required when
unthreading is desired. Slight right-hand
torque may be needed to align the
breakout grooves so they may receive
the clamp. The breakout clamp consists
of two keys that fit into the lock ring
grooves — a lower key seat and
a movable key seat that is attached to
a bracket guide and a screw handle.
A linked chain is attached at one end
to the bracket guide.
Back out the screw handle as far as
it will go. Position the breakout clamp
by placing the keys in the ring grooves
opposite each other. Insert one end
of the linked chain into the hole in the
lower key seat. Pull the chain around
the rings and remove all slack. Slip
the chain pin closest to the pin slot onto
the bracket. Tighten the screw handle
to force both keys into the breakout
grooves. When the grip is broken, the
keys will hold the cam-teeth together
and allow the shoulders to back away
from the knurled faces.
