Reversing Spear for Oilfield Drill Pipe, Tubing and Casing Fishing
Internal Catch Fishing Tool for Reliable Pipe Recovery in Drilling and Workover Operations
The SGPE Reversing Spear helps oilfield crews recover drill pipe, oil tubing, casing, liners, and other tubular fish from oil and gas wells. It enters the fish bore, grips the inner wall, and gives the operator firm control during pulling, jarring, cutting, releasing, and retrieval operations.
This oilfield fishing tool works well when the fish keeps an open internal bore but has damaged, worn, or restricted outside surfaces. Crews often run it with a bumper jar, fishing jar, internal cutter, safety joint, drill collar, or other downhole fishing tools to build a practical fishing BHA for drilling, workover, well repair, and well intervention jobs.
SGPE supplies reversing spear models from DLM-T48 to DLM-T340, covering different fish IDs, connection types, casing programs, and pipe recovery requirements.
What Is a Reversing Spear?
A reversing spear is an internal catch fishing tool for retrieving tubular fish from a wellbore. Unlike an overshot, which grips the outside of the fish, this tool enters the bore and catches the fish from the inside.
Oilfield crews use it for drill pipe fishing, tubing recovery, casing fishing, stuck pipe handling, and downhole fish retrieval. After the spear enters the fish, the operator applies rotation, pulling force, or jarring action to engage and recover the fish.
The reversing function gives the crew extra control when the fish cannot move freely or when the fishing assembly needs controlled release.
Key Advantages of SGPE Reversing Spear
Secure Internal Catch
The tool grips the inner wall of the tubular fish and helps maintain stable pulling control during recovery operations.
Practical for Oilfield Conditions
It supports cased hole fishing, open hole fishing, workover service, stuck tubular recovery, and well intervention projects.
Compatible with Fishing BHA
Operators can run the tool with bumper jars, fishing jars, internal cutters, safety joints, drill collars, and other downhole fishing equipment.
Wide Model Coverage
SGPE offers multiple sizes for tubing, drill pipe, casing, liners, and larger tubular fish. This range helps buyers match the tool to different well programs.
Smooth Lead-In Design
The spear rod lead-in helps the tool enter the fish bore more easily, especially when the fish top has minor wear or irregularity.
Technical Selection Support
SGPE can review fish ID, well depth, casing size, connection type, and operation plan before recommending a suitable model.
Oilfield Applications
The SGPE Reversing Spear supports many drilling and workover fishing operations, including:
- Drill pipe fishing after pipe breakage, washout, sticking, or string separation
- Oil tubing recovery during workover, well servicing, and production well repair
- Casing fishing and casing section retrieval in well repair projects
- Tubular fish recovery from cased hole and open hole sections
- Stuck pipe handling in drilling or workover operations
- Downhole fish retrieval after tool failure or pipe parting
- Pipe recovery jobs that require internal catching and controlled pulling
- Fishing operations using bumper jars or fishing jars
- Workover jobs that require internal cutting and fish retrieval
- Well intervention projects involving drill pipe, tubing, casing, or liner recovery
This internal catch design gives the operator a strong option when external fishing tools cannot grip the fish safely or when the wellbore leaves limited outside clearance.
How the Reversing Spear Works
During a fishing job, the crew connects the reversing spear to the fishing string and runs it into the wellbore. When the tool reaches the fish top, the spear rod guides it into the internal bore.
The operator then applies the required rotation and pulling action. The tool engages the inner wall and creates a secure catch. After that, the crew can pull upward or apply impact force through a bumper jar or fishing jar.
If the lower section remains stuck, the crew can combine the reversing spear with an internal cutter. This setup allows the operator to cut the fish at the planned depth and retrieve the upper section. With the right assembly, the tool helps reduce extra trips, shorten fishing time, and improve downhole recovery efficiency.

FAQ – Reversing Spear
1. What is a reversing spear used for in oilfield operations?
A reversing spear helps recover tubular fish from oil and gas wells. Crews use it for drill pipe fishing, oil tubing recovery, casing fishing, stuck pipe handling, and downhole fish retrieval.
