The Bowen Series 150 Releasing and Circulating Overshot is the
strongest tool available to externally engage, pack off, and pull a fish. The basic
simplicity and rugged construction with which it is designed have made it the
standard of all external catch fishing tools.
Construction
The Bowen Series 150 Releasing and Circulating Overshot is composed of three
outside parts: the Top Sub, Bowl, and Guide. The Basic Overshot may be dressed
with either of two sets of internal parts, depending on whether the fish to be
caught is near maximum size for the particular overshot.
If the fish diameter is near the maximum catch of the Overshot, a Spiral
Grapple, Spiral Grapple Control, and Type “A” Packer are used.
If the fish diameter is considerably below maximum catch size (usually a
1⁄2") a Basket Grapple and a Mill Control Packer are used.
Gripping and Releasing Mechanism
The Bowl of the Overshot is designed with helically tapered spiral section in
its inside diameter. The gripping member (Spiral Grapple or Basket Grapple),
is fitted into this section. When an upward pull is exerted against a fish, an
expansion strain is spread evenly over a long section of the bowl and the
compression strain is spread evenly over a long section of the fish. No damage
or distortion results to either the fish or the Overshot. This design permits a far
stronger tool with a smaller outside diameter than is possible with an overshot
that employs a single tapered section which supports slips.
A Spiral Grapple is formed as a left-hand helix with a tapered exterior to
conform with the helically tapered section in the Bowl. Its interior is wickered
for engagement with the fish.
A Basket Grapple is an expansible cylinder with a tapered exterior to
conform to the helically tapered section in the Bowl. Its interior is wickered for
engagement with the fish.
Three types of Basket Grapple are available to meet the need for catching
various types of fish:
The Plain Basket Grapple is standard and will always be furnished
unless another type is specified. It is wickered for its entire interior length. It is
used to catch any plain single diameter fish.
The Basket Grapple with Long Catch Stop has an internal shoulder
located at the upper end, to stop the fish in the best catch position. It is designed
to stop and catch collars and tool joints, with sufficient length left below the
Grapple to allow the joint to be packed-off with a Basket Control Packer.
The Basket Grapple with Short Catch Stop (not shown) has a double
set of wickers of two different internal diameters. It is used to stop and catch a
coupling with a ruptured piece of pipe engaged in its upper end. The upper set
of wickers will catch the ruptured pipe and act as a stop against the coupling,
while the lower set of wickers will catch the coupling.
Grapple Controls are of two types: Spiral Grapple Controls are used with
Spiral Grapples; Basket Controls are used with Basket Grapples.
Grapple Controls are used as a special key to allow the Grapple to move up
and down during operation while simultaneously transmitting full torque from
the Grapple to the Bowl.
Spiral Grapple Controls are always plain; Basket Grapple Controls may be
either plain or include a Packoff. In addition to the Packoff, they may include
mill teeth. See Packoff Mechanism on page 12 for a complete explanation.

In operation, the Overshot functions in the same manner, whether dressed
with Spiral Grapple parts or Basket Grapple parts.
During the engaging operation, as the Overshot is rotated to the right
and lowered, the Grapple will expand when the fish is engaged, allowing the fish
to enter the Grapple. Thereafter, with rotation ceased and upward pull exerted,
the Grapple is contacted by the tapers in the Bowl and its deep wickers grip the
fish firmly.
During the releasing operation, a sharp downward bump places the
larger portion of the Bowl tapers opposite the Grapple, breaking the hold.
Thereafter, when the Overshot is rotated to the right and slowly elevated, the
wickers will screw the Grapple off the fish, effecting release.
The fact that Bowen Releasing and Circulating Overshots require
right-hand rotation only, both during engaging and releasing
operation, is extremely important. This feature eliminates the dangers that
are present when it is necessary to rotate the string in an unscrewing direction.
Pack-Off Mechanism
The type of Pack-off used depends on how the Overshot is dressed and the
operators’ choice.
When the Overshot is dressed with a Spiral Grapple a Type “A” Packer is used.
The Type “A” Packer is a sleeve type. It seals at its O.D. against the inside
of the Bowl. It has an internal lip which seals around the fish. Each Type “A”
Packer is designed to packoff a specific size. A Type “A” Packer should be
ordered for each catch size Spiral Grapple.
Control Packers are used when the Overshot is dressed with a Basket
Grapple. Control Packers are standard with a Type ‘R” (Replaceable) Packer.
The patented Double Lip Packer provides greater sealing ability and reduces the
chance of seal damage during fish engagement. The outer seal is also replace-
able, this allows for field replacement of either seal. The control is also provided
in a Mill type designs. The Plain Control Packer is used when the milling
operation has already been performed prior to the fishing operation. The Mill
Control Packer is used when light dressing is required prior to fish engagement.
NOTE: Only one control can be installed in the overshot assembly at a time! Control
Packers are manufactured for a specific size. One should be ordered to match
each basket grapple size that has been ordered.
Plain Controls are used when no packoff is required. They are installed in
the same location as the Control Packer.
NOTE: The tables on the following pages list all available controls. Refer to those
tables for the proper part number.
Operation:
Engaging and Pulling the Fish
Connect the Overshot to the fishing string and run it in the hole. As the top
of the fish is reached, slowly rotate the fishing string to the right and gradually
lower the Overshot over the fish. Allow the right-hand torque to slack out of
the fishing string, and pull on the fish by elevating the fishing string. If the fish
does not come, start the circulating pumps and maintain a heavy upward strain
while fluid is forced through the fish.
Releasing From the Fish
Drop the weight of the fishing string heavily against the Overshot, then
simultaneously rotate to the right and slowly elevate the fishing string until the
Overshot is clear of the fish.
To release from a recovered fish, follow the same procedure while holding
fish below the Overshot.
Overshot Accessories
The more commonly used accessories for Bowen Series 150 Overshots are
Extension Subs, Oversize Guides, Wall Hook Guides, Milling Shoes, and Lock
Rings. These accessories are illustrated and listed beginning on page 20.
Calculated strength data on all Bowen Series 150 Overshots is listed in brochure
