Overshot Fishing Tool: Crucial Equipment for Downhole Recovery in UAE Oil & Gas Operations

In oil and gas drilling, stuck drill pipes, tubing, or casing can halt operations and cost thousands per hour. The overshot fishing tool is one of the most critical solutions, designed to externally grip and retrieve stuck equipment from the wellbore without damaging it.

At JOT Oilfield Services LLC, we provide a full range of overshot tools and fishing solutions across UAE, Oman, and Saudi Arabia, backed by decades of field expertise.

What Is an Overshot Fishing Tool?

Unlike spear tools that grip internally, overshot tools engage the outside of the fish, ensuring secure retrieval and keeping the internal diameter unobstructed. This design is preferred for complex fishing operations requiring high pulling forces and circulation capability.

Key Components

  • Bowl: Houses the grapple and provides strength.
  • Top Sub: Connects to the drill string.
  • Grapple: Main gripping part (spiral or basket type).
  • Grapple Control: Guides movement and torque transfer.
  • Guide: Helps align the fish into the tool.
  • Pack-off: Enables circulation through the fish.

Types of Overshot Fishing Tools

  • Releasing and Circulating Overshots: Standard, with circulation capability and release option.
  • Short Catch Overshots: For short or closely stuck fish.
  • Hydraulic Release Overshots: Ideal in horizontal wells where tool rotation isn’t possible.

Applications in UAE Oil & Gas Operations

  • Drill pipe and casing recovery
  • Tubing and completion equipment retrieval
  • Wellbore cleanup and intervention operations
  • Recovery of stuck downhole tools and components

Advantages

✅ External engagement prevents ID reduction
✅ Wide range of grapple options for various fish diameters and conditions
✅ Allows circulation to aid in freeing stuck equipment
✅ Field-proven design and robust construction for reliability

Best Practices for Successful Fishing

  • Assess fish diameter and condition to choose the right grapple.
  • Use circulation to clear debris and aid retrieval.
  • Apply controlled force; avoid excessive pulling.
  • Follow standard release procedures if the fish cannot be recovered on the first attempt.
