What does Fishing Tools mean?
Fishing tools are specialised well workover and intervention tools that are mechanically operated and aid in the recovery or retrieval of other equipment or tools that have fallen into the wellbore by accident or that have been left within the wellbore for unknown reasons. A fishing tool is made up of several additional items that come together to produce a full fishing tool assembly. All of these tools are screwed into the fishing string’s end and dropped into the bore to collect any remaining tools.
Fishing Tools are used to retrieve well equipment such as well tubing, liners, packers, or any other stuck object, according to Bracetool. To continue drilling and preserve the wellbore free of metal debris from oilfield tools and equipment, it becomes necessary to remove all residual or damaged pieces of equipment from the wellbore.
Any tool that has fallen into the wellbore or has remained in the wellbore by accident is referred to as “Junk” or “Fish” on the jobsite. As a result, a fishing tool is a tool that is used to remove fish.
- Diagnostic Devices: These devices assist in diagnosing the surface of the fish or the tool that has been left over in the wellbore so that the fisherman or the operator at the surface can custom construct the fishing tool to facilitate the attachment between the fishing tool and the leftover tool.
- Inside grappling devices: Spears with a threaded and tapered profile are a sort of inside grappling device. These tools can mesh together and undertake a recovery procedure along the threads of the left tool.
- Outside Grappling Devices: These are known as overshots, and they are equipped with threads that swallow the fish and retain it as it is dragged out of the hole.
- Jars or Intensifiers: As the name implies, these tools hammer down on the fish’s surface to create a high impression impact. Later on, the fishing tool can be connected to this imprint to recover the fish or the leftover equipment.
Fishing Techniques
Different Types of Fishing There are numerous techniques to capture a fish. You can catch it with your hands, impale it with a spear, hook it, trap it, and detonate an explosive on it (not recommended and even illegal). Because we’ve been fishing and eating fish for 40,000 years, we’ve had plenty of time to come up with new techniques to catch fish.
