There are high chances of losing drilling tools in an oilfield. Such situations require the use of fishing devices to retrieve the tools from the oil pit. The choice of instrument depends on the lost fish, where it is, its shape, the extent of damage and its form. Each type of device has a unique craft that makes it suitable for a specific usage. The following are guidelines for selecting oilfield fishing tools to think through.
Acquaint with the usage of external fishing devices. These devices rely on a threading technique that helps them retrieve a product from the surface. Most external retrieval products have a pulling device that captures the exposed fingers of a junk. They use a hydraulic or mechanic procedure that helps them hold the outer part of a fish.
Internal catching devices. These kinds of devices engage the entire junk from its interior. It works similarly to the external catching tools by grappling, but with this one, its grapples at the inside surface. These kinds of devices have a bumper jar that helps in the engagement process and disengaging the junk as well. They have a non-releasable device that has a safety joint that provides emergency disconnect when the junk fails to pull free.
Junk retrieval devices. These kinds of devices remove debris from the oil pit. They use magnetism or use of a junk basket when retrieving the fish. Most junks extracted using these devices are usually broken into pieces. Some of the standard junk retrieval gears include the junk magnet, wireline spear, junk basket, and the impression block.
Devices used in cutting and milling. These devices have a mechanism that mills and grind the fish into small pieces to make them easy to retrieve. They include devices such as strip taper mills, connebuster and other types of devices. Their usage depends on whether the fish is lightweight or are heavyweight. Also, the shape and size of the junks can also affect its retrieval using these devices.
Devices used as fixtures. Particular fixtures work with the internal and external tackles to make them useful. These gears include the bumpers, jars, jar amplifier, and the whipstock. Devices such as the whipstock deflect the fish from its original location for more comfortable fishing. The jar impact amplifier has a piston that use the hydraulic or mechanical technique to provide the jarring power.
Remedial and repair tools. You can also refer to these devices as scrappers. They clean the inside casings of a fished junks and restore their standard inner diameter and roundness. They form a permanent connection between two separate strings of a casing or tubing. Devices that are in this category include the casing rollers and tubing scrapers.
Acknowledge opportunities that can reduce the risk levels. You can reduce the level of risks with fish if you consider some aspects. First, you should have experienced personnel who can handle the fishing process effectively. Apart from that, you need standby gears and insurance coverage as well. The standby gears ensure that retrieval occurs immediately after losing the junks.
