Fishing

Cutting tubing, casing, or drill pipe using mechanically actuated blades

Used in fishing operations to sever pipe when retrieval is required

Preparing the wellbore for recovery or further intervention after cutting operations

Engaging and retrieving tubing or pipe from the inside diameter during fishing operations

Recovering stuck or parted tubing strings from the wellbore

Providing a secure internal grip when external engagement is not possible

Storing and releasing energy to increase jarring impact in fishing operations

Enhancing effectiveness of jar strings when freeing stuck pipe or tools

Providing additional acceleration to improve impact force in restricted or deep applications

Pulling or freeing stuck casing during workover or abandonment operations

Applying controlled upward force without requiring external power units

Assisting in casing recovery or removal where high load capacity is required

Stuck Dognuts

Providing controlled axial movement in the string to absorb shock and reduce tool damage

Assisting in freeing stuck tools by allowing jarring or bumping action

Used in fishing or intervention operations where limited movement improves tool performance

Reforming or expanding damaged casing to restore internal diameter

Driving through collapsed or restricted sections to regain access downhole

Preparing casing for tool passage or further intervention operations

Engaging and retrieving wireline, rope, or cable from the wellbore

Recovering dropped or parted lines during fishing operations

Providing internal or external grip on soft or flexible fish where standard tools are not effective

Recovering debris, metal fragments, or junk from the wellbore during cleanout operations

Removing loose obstructions prior to fishing or intervention work

Preparing the wellbore for further operations by clearing unwanted material

Determining the size, shape, and condition of fish or obstructions in the wellbore

Identifying engagement points prior to selecting appropriate fishing tools

Assisting in planning recovery operations by providing a physical impression of downhole conditions

Recovering metallic debris or small loose parts from the wellbore

Retrieving dropped tools, bolts, or fragments during cleanout operations

Assisting in wellbore cleanup prior to further intervention or completion work

Delivering impact force to free stuck pipe, tools, or assemblies

Assisting in fishing operations where mechanical force is required to release obstructions

Used in conjunction with jar strings to provide controlled jarring action during intervention work

Cutting threads onto the outside of tubing or pipe to engage and retrieve fish

Recovering pipe where internal tools (like spears) are not suitable

Used in fishing operations when a secure threaded connection is required for pulling

Verifying internal diameter of tubing or casing before running downhole tools

Detecting restrictions, scale, or deformation in the wellbore

Ensuring proper clearance to prevent tool damage or sticking during operations

Engaging and retrieving fish by gripping the outside diameter of tubing or pipe

Recovering stuck or parted pipe during fishing operations

Providing a secure external catch when internal tools (like spears) are not suitable

Providing axial movement in the string to allow controlled bumping action

Assisting in freeing stuck tools or assemblies during fishing operations

Allowing limited stroke to help with tool engagement and manipulation downhole

Engaging and retrieving fish by gripping the outside diameter with aggressive slip design

Recovering damaged or irregular pipe where standard overshots may not hold

Providing a strong external catch in heavy-duty fishing operations

Cutting internal threads into the inside diameter of fish to engage and retrieve pipe

Recovering tubing or drill pipe where internal engagement is preferred

Used in fishing operations when external tools (like overshots or box taps) are not suitable