The tool enters the fish bore and grips the inner wall. This design works well when the fish has an open internal bore but the outside surface has damage, wear, deformation, or limited clearance.
2. How does a reversing spear catch the fish?
The fishing string carries the tool down to the fish top. The spear rod then guides the tool into the fish bore, and the gripping section engages the inner wall.
After the catch becomes secure, the operator can apply pulling force, rotation, or jarring action. If the fish remains stuck, the crew can add a bumper jar, fishing jar, or internal cutter to complete the recovery operation.
3. What size reversing spear do I need for drill pipe fishing?
The right size depends on the fish internal diameter, minimum fishing size, connection type, wellbore restriction, and pulling requirement.
For drill pipe fishing, the tool must enter the pipe bore smoothly and grip firmly. Please provide drill pipe size, fish ID, well depth, casing size, connection requirement, and fish top condition. SGPE can then recommend a suitable model.
4. Can a reversing spear recover oil tubing from production wells?
Yes. Workover crews often use it to recover broken, stuck, or separated oil tubing from production wells.
In tubing recovery jobs, the tool can run with jars, safety joints, drill collars, and other workover fishing tools. This setup helps improve pulling control, reduce extra trips, and shorten fishing operation time.
5. Can this tool handle casing fishing and large tubular recovery?
Yes. Larger SGPE models can support casing fishing, liner retrieval, and large tubular fish recovery when the tool size matches the fish ID and well condition.
For casing fishing, please confirm casing size, drift diameter, fish top condition, well depth, and connection requirement. These details help SGPE select the correct model and matching fishing assembly.
6. Can a reversing spear work in cased hole and open hole fishing operations?
Yes. The tool can work in both cased hole and open hole fishing operations when the size, fish ID, and BHA design match the well condition.
In cased hole jobs, crews should check casing size, restriction points, and fish position. In open hole jobs, they should also review hole stability, deviation, mud condition, and sticking risk.
7. Can a reversing spear work with a bumper jar or fishing jar?
Yes. Operators often run the tool with a bumper jar or fishing jar during stuck pipe recovery and tubular fish retrieval.
The jar provides impact force when steady pulling cannot move the fish. This combination works well when sand, scale, differential pressure, deformation, or downhole obstruction causes sticking.
8. Can a reversing spear work with an internal cutter?
Yes. The tool can work with an internal cutter when the fishing plan requires cutting and recovering part of the fish.
For example, if the lower section cannot move, the crew can cut the fish at the planned depth and retrieve the upper section. This method helps reduce fishing difficulty and gives the operator more control.
9. What is the difference between a reversing spear and an overshot?
A reversing spear catches the fish from the inside. An overshot catches the outside.
Crews often choose a reversing spear when the fish has an accessible internal bore but limited outside clearance. They may choose an overshot when the fish outside surface remains suitable for external gripping.
10. What information should I provide before ordering?
Please provide:
- Fish type, such as drill pipe, oil tubing, casing, liner, or other tubular fish
- Fish internal diameter and minimum fishing size
- Well depth and casing size
- Fishing string connection requirement
- Fish top condition, such as clean, damaged, collapsed, or worn
- Planned fishing assembly, such as jar, cutter, safety joint, or drill collar
These details help SGPE recommend a suitable model and reduce the risk of tool mismatch.
11. What connections does SGPE offer for reversing spears?
SGPE offers common oilfield connections such as NC26, NC31, NC38, NC50, 2 7/8 REG, and 6 5/8 REG, depending on the model and project requirement.
The connection must match the fishing string and bottom hole assembly. Correct matching improves field installation and supports smoother fishing operations.
12. Can SGPE customize a reversing spear for specific oilfield projects?
Yes. SGPE can discuss customized sizes, connections, and fishing assembly recommendations according to your fish data, well condition, and operation plan.
For special drilling, workover, or well intervention projects, SGPE can review the details before shipment and help buyers choose a practical internal catch fishing solution.
