menstrual cupIntervention, Retrieval, and Recovery
NOV Downhole is the manufacturer of Bowen ® Fishing Tools, the world’s most respected and reliable fishing tool products in the oil and gas industry for over 85 years. Fishing Tools are utilized in two types of operations. 1. Well Intervention – the operation of rvicing an under-performing well in order to increa its production
2. Fishing – the operation of recovering an object that is stuck, damaged, or lost in the wellbore
NOV Downhole provides a vast range of fishing tools that have become industry standards. The comprehensive list of products includes catch tools, fishing stroking tools such as jars, intensifiers, and bumper subs, junk retrieval tools, milling and cutting tools, as well as repair and remedial tools.
We lead the industry in terms of the size and diversity of our fleet and our ability to provide and rvice tools at a global level.
怪女孩出列Each fishing tool is engineered to perform a specific operation. Since veral fishing tools are utilized to make a fishing bottom hole asmbly, each tool enhances the performance of the others to provide the most effective solution for all types of well intervention and fishing operations.
NOV Downhole’s Bowen Line of Fishing T ools:
External catch fishing tools Internal catch fishing tools Junk retrieval fishing tools Milling and cutting tools Accessory tools
Repair and remedial tools
NOV Downhole offers a computer-bad Fishing Jar Placement Program that determines the optimum jar placement in the fishing string to maximize the energy of the jarring impact and impul. This successful, field-proven placement program compensates for the effects of hole angle, hole curvature, and frictional drag making it applicable for straight, directional, and horizontal hole analysis.
Engineering Services
NOV Downhole provides customized solutions to your specific application. When a special tool is required, our experienced engineering staff is available to evaluate your application and provide a specific and reliable solution.
Milling and Cutting
glory holeFishing tools ud to mill or cut objects downhole for a specific reason. Whether you are milling up a fish that could not be retrieved to surface, cutting casing or tubing in an intervention operation, or performing a washing over procedure, NOV Downhole has the tools for the job.
Remedial and Repair
Scrapers are ud to clean the casing’s inside wall, rollers restore the the inner diameter of casing and tubing to their normal inside diameter and roundness, and patches form a permanent aled connection between two strings of tubing or casing.
Accessory Tools
NOV Downhole offers a variety of tools that enhance the fishing operation. Bumper subs provide you that extra movement in the drillstring when finding the top of the fish, fishing jars create the impact and impul force to free the stuck fish, and our intensifiers are run in conjunction with the fishing jar to increa the jarring impact.
Junk Catch
Fishing tools ud to remove debris, also known as “junk”, from the wellbore. Magnets and junk baskets are ideal when retrieving a fish that is broken into pieces or has an irregular shape.
Internal Catch
Fishing tools that engage the fish in its inner diameter. Similar to External Catch Tools, this is achieved by a grapple or by threading directly to the fish’s inside surface.

Fishing tools that engage the fish on its outer diameter. The tools help you recover equipment downhole by using a grapple or by threading directly to its outside surface.

Series 150 Overshots
Gripping and Releasing Mechanism
The Bowl of the Overshot is designed with helically tapered spiral ction on its inside diameter. The gripping member (Spiral Grapple or Basket Grapple), is fitted into this ction. When an upward pull is exerted against a fish, an expansion strain is spread evenly over a long ction of the bowl and the compression strain is spread evenly over a long ction of the fish. No damage or distortion occurs 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 ction which supports slips.
forgotten
A Spiral Grapple is formed as a left-hand helix with a tapered exterior to conform with the helically tapered ction in the Bowl. Its interior is wickered for engagement with the fish.
A Basket Grapple is an expandable cylinder with a tapered exterior to conform to the helically tapered ction in the Bowl. Its interior is wickered for engagement with the fish. Two types of Basket Grapple are available to meet the need for catching various types of fish.
太空怪人
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 Pack
er. The Basket Grapple with Short Catch Stop (not shown) has a double t of wickers of two different internal diameters. It is ud to stop and catch a coupling with a ruptured piece of pipe engaged in its upper end. The upper t of wickers will catch the ruptured pipe and act as a stop against the coupling, while the lower t of wickers will catch the coupling.
Grapple Controls are of two types: Spiral Grapple Controls are ud with Spiral Grapples; Basket Controls are ud with Basket Grapples. Grapple Controls are ud 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, mill teeth are included. See Packoff Mechanism in this catalog for a complete explanation.

Bowen Series 150 Releasing and Circulating Overshots
The NOV Downhole 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 compod of three outside parts: the Top Sub, Bowl, and Guide. The Basic Overshot may be dresd with either of two ts 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 ud. If the fish diameter is considerably below maximum catch size (usually ½”) a Basket Grapple and a Mill Control Packer are ud.
