Types Of Fishing Tools In Drilling
Introduction
Fishing tools are used in the process of drilling to retrieve lost or stuck equipment inside the wellbore. Sometimes during the drilling process, bits, casing, and other drill string components can become stuck in the wellbore, or become lost in the formation. Fishing tools are used to remove these lost or stuck components, and can be used to re-drill a wellbore or to perform other activities. Fishing tools are designed to be used in a variety of drilling environments, from shallow to deepwater, and from conventional to directional drilling.
Types of Fishing Tools
Fishing tools are available in a variety of shapes and sizes, and can be used for a variety of purposes. Some of the most common types of fishing tools include: overshots, slips, jars, spears, mills, and washover pipes. Overshots are designed to be used in deepwater drilling operations, and are used to retrieve lost drill bits and other components. Slips are designed to grip onto the sides of a wellbore, and are used to retrieve stuck drill string components. Jars are designed to be used in shallow water drilling operations, and are used to break up stuck drill string components or to move them to a new location. Spears are designed to be used in directional drilling operations, and are used to re-drill a wellbore or to remove stuck drill string components. Mills are designed to be used in deepwater and directional drilling operations, and are used to mill out stuck drill string components or to cut away material from the wellbore. Washover pipes are designed to be used in deepwater and directional drilling operations, and are used to remove stuck drill string components or to clean out the wellbore.
Advantages of Fishing Tools
Fishing tools offer a number of advantages in the drilling process. By using fishing tools, operators can save time and money by not having to start over with a new wellbore or drill string. Fishing tools can also be used to perform a variety of other activities, such as sidetracking, or cleaning out the wellbore. Additionally, fishing tools are designed to be used in a variety of drilling environments, from shallow to deepwater, and from conventional to directional drilling.
Disadvantages of Fishing Tools
Fishing tools can be expensive to purchase, and they can also be difficult to operate. Additionally, some fishing tools can be difficult to remove from the wellbore, which can add to the cost of the drilling operation. Furthermore, fishing tools can be dangerous to operate, as they can cause injuries to operators if not used properly.
Conclusion
Fishing tools are an important part of the drilling process, and are used to retrieve lost or stuck drill string components. There are a variety of different types of fishing tools, which can be used in a variety of drilling environments. Fishing tools offer a number of advantages in the drilling process, but they can also be expensive to purchase and difficult to operate. It is important to understand the types of fishing tools available, and how they can be used safely and effectively in the drilling process.
